General Soil Map

The general soil map, which is a color map, shows the survey area divided into groups of associated soils called

general soil map units. This map is useful in planning the use and management of large areas.

To find information about your area of interest, locate that area on the map, identify the name of the map unit in the

area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of

the soils in your area.

Detailed Soil Maps

The detailed soil maps can be useful in planning the use and

management of small areas.

To find information about your area

of interest, locate that area on the

Index to Map Sheets. Note the

number of the map sheet and turn

to that sheet.

Locate your area of interest on

the map sheet. Note the map unit

symbols that are in that area. Turn

to the Contents, which lists the

map units by symbol and name

and shows the page where each

map unit is described.

The Contents shows which table

has data on a specific land use for

each detailed soil map unit. Also

see the Contents for sections of

this publication that may address

your specific needs.

This soil survey is a publication of the National Cooperative Soil Survey, a joint effort of the

United States Department of Agriculture and other Federal agencies, State agencies

including the Agricultural Experiment Stations, and local agencies. The Natural Resources

Conservation Service (formerly the Soil Conservation Service) has leadership for the Federal

part of the National Cooperative Soil Survey.

Major fieldwork for this soil survey was completed in 1994. Soil names and descriptions

were approved in 1995. Unless otherwise indicated, statements in this publication refer to

conditions in the survey area in 1994. This survey was made cooperatively by the Natural

Resources Conservation Service and the Forest Service, Bureau of Land Management, and

Oregon Agricultural Experiment Station. The survey is part of the technical assistance

furnished to the Curry County Soil and Water Conservation District.

Soil maps in this survey may be copied without permission. Enlargement of these maps,

however, could cause misunderstanding of the detail of mapping. If enlarged, maps do not

show the small areas of contrasting soils that could have been shown at a larger scale.

Since the publication of this survey, more information on soil properties may have been

collected, new interpretations may have been developed, or existing interpretive criteria may

have been modified. The most current soil information and interpretations for this survey are

in the Field Office Technical Guide (FOTG) at the local field office of the Natural Resources

Conservation Service. The soil maps in this publication are in digital form. The digitizing of the

maps was completed in accordance with the Soil Survey Geographic (SSURGO) database

standards. The digital SSURGO-certified maps are considered the official maps for the

survey area and are part of the FOTG at the local field office of the Natural Resources

Conservation Service.

This soil survey contains information that affects land use planning in this survey

area. It contains predictions of soil behavior for selected land uses. The survey also

highlights soil limitations, improvements needed to overcome the limitations, and the

impact of selected land uses on the environment.

This soil survey is designed for many different users. Farmers, ranchers, foresters,

and agronomists can use it to evaluate the potential of the soil and the management

needed for maximum food and fiber production. Planners, community officials,

engineers, developers, builders, and home buyers can use the survey to plan land use,

select sites for construction, and identify special practices needed to ensure proper

performance. Conservationists, teachers, students, and specialists in recreation, wildlife

management, waste disposal, and pollution control can use the survey to help them

understand, protect, and enhance the environment.

Various land use regulations of Federal, State, and local governments may impose

special restrictions on land use or land treatment. The information in this report is

intended to identify soil properties that are used in making various land use or land

treatment decisions. Statements made in this report are intended to help the land users

identify and reduce the effects of soil limitations that affect various land uses. The

landowner or user is responsible for identifying and complying with existing laws and

regulations.

Great differences in soil properties can occur within short distances. Some soils are

seasonally wet or subject to flooding. Some are shallow to bedrock. Some are too

unstable to be used as a foundation for buildings or roads. Clayey or wet soils are

poorly suited to use as septic tank absorption fields. A high water table makes a soil

poorly suited to basements or underground installations.

These and many other soil properties that affect land use are described in this soil

survey. Broad areas of soils are shown on the general soil map. The location of each

soil is shown on the detailed soil maps. Each soil in the survey area is described.

Information on specific uses is given for each soil. Help in using this publication and

Location of Curry County in Oregon.
19

CURRY COUNTY is in the extreme southwestern

corner of Oregon. Gold Beach is the county seat, and

Brookings presently is the largest city. The county is

characterized by coastal terraces, very narrow river

valleys, and rugged mountains. Elevation ranges from

sea level to 5,316 feet on Brandy Peak, near the

eastern edge of the county. According to the 1990

census, the population of the county was about

20,000.

The total area of the county is 1,054,528 acres, of

which about 356,520 acres is privately owned and

about 698,000 acres is publicly owned. About 620,000

acres of the public land is administered by the Forest

Service, and the remaining 78,000 acres is managed

by the Bureau of Land Management.

Tourism, lumber production, fishing, sheep and

cattle ranching, and specialty crop production are the

major industries in the county. Coastal U.S. Highway

101 is the principal access to the area. Three

wilderness areas are in the county—the Grassy Knob

Wilderness, the Wild Rogue Wilderness, and the

Kalmiopsis Wilderness, which is the largest.

The mean annual rainfall is about 70 to 90 inches

along the populated coastal terraces, 75 to 130 inches

in the higher coastal mountains, and 80 to 160 inches

in the interior regions. The coastal climate is cool and

wet in winter and cool and moist with occasional fog

and low clouds in summer. In the inland areas, the

winters are cool and wet with snow at the higher

elevations and the summers are hot and dry. Most of

the survey area is in two major land resource areas—

the Northern Pacific Coast Range, Foothills, and

Valleys area and the Siskiyou-Trinity area. A small part

at the very southern end of the survey area is in the

California Coastal Redwood area (USDA 1981).

The survey area has more than 180 different kinds

of soil. The soils formed in various kinds of parent

material. The soils in the Klamath Mountains formed in

colluvium and residuum derived from altered igneous

and sedimentary rock, diorite, and scattered areas of

ultramafic rock. The soils in the Coast Range formed

in colluvium and residuum derived from sedimentary

rock and altered igneous rock. The soils on the coastal

terraces formed in marine sediment deposited in an

oceanic environment, and the soils in the river valleys

and on adjacent alluvial fans formed in recent alluvium

derived from mixed sources.

This soil survey updates the survey of Curry Area,

Oregon, published in 1970 (USDA 1970). The earlier

survey covered only the coastal part of the present

survey. The present survey updates the earlier

publication, provides additional information, and has

larger maps that show the soils in greater detail.

History and Development

By Walter G. Schroeder, Curry County agricultural extension

agent, former State representative, and past president of the

Curry County Historical Society.

Curry County was first inhabited by several tribes of

Native Americans who spoke different dialects of a

common Athapascan language. The Athapascan

Indians lived in villages of family groups throughout the

county, primarily in areas at or near the mouth of the

rivers and major creeks. The largest bands were the

Quatomah, which were along the coast from Port

Orford north to the Sixes River, and the Che-a-tee, or

Chetco, which were in and around the BrookingsHarbor Bench area (Curry County 1990).

Other bands included the Kwatami, or Sixes, who

occupied the area south of Bandon to Humbug

Mountain, south of Port Orford; the Cosuttheutun near

Mussel Creek; the Euquachee near Euchre Creek; the

Yashute at the mouth of the Rogue River; the

Tuttutunne, or “people close to the river,” in the vicinity

of the former Bagnell Ferry site; and the Mikonotunne,

or “people among the white clover roots,” near Kimball

Creek (Berreman 1937). The Shista Koostee band

was in the Agness area. The Chetlessnatin band, or

“people by the big rock,” occupied the Pistol River

area, and the Khwaishtunnetunne, or Wishtenatin,

band was near Whaleshead Creek, north of Brookings

(Beckham 1977). The names of the Athapascan bands

commonly ended in “tunne,” meaning people. The

settlers referred to them as Tututni. The majority of

these Native Americans depended on the ocean for

their livelihood and as a source of food. They

subsisted on the abundance of the land, including

camas root, acorn, salmon, smelt, eel, shellfish, deer,

elk, and an occasional seal or beach-stranded whale.

The Native American population at the time of the first

white settlement in the Rogue River country is

estimated to be about 8,800 (Beckham 1971).

The earliest known European excursion along the

southern Oregon Coast occurred in 1543 by

Bartoleme Ferrelo (Cape Ferrelo was named for him),

a Portuguese pilot for the explorer Juan Rodriguez

Cabrillo. In January of 1603, a Spanish squadron

captained by Sebastian Vizcaino, which had sailed

north from Acapulco, Mexico, as an exploring

expedition, became separated in a storm. Vizcaino is

known to have sailed as far north as Cape Sebastian,

which was named for him. In that same year, Martin

D’Aquilar and Antonio Flores, other members of the

squadron, are thought to have reached and named

Cape Blanco, the westernmost point in Oregon

(McArthur 1982). In 1788 and 1792, Captain Robert

Gray of the Royal Navy sailed through coastal waters

off of present-day Curry County. Captain Gray

discovered the Columbia River.

The first known inland expedition occurred in 1826

by Hudson’s Bay Company trappers from Fort

Vancouver. In 1827 Alexander McLeod, a

representative for the Hudson’s Bay Company, was

the first white man to visit the mouth of the Rogue

River (Petersen and Powers 1977). In June 1828,

Jedediah Smith and a party of trappers passed

through the county on a fur trapping and trading

excursion.

William Tichenor, a sea captain who previously

transported goods by steamer between San Francisco

and the Columbia River, had a desire to initiate a

trading settlement along the southern Oregon Coast.

To minimize hauling time, he wanted to build a supply

road inland to settlements in what is now Jackson and

Josephine Counties. Tichenor, who was captain of the

small coastal steamer “Sea Gull,” chose Port Orford for

his settlement because the headlands provided an

excellent sheltering configuration for ships. On June 9,

1851, an advance party of nine men unloaded from

the ship to begin construction of the settlement and a

commercial depot. Promising to return in 14 days,

Tichenor sailed for San Francisco to hire additional

men for the construction work. On June 10, 1851, the

Quatomah Indians attacked, forcing a stand on what is

now called Battle Rock. Fire from muskets and a small

cannon kept the Indians at a safe distance. When

Tichenor’s ship did not arrive as promised, the nine

men fled north during the night to Fort Umpqua, near

Reedsport. Tichenor returned about a month later with

67 men. They built two blockhouses, which are

reported to be the first structures built in the county by

Europeans (Dodge 1969). This became the first

settlement in the county.

Army troops arrived soon afterward and

constructed Fort Orford, which included the first

hospital in southwestern Oregon. Parties were sent

out from Port Orford in the fall of 1851 to cut a trail for

a new trade route to be connected to the Oregon Trail.

This attempt failed, and one of the parties became lost

near a mountain which they named in their

exasperation “Tichenor’s Humbug.” Today the peak is

known simply as Humbug Mountain.

In 1853 Port Orford boasted a store and a sawmill,

which milled cedar that was transported by ship to

San Francisco. In July of that year, settlers began to

migrate into the Chetco Valley and surrounding areas

(present-day Brookings-Harbor Bench area).

In the early 1850’s, gold was discovered in the

upper Rogue River area and in the beach sand along

the coast in Curry County. A rush of prospectors

descended into the area and named the site Gold
Curry County, Oregon 21

Beach. For a time, miners were taking as much as

$50.00 in gold per day from the black beach sand.

When Captain Tichenor later became more prominent

in the area, Gold Beach was changed to Ellensburg in

honor of Tichenor’s daughter, Ellen. In 1890 Ellensburg

was changed back to Gold Beach so that it would not

be mistaken for a town of the same name in the

Washington Territory.

Curry County was established on December 18,

1855, from the southern part of Coos County. It was

named for George Curry, the last governor of the

Oregon Territory before it became the thirty-third state

admitted to the Union on February 14, 1859. Port

Orford was the county seat until 1859, when it was

replaced by Ellensburg, or Gold Beach.

The more permanent miner-settlers planted

gardens to provide food for themselves and to sell to

the prospectors. In 1855 a French-Canadian named

Enos began promoting an uprising among the Indians.

In February of 1856, a group of local Rogue Indians

massacred the male members of the John Geisel

family, who lived at Elizabethtown, a shanty town just

south of present-day Nesika Beach. They took Mrs.

Geisel and her two daughters as temporary prisoners.

They also murdered Indian agent Ben Wright (Dodge

1969). This marked the beginning of the Rogue Indian

Wars, which included skirmishes at Gold Beach and

Pistol River before finally ending on May 27, 1856,

with a battle at Big Bend, near the confluence of the

Rogue and Illinois Rivers. After that battle, 710 Indians

were removed from the county and shipped to

reservations at Grand Ronde and Siletz (Petersen

and Powers 1977). The instigator of the wars, Enos,

was captured and hanged by a lynch mob at Port

Orford.

After the Rogue Indian Wars, the county

experienced rapid growth, particularly at Port Orford.

By 1857 Port Orford consisted of 60 buildings,

including a sawmill, 3 hotels, 8 stores, 2 saloons, a

bowling alley, and 14 army buildings. In the 1860’s

activity in Port Orford declined, and in 1868 a forest

fire leveled a large portion of the town. The lighthouse

at Cape Blanco was built in 1870 to aid ships

navigating the treacherous rocky coast (Petersen and

Powers 1977). Settlement increased at the mouth of

the Rogue River. The plat for Ellensburg was filed, and

a post office was opened.

In 1877 R.D. Hume built a salmon hatchery and

cannery in Ellensburg. This hatchery was the first one

built on the coast in Oregon and only the second one

ever built in the state. The hatchery operated until

1893 when a fire burned down the cannery. Hume

then relocated to the north bank of the Rogue River

and organized a settlement that he called

Wedderburn, named for the Hume ancestral home in

Scotland (Petersen and Powers 1977). A post office

was opened in Wedderburn in 1895.

In 1881 Frank Langlois and A.W. Thrift opened a

store in the northern part of the county. A post office

was also opened, and Frank Langlois became the first

postmaster. His name remained with the settlement,

which developed into the town of Langlois (Petersen

and Powers 1977).

During the 1880’s through the early 1900’s, mining

was a profitable pastime in the area. Borax was mined

at Lone Ranch for 2 years, and gold placer was mined

along many beaches and most of the rivers and

creeks, particularly the Sixes and Pistol Rivers. Nickel

was mined along upper Hunter Creek, and a

sandstone quarry was located at Blacklock Point.

Today, removal of gravel from river bars is the main

remnant of a former large mining industry in the

county.

By 1890 a wagon road connected Coos Bay, Gold

Beach, and Crescent City. This ended use of the

Indian trails that for so many years had been the only

overland routes. When John E. Brookings built a

sawmill in 1908, Brookings became established as a

logging and manufacturing town. A post office was

built there in January 1913. Presently, Brookings is the

largest city in the county. A railroad was constructed

that extended into Del Norte County in California. This

was the only railroad in the county, and it was

destroyed after a depressed lumber market resulted

in the closure of the Brookings mill in 1925. In 1927

U.S. Highway 101 was completed, providing an

all-weather route through the county, and in 1932 the

Rogue River Bridge was completed. Prior to that,

vehicles were ferried across the river at Bagnell

Landing, about 5 miles upriver from present-day Gold

Beach.

During World War II, a U.S. Navy air transport

runway was constructed on Cape Blanco. The runway

is capable of handling jet aircraft, but it is seldom used

today. On September 9, 1942, the county was bombed

twice by a single Japanese submarine-based

floatplane carrying incendiary explosives but little

damage was done. This is believed to be the only

aerial attack on the United States during World War II.

One of the bombing sites is commemorated at Mount

Emily, east of Brookings.

In 1935 Port Orford became the first incorporated

city in the county. Gold Beach followed in 1945 and

Brookings in 1951. A countywide hospital was opened

in Gold Beach in 1951.

Agriculture increased rapidly after the discovery of

gold. Twenty-four years after the Rogue Indian Wars,

farms in the county supported about 22,000 sheep,
22 Soil Survey of

4,000 cows, and 800 hogs (Dodge 1969). The beef

cattle and some of the sheep ranged on the thousands

of acres of open grassland prairies, most of which

have since been overgrown by forests. Hogs fed on

the acorns from tanoak trees in the hills, and a

specialty market for acorn-fed hogs was developed.

Agricultural land was not abundant in the county,

but by 1898 there were 8,000 acres of cultivated land,

mostly along fertile river and creek bottoms, and

50,000 acres of hayland. According to records of the

county treasurer that year, these small acreages of

farmland produced 1,200 bushels of wheat,

20,000 bushels of oats, 5,000 bushels of rye and

barley, 3,000 bushels of corn, 12,000 tons of hay,

500 pounds of tobacco, 30,000 bushels of potatoes,

20,000 bushels of apples, 6,000 bushels of prunes

and plums, and 125,000 pounds of wool while also

maintaining 25,000 sheep, 3,000 hogs, and 10,000

cows (Dodge 1969).

Dairy farming was very important in the county, and

every small town or village had a creamery or cheese

factory.

In 1885 the first cranberry bog on the southern

coast was established by Charles Dexter McFarlin

(Petersen and Powers 1977). Today a multimilliondollar cranberry industry is located in the northern

part of Curry County and the southern part of Coos

County. Potentially, 1,000 acres in the area from Port

Orford to the county line between Coos and Curry

Counties could be used for cranberries. The largest

cranberry farm in Oregon is located in this area. The

climate and other natural resources contribute to the

production of exceptionally high-quality, dark red

berries that are valued by processors for blending.

In the early 1920’s, an Easter lily industry was

started near Bandon and was moved south to the

fertile soils and ideal lily-growing climate of the

Brookings-Harbor Bench area (Petersen and Powers

1977). When Japanese imports were cut off during

World War II, the Easter lily business boomed. Over

95 percent of the lily bulbs supplied for the United

States and Canada are grown in Curry County and

neighboring Del Norte County.

Other specialty crops are grown in various parts of

the county—hydrangeas are grown on the rich soils of

the Harbor Bench area, blueberries are grown

primarily in the northern part of the county, and dahlias

are grown along the Rogue River, near the site of the

former village of the Tuttutunne Indians.

Early logging was largely for local use, but some

lumber was exported. In the 1920’s, a market

developed for Port Orford cedar. More than two-thirds

of the county is publicly owned, and it was not until the

1960’s that much of this land was opened for logging.

Logging and milling boomed until the late 1980’s when

the dwindling supply and environmental pressures

resulted in the closure of many of the mills that

depended on public forests. Some of the best timbergrowing land in the county is privately owned. It

produces excellent yields if intensive management is

used.

The Rogue River and the coast have attracted

tourists for many years. In the 1960’s the tourism

industry started expanding rapidly, and today it is a

major component in the economy of the county.

Physiography, Relief, and Drainage

By Gerald J. Weinheimer, Jr., soil scientist, Natural Resources

Conservation Service.

Physiographically and geologically nearly all of the

county is within the Klamath Mountain geologic

province, which lies at the western edge of the North

American continent, straddling the Oregon-California

border (Dott 1971). This region is characterized by

rugged mountainous terrain and narrow canyons with

2,000 to 5,000 feet of relief. The mountains are made

up largely of pre-Tertiary strata (about 65 million years

old or more) that have been folded, faulted, and in

places intruded by granitoid rock and masses of

serpentinized ultrabasic rock. A small area of the

Coast Range province is in a part of the county where

Eocene sediment (about 65 to 38 million years old) is

exposed in a narrow syncline that extends as far south

as Agness, at the confluence of the Rogue and Illinois

Rivers (Baldwin 1981). The Klamath Mountain region

is underlain by older and more resistant rocks than is

the Coast Range or the Cascade Range, and it has

undergone longer and more complicated erosional

processes (Dicken 1976).

Curry County has a relatively complex geologic

history that is reflected by the wide variety of rock

types in the county and the extent of deformation. The

geologic bedrock units are composed of sedimentary

rock, various types of igneous rock, and metamorphic,

or altered, rock. These bedrock units range in age

from 150 million years old to less than 10 million

years old. Pre-tertiary sedimentary rock that covers

most of the county has been folded and thrust faulted.

This sandstone, siltstone, and mudstone is highly

fractured, and little bedding remains. The stratified, or

well-bedded, Tertiary sandstone and siltstone are

primarily in the north-central part of the county (about

65 million to 2 million years old). The types of igneous

rock are mainly granitelike rock, which has formed

many of the more rugged mountains, and peridotite,

which has altered to serpentinite. The metamorphic
Curry County, Oregon 23

rock consists mainly of schist and phyllite that formed

as a result of heat and pressure applied to

sedimentary rock (Ramp and others 1977).

Surficial geologic units consist of semiconsolidated

to unconsolidated terrace and lowland deposits

that locally overlie the bedrock units. These geologic

units were formed by relatively recent geologic

processes. They range to 2 million years old, but most

are less than 100,000 years old. Surficial deposits

differ from soils in that they are products of deposition

rather then weathering (Beaulieu 1976).

All but the very youngest of the geologic units have

undergone deformation through tectonic processes

such as folding, faulting, and thrusting at various

times in the past. Much of the deformation by faulting,

which has caused the fracturing and partial

mechanical disintegration of the geologic units, has

been localized in place and time. The Pistol River

shear zone, which is an area of localized faulting,

consists of a heterogeneous mixture of intensely

sheared rock and serpentinite pods extending in a

southeasterly direction from Cape Sebastian to

Carpenterville. Linear arrangements of sea stacks

such as at Mack Reef, south of Crook Point, represent

the resistant tectonic blocks within shear zones. A

second area of localized faulting is in the northern part

of the county along the coast. It extends from Cape

Blanco south through Port Orford to southeast of

Humbug Mountain. Part of this shear zone is offshore

on the continental shelf. Orford Reef is the resistant

tectonic block associated with this zone.

These faults appear to have been active in the

distant geologic past and are not a threat in terms of

earthquake activity; however, the highly fractured rock

presents a significant risk of landslides in the

immediate vicinity of the shear zone. Generally, most

areas in the county are subject to landslides or to

instability of the soils because of the diverse nature of

the rock and its origin, the kinds of soils derived from

the rock, the deformation of the bedrock units by

tectonic processes, the high-relief topography, and the

high amount of rainfall in winter.

The county is typified by lowlands, terraces, and

mountains. The lowlands consist of the areas within

the present flood plains, marshes, and deflation plain

between the beaches and dunes at or near the

mouth of larger rivers and streams along the coast.

The major flood plains are along the Rogue, Illinois,

Chetco, and Winchuck Rivers and several of the

larger creeks in the county. The areas subject to

flooding are narrow stretches and depressional

channels adjacent to the streams. Elevation generally

is less than 40 feet above sea level. An exception is

some areas of sand dunes, such as those south of the

mouth of the Pistol River, but these areas are of

minor extent.

The terraces consist of two types—marine

terraces and river terraces. The marine terraces

consist of remnants of past sea floor levels elevated

by recent uplift, and the river terraces consist of

dissected remnants of former flood plains along

major streams. Several distinct levels of marine

terraces have been recognized on the coastal plain

extending from Port Orford northward into Coos

County. They have areas of poorly consolidated sand

and gravel from a few feet thick to more than 100 feet

thick and have been dissected by major coastal

streams. Elevation of the younger coastal terraces

generally is less than 200 feet; however, it ranges

from 20 to 650 feet because of the considerable

continuous submarine seismic activity offshore.

The lower terraces generally have only a partially

developed drainage network. Remnants of older

terraces are at higher elevations (1,000 to 1,500 feet),

such as in the area between the Elk and Sixes Rivers,

north of Port Orford, and at the Brookings Airport.

These older, higher terraces are strongly dissected

and well drained by a highly developed drainage

network. Smaller sets of marine terraces are north of

Gold Beach and south of Brookings. River terraces

generally are less than 50 feet above the present-day

flood plains (Beaulieu 1976). The higher stream

terraces are somewhat wide, nearly level areas. The

widest terraces are in the Agness and upper Sixes

River areas. Alluvial fans are on relatively steep,

short slopes in narrow river valleys.

A more detailed discussion of the terraces in the

county is given in the section “Formation of the

Soils.” Terraces are of significant extent in the county,

and they are of major importance as sites for

commercial, residential, industrial, and agricultural

development.

The Coast and Klamath Ranges are the principal

mountains in the county. The mountain slopes are

steep, long, and dissected. The mountains range in

elevation from about 1,700 feet at Humbug Mountain,

adjacent to the ocean, to more than 5,300 feet inland

at Brandy Peak. The higher elevations exhibit evidence

of glaciation, with several small glacial lakes in the

cirque basins.

The county is drained by two major rivers, the

Rogue and Illinois Rivers, and several smaller rivers,

including the Winchuck, Chetco, Pistol, Elk, and Sixes

Rivers. These rivers flow in a westerly or northwesterly

direction to the Pacific Ocean. The North Fork of the

Smith River drains to the south into California. Several

well-developed stream systems, such as Floras,

Euchre, and Hunter Creeks, drain the smaller basins.
24 Soil Survey of

Natural Resources

The many natural resources of the county are

varied and unique. They include the outstanding visual

quality of the landscape, diverse forest products,

abundant anadromous fish and wildlife species,

economically important mineral deposits, and

agricultural products such as specialty crops.

The landscape is rapidly becoming the most

valuable natural resource of the county. Tourism and

related businesses are developing into a major

enterprise. The wealth of water, wildlife, and scenery

and the sunny weather attract thousands of visitors

annually.

A variety of forest products from private and public

land generates employment for many of the residents

in the county. The forest products are a major source

of revenue for the local government. Lumber, plywood,

and wood chips are produced for domestic use and for

export.

Recreational and commercial fishing in the Pacific

Ocean and in coastal rivers is of tremendous

economic importance, and it is tied directly to the

health of the land and the ocean. Salmon is the most

sought-after and valuable species.

Limited interest in mining continues. Small placer

gold prospects are along the rivers and streams and

large deposits of low-grade nickel and associated

minerals are in areas of serpentinized peridotite in the

interior mountains. These areas are controlled by

companies that have large blocks of mining claims.

The deposits will be processed when it becomes

economically feasible to do so.

Specialty crops such as cranberries and lily bulbs

are suited to the maritime climate of the county.

Sheep and cattle ranching also is profitable because

of the year-round growing season for pasture

grasses.

Forestland

The county is one of the better timber-growing

areas in southwestern Oregon. About 90 percent of

the county is classified as commercial forestland.

About 66 percent of the county is commercial

forestland that is publicly owned. Of this, about 59

percent is in the Siskiyou National Forest and is

administered by the Forest Service, 6 percent is

administered by the Bureau of Land Management,

and 1 percent is administered by the State and county.

About 24 percent of the county is commercial

forestland that is privately owned. Of this, about 20

percent is owned by the forest products industry and

4 percent by small woodland operators.

The principal forest cover type is the

Douglas fir/Tanoak/Pacific madrone type, which is

throughout the majority of the county (Eyre 1980).

Other forest cover types include the Sitka spruce type

along most of the coastal zone; the Redwood type

south of the Chetco River; the Jeffrey pine type

associated with the serpentine-influenced soils; and

the White fir and Shasta red fir types, which are inland

and at the higher elevations (Eyre 1980). Stands of

tanoak, Pacific madrone, Oregon white oak, red alder,

incense cedar, western redcedar, and bigleaf maple

can be harvested for specialty products such as

furniture, fuelwood, and wood chips.

The forestland in the county is protected from fire

by the Forest Service, the Oregon State Department

of Forestry through the Coos Forest Protection

Association, and the local fire districts. The increasing

population and recreational activity in the area make

accidental fire a constant threat, especially during the

dry period in summer.

Climate

Curry County has a marine-influenced climate

because of its proximity to the Pacific Ocean, which

warms the air flowing over the county in winter and

cools the air in summer. As a result, temperatures

along the coast are mild throughout the year. The

coastal marine influence decreases in inland areas,

resulting in greater variations in temperature.

Precipitation is perhaps the most significant climatic

factor in the county. Rainfall is highest in December

and lowest in July.

Winds from the west travel over the ocean for

several days. When the airmass reaches land, it is

saturated with moisture and is at nearly the same

temperature as the ocean. This results in about 100

days of fog along the coast each year. In the inland

valleys, however, the number of foggy days may be

about half that of the coastal areas. Fog occurs in all

months, but it occurs dominantly in October through

March. In general, the northern part of the county,

particularly Cape Blanco, receives more wind and

stronger wind, and the southern part, particularly the

Brookings-Harbor Bench area, receives more fog.

The mountains begin within a few miles of the

coastline. They rise to elevations of more than 5,000

feet. Airmasses flowing over the mountains cool by as

much as 3 to 5 degrees F for each 1,000-foot increase

in elevation.

In winter, landmasses cool to a much lower

temperature than the ocean and they cool the

airmasses as they rise up the mountainslopes. As this

cooling takes place, air that was nearly saturated at
Curry County, Oregon 25

sea level becomes oversaturated. As a result,

precipitation increases as elevation increases (Meyer

and Amaranthus 1979).

In summer, landmasses heat up more rapidly than

does the ocean and thus less precipitation is produced

in the airmasses as they move up the mountain

slopes. For this reason, the inland valleys, which are

15 to 30 miles from the coast, are drier and warmer

than the coastal areas.

Local variations in the climate of the county result in

variations in vegetation patterns. An example is in the

northern part of the county where the more frequent

storms and fog produce a cooler climate. In this part,

trees such as western hemlock and western redcedar

commonly are in the forest canopy, while further south

these trees occur only sporadically. In the northern

part of the county, red alder competes with tanoak,

which is dominant in the southern part, to become the

major hardwood species in the forest stands. Another

example is in the very southern part of the county.

According to Weather Bureau data, the average

temperature at Brookings is about 1.9 degrees F

higher than that at Bandon. Gold Beach and Brookings

are nearly free of frost (Atzet and Wheeler 1984).

Mainly because of the warmer, frost-free conditions,

the northernmost extension of the Redwood forest

cover type on the Pacific Coast is in this area.

The strong marine influence on the coastal

mountains and the western side of the Klamath

Mountains is characterized by high precipitation and

humidity, abundant fog, and a limited range in

temperature. These characteristics tend to lower the

rates of evaporation and transpiration, and

condensation from the fog increases the available soil

moisture. Generally, moist airmasses move from the

southwest to the northeast late in fall, in winter, and

early in spring. The prevailing drier winds in summer

are from the northwest. Normal annual rainfall ranges

from 70 to 160 inches. The rainy season extends from

mid-October to mid-April. Seventy-five to eighty

percent of the total annual precipitation falls during

this period. Local wind patterns influence the

distribution of the rainfall by funneling airmasses up

major drainageways. The amount of rainfall increases

as elevation increases. As the distance from the

coast increases, snowfall becomes more common

at the higher elevations. The snow rarely is more

than 1 to 2 feet deep, and it commonly melts by

midspring.

The mean temperature in January is about 40 to 45

degrees. Infrequent periods of extremes of as low as

zero occur in winter. The mean temperature in July is

about 60 to 65 degrees. Infrequent, short periods of

extremes of more than 100 degrees occur in summer.

In fall and winter, low-pressure systems form in the

North Pacific Ocean and produce counterclockwise

patterns of air circulation that result in prevailing

winds approaching from the southwest. Coastal

storms in winter commonly have high-velocity,

southwesterly or westerly winds. The winds

commonly reach 40 miles per hour. Occasional gusts

of more than 120 miles per hour have been recorded

at Cape Blanco.

The eastern side of the Klamath Mountains has a

different climate as a result of the incoming marine

airmasses having been greatly modified during their

passage up the western slopes. Considerable

amounts of the available moisture in the airmasses

are condensed and precipitated on the western

slopes. The amount of fog and the humidity are lower

on the eastern side and the rate of evapotranspiration

is higher as a result of the landmasses heating and

cooling more rapidly than the ocean airmasses, which

tends to increase the temperature extremes. Snow is

common at the higher elevations, but it rarely is more

than 2 to 3 feet deep and normally lasts only until

midspring.

The mean temperature in January ranges from 35

to 40 degrees, and the mean temperature in July

ranges from about 65 to 69 degrees. Short periods of

temperature extremes ranging from below zero in

winter to more than 100 degrees in summer occur

infrequently. The winds are from the southwest, and

the maximum velocity during winter storms is rarely

more than 50 miles per hour. Most of the total annual

precipitation occurs in November through mid-April.

In midspring, high pressure replaces the winter

low-pressure centers. This changes the pattern of air

circulation to prevailing northwesterly winds and

produces a dry season from midspring to late in spring

that intensifies through the summer and ends early in

fall. Thunderstorms are more frequent in summer, and

they commonly approach from the south. Precipitation

from the thunderstorms commonly is light; only about

5 percent of the annual precipitation is received in

summer.

Table 1 gives data on temperature and precipitation

for the survey area as recorded in the period 1962 to

1991 at Bandon, Brookings, Gold Beach, and Illahe,

Oregon, and in the period 1965 to 1993 at Port Orford,

Oregon. Table 2 shows probable dates of the first

freeze in fall and the last freeze in spring. Table 3

provides data on length of the growing season.

Growing degree days are shown in table 1. They

are equivalent to “heat units.” During the month,

growing degree days accumulate by the amount that

the average temperature each day exceeds a base

temperature (40 degrees F). The normal monthly
26 Soil Survey of

accumulation is used to schedule single or successive

plantings of a crop between the last freeze in spring

and the first freeze in fall.

How This Survey Was Made

This survey was made to provide information about

the soils and miscellaneous areas in the survey area.

The information includes a description of the soils and

miscellaneous areas and their location and a

discussion of their suitability, limitations, and

management for specified uses. Soil scientists

observed the steepness, length, and shape of the

slopes; the general pattern of drainage; the kinds of

crops and native plants; and the kinds of bedrock.

They dug many holes to study the soil profile, which is

the sequence of natural layers, or horizons, in a soil.

The profile extends from the surface down into the

unconsolidated material in which the soil formed. The

unconsolidated material is devoid of roots and other

living organisms and has not been changed by other

biological activity. The soils and miscellaneous areas

in the survey area are in an orderly pattern that is

related to the geology, landforms, relief, climate, and

natural vegetation of the area. Each kind of soil and

miscellaneous area is associated with a particular kind

of landform or with a segment of the landform. By

observing the soils and miscellaneous areas in the

survey area and relating their position to specific

segments of the landform, a soil scientist develops a

concept or model of how they were formed. Thus,

during mapping, this model enables the soil scientist

to predict with a considerable degree of accuracy the

kind of soil or miscellaneous area at a specific location

on the landscape.

Commonly, individual soils on the landscape merge

into one another as their characteristics gradually

change. To construct an accurate soil map, however,

soil scientists must determine the boundaries between

the soils. They can observe only a limited number of

soil profiles. Nevertheless, these observations,

supplemented by an understanding of the soilvegetation-landscape relationship, are sufficient to

verify predictions of the kinds of soil in an area and to

determine the boundaries.

Soil scientists recorded the characteristics of the

soil profiles that they studied. They noted color,

texture, size and shape of soil aggregates, kind and

amount of rock fragments, distribution of plant roots,

reaction, and other features that enable them to

identify soils. After describing the soils in the survey

area and determining their properties, the soil

scientists assigned the soils to taxonomic classes

(units). Taxonomic classes are concepts. Each

taxonomic class has a set of soil characteristics with

precisely defined limits. The classes are used as a

basis for comparison to classify soils systematically.

Soil taxonomy, the system of taxonomic classification

used in the United States, is based mainly on the kind

and character of soil properties and the arrangement

of horizons within the profile. After the soil scientists

classified and named the soils in the survey area, they

compared the individual soils with similar soils in the

same taxonomic class in other areas so that they

could confirm data and assemble additional data

based on experience and research.

While a soil survey is in progress, samples of some

of the soils in the area generally are collected for

laboratory analyses and for engineering tests. Soil

scientists interpret the data from these analyses and

tests as well as the field-observed characteristics and

the soil properties to determine the expected behavior

of the soils under different uses. Interpretations for all

of the soils are field tested through observation of the

soils in different uses and under different levels of

management. Some interpretations are modified to fit

local conditions, and some new interpretations are

developed to meet local needs. Data are assembled

from other sources, such as research information,

production records, and field experience of specialists.

For example, data on crop yields under defined levels

of management are assembled from farm records and

from field or plot experiments on the same kinds of

soil.

Predictions about soil behavior are based not only

on soil properties but also on such variables as

climate and biological activity. Soil conditions are

predictable over long periods of time, but they are not

predictable from year to year. For example, soil

scientists can predict with a fairly high degree of

accuracy that a given soil will have a high water table

within certain depths in most years, but they cannot

predict that a high water table will always be at a

specific level in the soil on a specific date.

After soil scientists located and identified the

significant natural bodies of soil in the survey area,

they drew the boundaries of these bodies on aerial

photographs and identified each as a specific map

unit. Aerial photographs show trees, buildings, fields,

roads, and rivers, all of which help in locating

boundaries accurately.

Survey Procedures

The general procedures used in making this soil

survey are described in the National Soils Handbook

of the Natural Resources Conservation Service.

References used in the development of this survey
Curry County, Oregon 27

include an earlier soil survey of Curry Area, Oregon,

published in 1970 (USDA 1970); mapping of

geomorphic surfaces on marine and stream terraces;

the soil inventory of the Medford District published in

1975 (deMoulin and others 1975); the soil inventory

of the Coos Bay District published in 1977 (Townsend

and others 1977); the soil resource inventory of

Siskiyou National Forest published in 1979 (Meyer and

Amaranthus 1979); reconnaissance geologic maps

with accompanying texts issued in 1976 and 1977

(Beaulieu 1976, Ramp and others 1977); and the

memorandum of understanding between the Natural

Resources Conservation Service and the Forest

Service, Bureau of Land Management, and Oregon

State University Agricultural Experiment Station.

The survey area was mapped using high-altitude

aerial photographs enlarged to a scale of 1:20,000.

Selected cultural features and hydrography on the

soil maps were based on U.S. Geological Survey

7.5-minute topographic quadrangle maps. Hillslopes

and relief gradients were determined either by

examination of contour intervals on topographic maps

or by stereoscopic study of aerial photographs.

The specifications for intensity of soil mapping

varied by geographic area within the survey area and

were based on the needs of the user. More information

on the detail of mapping is given in the memorandum

of understanding for this survey.

The soils in the survey area were mapped

according to predictable soil patterns that occur on

landforms. The general soil-landform relationships are

described in detail in the section “Formation of the

Soils.” Transects and traverses were used to confirm

soil-landform patterns.

Tonal patterns on aerial photographs were used

to predict the presence of wet, droughty, or shallow

soils, cobbles or stones, and eroded or unvegetated

areas. The type and density of vegetation commonly

reflect soil depth, available water capacity, and aspect.

Transects were used to map areas where the soils

do not occur in predictable patterns. Soils in level

areas, such as flood plains and marine terraces, are

examples. Transects were made randomly across the

areas to determine the composition of the dominant

and minor soils. Tonal patterns on aerial photographs

were used to predict some preliminary soil

delineations, although the extent and composition of

each map unit was determined in the field. The soil

scientists generally crossed the areas on foot,

following a course that had been determined from

aerial photographs. The soil characteristics were

examined at regular intervals and documented.

Several delineations commonly are on a single

landform.

Map unit delineations were divided into two

categories—similar soils and contrasting soils. Similar

soils have the same potential plant communities and

similar use and management requirements.

Contrasting soils have different potential plant

communities and different use and management

requirements. The contrasting soils or miscellaneous

areas that are of significant extent are described in the

section “Detailed Soil Map Units.”

Where predictable soil patterns existed, such as on

foothills and in mountainous areas, traverses were

made to correlate a soil with a particular landscape

position. Traverses were planned through the use of

topographic quadrangle maps and photo-interpretation

of tonal patterns, slope, and aspect. Point data

collected in the field was used to determine the

composition of map units, to determine the range of

characteristics for each named soil in the map units,

and to verify predictions of the occurrences of different

kinds of soil. The traverses were made by truck and on

foot. The soil was examined when changes in

characteristics were apparent. Where the soils varied

considerably, many traverses were made at short

intervals.

This soil survey was mapped at three levels of

intensity. A high level of detail was used to map the

soils on marine terraces, in coastal stream valleys,

and on low foothills. There is increasing pressure to

develop the cropland and pastureland in these areas.

Map units used were consociations and complexes of

phases of soil series or miscellaneous areas. Maps of

the flood plains published by the Federal Emergency

Management Agency were used as an aid in

determining the boundaries of the flood plains. The

minimum size of a map unit delineation was 10 acres.

The maximum size of a delineation of contrasting soils

was about 1.5 acres on terraces and 12 acres on

foothills. About 6 percent of the survey area was

mapped at this high level of detail.

An intermediate level of detail was used to map the

soils of the remaining foothills and the nonwilderness

mountainous areas. These soils formed in various

kinds of parent material and are gently sloping to very

steep. They are used for timber production, livestock

grazing, watershed, recreation, and fish and wildlife

habitat. The map units used were complexes of

phases of soil series and miscellaneous areas. The

minimum size of a map unit delineation commonly was

about 80 acres; however, delineations as small as 15

acres were made in areas that were considered to be

of high value. About 76 percent of the survey area was

mapped at this level of detail.

A low level of detail was used to map the soils of

the three mountainous wilderness areas recognized in
28

the survey area. These soils formed in various kinds of

parent material and are strongly sloping to very steep.

They are used for aesthetic value and as watershed,

recreation, and fish and wildlife habitat. The map units

used were complexes of phases of soil series and

miscellaneous areas. The minimum size of a map unit

delineation commonly was about 320 acres; however,

delineations as small as 40 acres were made in areas

recognized by cooperating agencies as having unique

value or that were accessible for transects and

enhanced field investigation. Based on accessibility,

transects and landform traverses were made at

strategic locations. This point data was used to

establish general soil-landform associations and to

locate representative soil profiles. About 18 percent of

the survey area was mapped at this level.

The soil mapping of the marine terraces, coastal

stream valleys, and some of the adjacent foothills and

mountainous areas is a revision of the mapping done

for the soil survey of Curry Area, Oregon, published in

1977 (USDA 1977). Since that time, more has been

learned about the soils through laboratory analysis

and through examination of data on crop yields and

productivity of timber sites. Previous concepts have

been revised as a result of this knowledge.

Samples for chemical and physical analysis were

taken from pedons of the major soils in the survey

area. The analyses were made by the National Soil

Survey Laboratory in Lincoln, Nebraska, and by the

soils laboratory at Oregon State University. The results

were used in classifying the soils, in determining their

fertility and erodibility, and in making various

interpretations for engineering and agricultural uses

and for other land uses.

Soil-plant relationships were evaluated during the

development of the detailed map unit descriptions;

thus, data on the productivity of trees and yield of

crops is included in this survey. Foresters, soil

scientists, and soil conservation technicians assisted

in measuring the potential for timber production at

representative forested sites. Foresters and ecologists

correlated existing vegetation to potential plant

communities, and soil scientists correlated these

plant communities to soil series and map unit

concepts. Soil conservationists, agents of the Oregon

State University Extension Service, and Earth Team

volunteers assisted in collecting yield data for specialty

crops and forage.

More detailed information about soils, forestry,

and vegetation is given in the sections “Crops and

Pasture” and “Forestland Management and

Productivity.”

The general soil map at the back of this publication

shows broad areas that have a distinctive pattern of

soils, relief, and drainage. Each map unit on the

general soil map is a unique natural landscape.

Typically, it consists of one or more major soils or

miscellaneous areas and some minor soils or

miscellaneous areas. It is named for the major soils or

miscellaneous areas. The components of one map unit

can occur in another but in a different pattern.

The general soil map can be used to compare the

suitability of large areas for general land uses. Areas

of suitable soils can be identified on the map. Likewise,

areas where the soils are not suitable can be

identified.

Because of its small scale, the map is not suitable

for planning the management of a farm or field or for

selecting a site for a road or building or other structure.

The soils in any one map unit differ from place to place

in slope, depth, drainage, and other characteristics

that affect management.

The map units delineated on the detailed maps at

the back of this survey represent the soils or

miscellaneous areas in the survey area. The map unit

descriptions in this section, along with the maps, can

be used to determine the suitability and potential of a

unit for specific uses. They also can be used to plan

the management needed for those uses. More

information about each map unit is given under the

heading “Use and Management of the Soils.”

A map unit delineation on a map represents an area

dominated by one or more major kinds of soil or

miscellaneous areas. A map unit is identified and

named according to the taxonomic classification of the

dominant soils or miscellaneous areas. Within a

taxonomic class there are precisely defined limits for

the properties of the soils. On the landscape, however,

the soils and miscellaneous areas are natural

phenomena, and they have the characteristic

variability of all natural phenomena. Thus, the range of

some observed properties may extend beyond the

limits defined for a taxonomic class. Areas of soils of a

single taxonomic class rarely, if ever, can be mapped

without including areas of other taxonomic classes.

Consequently, every map unit is made up of the soils

or miscellaneous areas for which it is named and

some “included” areas that belong to other taxonomic

classes.

Most included soils have properties similar to those

of the dominant soil or soils in the map unit, and thus

they do not affect use and management. These are

called noncontrasting, or similar, inclusions. They may

or may not be mentioned in the map unit description.

Other included soils and miscellaneous areas,

however, have properties and behavioral

characteristics divergent enough to affect use or to

require different management. These are called

contrasting, or dissimilar, inclusions. They generally

are in small areas and could not be mapped

separately because of the scale used. Some small

areas of strongly contrasting soils or miscellaneous

areas are identified by a special symbol on the maps.

The included areas of contrasting soils or

miscellaneous areas are mentioned in the map unit

descriptions. A few included areas may not have been

observed, and consequently they are not mentioned in

the descriptions, especially where the pattern was so

complex that it was impractical to make enough

observations to identify all the soils and miscellaneous

areas of the landscape.

The presence of included areas in a map unit in no

way diminishes the usefulness or accuracy of the data.

The objective of mapping is not to delineate pure

taxonomic classes but rather to separate the

landscape into landforms or landform segments that

have similar use and management requirements. The

delineation of such segments on the map provides

sufficient information for the development of resource

plans, but if intensive use of small areas is planned,

onsite investigation is needed to define and locate the

soils and miscellaneous areas.

An identifying symbol precedes the map unit name

in the map unit descriptions. Each description includes

general facts about the unit and gives the principal

hazards and limitations to be considered in planning

for specific uses.

Soils that have profiles that are almost alike make

up a soil series. Except for differences in texture of the

surface layer, all the soils of a series have major

horizons that are similar in composition, thickness,

and arrangement.

Soils of one series can differ in texture of the

surface layer, slope, stoniness, salinity, degree of

erosion, and other characteristics that affect their use.

On the basis of such differences, a soil series is

divided into soil phases. Most of the areas shown on

the detailed soil maps are phases of soil series. The

name of a soil phase commonly indicates a feature

that affects use or management. For example,

Winchuck silt loam, 3 to 15 percent slopes, is a phase

of the Winchuck series.

Some map units are made up of two or more major

soils or miscellaneous areas. These map units are

complexes.

A complex consists of two or more soils or

miscellaneous areas in such an intricate pattern or in

such small areas that they cannot be shown

separately on the maps. The pattern and proportion of

the soils or miscellaneous areas are somewhat similar

in all areas. Agness-Sixes-Goldbeach complex, 30 to

60 percent south slopes, is an example.

This soil survey is an inventory and evaluation of

the soils in the survey area. It can be used to adjust

land uses to the limitations and potentials of natural

resources and the environment. Also, it can help to

prevent soil-related failures in land uses.

In preparing a soil survey, soil scientists,

conservationists, engineers, and others collect

extensive field data about the nature and behavioral

characteristics of the soils. They collect data on

erosion, droughtiness, flooding, and other factors that

affect various soil uses and management. Field

experience and collected data on soil properties and

performance are used as a basis in predicting soil

behavior.

Information in this section can be used to plan the

use and management of soils for crops and pasture;

as woodland; as sites for buildings, sanitary facilities,

highways and other transportation systems, and parks

and other recreational facilities; and for wildlife habitat.

It can be used to identify the potentials and limitations

of each soil for specific land uses and to help prevent

construction failures caused by unfavorable soil

properties.

Planners and others using soil survey information

can evaluate the effect of specific land uses on

productivity and on the environment in all or part of the

survey area. The survey can help planners to maintain

or create a land use pattern in harmony with the

natural soil.

Contractors can use this survey to locate sources

of sand and gravel, roadfill, and topsoil. They can use

it to identify areas where bedrock, wetness, or very

firm soil layers can cause difficulty in excavation.

Health officials, highway officials, engineers, and

others may also find this survey useful. The survey

can help them plan the safe disposal of wastes and

locate sites for pavements, sidewalks, campgrounds,

playgrounds, lawns, and trees and shrubs.

Crops and Pasture

Edward A. Petersen, district conservationist, Natural Resources

Conservation Service; Arthur P. Poole, horticulture extension agent,

Oregon State University Extension Service; and Lee Riddle,

research station manager, Easter Lily Research Foundation,

helped to write this section.

General management needed for crops and pasture

is suggested in this section. The estimated yields of

the main crops and pasture plants are listed for each

soil, the system of land capability classification used

by the Natural Resources Conservation Service is

explained, and prime farmland is described.

Planners of management systems for individual

fields or farms should consider the detailed

information given in the description of each soil under

the heading “Detailed Soil Map Units.” Specific

information can be obtained from the local office of the

Natural Resources Conservation Service or the

Cooperative Extension Service.

The soils in this survey area have many

characteristics that affect their behavior and the types

of resource management systems needed for various

uses. The productivity of each kind of soil under

specific management conditions can be maintained or

improved only if the unique characteristics of the soils

are understood and the best resource management

practices are applied. One such characteristic is the

susceptibility of the soils to compaction if farm

machinery or other vehicles are used or if livestock is

allowed on the soils at improper times. Soil

compaction results in reduced permeability, a lower

water intake rate, restricted root development, poor

tilth, and increased runoff and erosion, all of which

adversely affect both the productivity of the soils and

the conservation of soil and water.

Several practices can be used to prevent or

minimize soil compaction. Using different types of

tillage equipment and periodically adjusting the

operating depth of the equipment help to minimize

compaction. Restricting tillage, equipment use, and

livestock traffic when the soils are wet can minimize

the risk of compaction. Heavy, season-long grazing in

riparian areas may decrease the abundance of plants

that help to stabilize streambanks and moderate water

temperatures. Low-pressure floatation equipment can

be used to minimize compaction on soils such as

those of the Brenner, Chetco, Hebo, Huffling, Langlois,

Pyburn, Quosatana, Willanch, and Zyzzug series,

which are wet for extended periods because of a high

water table, and on soils such as those of the

Cashner, Depoe, and Joeney series, which are wet for

Use and Management of the Soils
306 Soil Survey of

extended periods because subsurface water is

perched on a restrictive cemented iron pan in the

soils.

The hazard of erosion is of great concern,

especially on those soils that are subject to flooding

and those that have steeper slopes. Soils that are

subject to flooding are those of the Bagness, Bayside,

Bigriver, Brenner, Chetco, Evans, Gauldy, Heceta,

Kirkendall, Langlois, Nehalem, Nestucca, Pistolriver,

Quosatana, Willanch, Yachats, and Yaquina series.

Generally, the greater the slope of a soil the greater

the risk of erosion because of the increased velocity of

the water. The length of the slope can compound the

problem by allowing greater concentrations of water

from runoff. Soils on the foothills, such as those of the

Barkshanty, Burnthill, Carpenterville, Edson, Etelka,

Grassyknob, Hazelcamp, Hooskanaden, Houstenader,

Loneranch, McDuff, Orford, Reedsport,

Skookumhouse, Svensen, Templeton, Wedderburn,

Whobrey, and Zwagg series, must be carefully

managed because of the slope and the subsequent

need for erosion-control practices. Conservation tillage

and contour plowing help to minimize erosion.

Barren soils are subject to detachment of individual

soil particles by rainfall and by irrigation water from

sprinklers. Once detached, the particles can be

transported by surface runoff. Soil erosion as a result

of runoff reduces the productivity of the soil unless

conservation practices are applied. Use of plant cover

or crop residue provides protection from the impact of

raindrops and irrigation water from sprinkler systems

and prevents the loss of both soil and water from

runoff.

The effects of erosion can be very dramatic or very

subtle. Losses can be incurred at the source of the

erosion, over the area where the material is

transported, or at the area where the material is

deposited. Erosion results in loss of organic matter, a

breakdown of the natural soil structure, and alteration

of the soil texture through the loss of silt and clay, all of

which lead to degradation of the soil tilth and

workability.

Loss of plant nutrients and soil particles impairs the

productivity of soil. The severity of the erosion

determines how much productivity is lost and for how

long. The soil resource cannot be renewed through

natural processes in a short period of time. Many

years to hundreds of years may be required to replace

a part of the eroded surface layer, although cultural

practices and additions of soil amendments such as

manure may hasten the renewal of the soil. Soil

particles, nutrients, and chemicals carried by water

into streams and ponds may result in excessive plant

and animal growth, and the demand for oxygen may

be too high for some organisms to survive. The

turbidity of rivers and streams may be increased by

erosion, and domestic water supplies may be

contaminated or degraded as a result. Deposition of

soil material may destroy the spawning beds of

anadromous fish. Removal of sediment from irrigation

ditches, drainage ditches, and ponds is costly.

For each kind of soil and each kind of crop grown,

specific practices need to be applied to keep the soil

loss at an acceptable level. Soil drainage is a concern

for both fine textured and coarse textured soils. A

seasonal high water table can restrict the choice of

crops and the selection of management practices. The

soils in this survey area that have a seasonal high

water table include those of the Brenner,

Carpenterville, Chismore, Chitwood, Clawson,

Crofland, Euchre, Gleneden, Grindbrook, Heceta,

Loneranch, McCurdy, Nestucca, Quosatana, Selmac,

Wadecreek, Yaquina, and Zyzzug series. Restricted

drainage is primarily a result of the topography and the

internal characteristics of the soil. Drainage problems

may be compounded by inefficient irrigation systems.

The shape of the natural landscape affects the flow of

water. The water concentrates in certain areas,

causing saturation of the soils for varying lengths of

time. Unless the soils are artificially drained, the root

zone may become waterlogged for long periods and

the roots of crops may not get enough oxygen. Soil

characteristics such as a dense clay layer or

cemented iron pan restrict the movement of water.

This results in a seasonal high water table and limited

rooting depth. The Cashner, Chetco, Cove, Depoe,

Hebo, Hooskanaden, Houstenader, Huffling, Etelka,

Joeney, Langlois, Nelscott, Pyburn, and Whobrey soils

exhibit these characteristics.

Drainage can be improved in most areas by

installing surface or subsurface drainage systems.

Surface systems include use of diversions, open

drainage ditches, grassed waterways, and

impoundments and use of land shaping to eliminate

depressional areas. Subsurface systems include use

of plastic corrugated pipe or clay drainage tiles.

The survey area is not well suited to the production

of most row crops. In most areas, the soils warm up

slowly in spring and early in summer because of

wetness, prevailing northwesterly winds, and frequent

cloud cover. Fog and high humidity in coastal areas

prevent the accumulation of sufficient growing degree

days to allow for maturity of most row crops and small

grain used as forage. Some interior valleys receive

enough sunlight and have temperatures high enough

for corn to mature for use as silage; however, the

areas are of very limited extent and yields are limited.

The climate of the inland valleys is suitable for
Curry County, Oregon 307

cool-season crops; however, lack of suitable markets

makes production of such crops uneconomical.

According to the 1992 Census of Agriculture

(USDC 1993), Curry County had a total of 50,913

acres of pastureland. Of this, about 11,200 acres were

on flood plains, 12,805 acres were on terraces, and

26,908 acres were on hillsides. In 1992, 410 acres of

cranberries were harvested and about 497 acres were

used for horticultural and floricultural crops. About

2,711 acres of agricultural land were under irrigation.

A total of 7,136 acres were used as cropland that year,

of which 1,807 acres were used for crops such as hay

and small grain for silage or forage and for horticultural

and floricultural crops, 4,877 acres were used only for

pasture and grazing, and 452 acres were used for

vegetables and orchards. Curry County ranked first in

Oregon in the production of lily bulbs and second in

the production of cranberries (USDC 1993).

The soils and climate of the survey area are

excellent for forage production. The growing season is

long, and the soils receive sufficient moisture except

during July and August when rainfall seldom exceeds

0.5 inch per month. Irrigation is needed during this

period for maximum production.

Hayland and pastureland in the survey area can be

divided into three types—poorly drained and very

poorly drained soils on flood plains and lowlands, well

drained to poorly drained soils on flood plains and

terraces, and well drained and moderately well drained

soils on hillsides.

The poorly drained and very poorly drained areas

consist of soils such as those of the Brenner, Chetco,

Langlois, and Willanch series. These soils make up

about 3,800 acres of pastureland and hayland, or

about 7.5 percent of the total in the survey area. These

soils are mainly in a coastal strip between Port Orford

and the Coos County line, west of U.S. Highway 101.

Frequent, prolonged periods of flooding in winter

restrict the choice of pasture grasses to those that can

withstand inundation. Use of open ditches is the most

effective method of removing standing water from

these areas. Tidegates are needed in some areas to

prevent the inundation of saltwater during high tides.

These soils generally are too wet to allow for more

than one cutting of hay. The quality of the hay

generally is very poor because the high soil moisture

and high humidity prevent rapid drying of the hay. The

soils do not dry out enough to permit cutting until after

the grass has reached maturity. The quality of the hay

can be improved by grazing the hayfields until early in

June to delay cutting until the weather conditions are

more favorable.

The soils on flood plains and terraces are suited to

grass-legume pasture. These soils are mainly along

the major rivers and streams, such as the Chetco and

Winchuck Rivers in the southern part of the survey

area, the Pistol and Rogue Rivers in the central part,

and the Elk and Sixes Rivers and Floras Creek in the

northern part. The Bagness, Chetco, Kirkendall,

Nehalem, Nestucca, and Yachats soils are on flood

plains and are subject to frequent, long periods of

flooding in winter. As a result, use of the pastureland is

limited to brief periods. Maintaining a plant cover on

these soils in winter helps to reduce soil loss as a

result of flooding. These soils make up about 7,400

acres of pastureland and hayland, or about 14.5

percent of the total in the survey area. The Bullards,

Eilertsen, Ettersburg, Logsden, McCurdy, Meda,

Quillamook, and Zyzzug soils are on terraces. These

soils make up about 12,805 acres of pastureland and

hayland, or about 25 percent of the total in the survey

area. Open ditches are needed on the Zyzzug soils

because of the clayey subsoil.

Most of the hay harvested in the survey area is

grown on the soils on flood plains and terraces. The

well drained Bagness, Bullards, Ettersburg, Kirkendall,

Logsden, Meda, Nehalem, and Quillamook soils dry

out early enough to permit harvesting of hay at the

optimum stage of growth; however, the quality of the

hay generally is poor because of the heavy dew, fog,

and frequent rainshowers.

Irrigation is needed on most of the hayland in the

survey area because of the lack of adequate rainfall

during the growing season. In summer, droughtiness

limits the choice and production of forage plants. When

determining the most suitable irrigation method,

important factors to consider are the available water

capacity and water intake rate of the soils, the needs

of the crop grown, the natural subirrigation of soils that

have a high water table, and the availability of water for

irrigation.

The available water capacity is the amount of water

a soil can store for use by plants. Factors that affect

the ability of a soil to store water are depth, soil

texture, content of rock fragments, and content of

organic matter.

The water intake rate is determined by the soil

texture and structure and the content of organic

matter. Sandy soils absorb water rapidly and have a

low available water capacity while clayey soils absorb

water slowly and have a relatively high available

water capacity. Water moves through soils that have

good structure at a more desirable rate than it does

through soils that have poor structure.

Crops need water at critical periods for maximum

quality and production. To maintain desirable growth

rates, adequate moisture must be available to crops.

The number of acres irrigated depends on the amount
308 Soil Survey of

of water stored in the soils and the streamflow, which

generally are at minimum levels in summer.

The availability of water is dependent on the

competitive demands of agriculture, industry,

recreation, wildlife, and local communities. Irrigation

systems need to be designed so that all of the water

applied is used efficiently. Runoff or drainage water

can be filtered, collected, and reused.

Sprinkler systems are an efficient method of

applying water. They are the most common irrigation

method used in the survey area. These systems

should be designed to meet the needs of the specific

crop grown and the soil. Sprinkler systems can be

adapted to the slope, water intake rate, and crop

grown; therefore, water is applied more evenly and

precisely with these systems than with other irrigation

systems. The amount of water applied should be

adjusted to the water intake rate to prevent excessive

runoff and leaching of plant nutrients. Because soils

such as those of the Bigriver, Bullards, Gauldy, and

Yachats series are droughty as a result of the sandy

texture, applications of irrigation water on these soils

should be light and frequent. In some areas of the

Meda and Orford soils, irrigation may be impractical

because of the steepness of slope and lack of an

adequate water supply.

The soils on hillsides are suited to grass-legume

pasture. These soils make up about 26,908 acres of

pastureland, or about 53 percent of the total acreage

used as pastureland and hayland in the survey area.

These soils are mainly in two areas within the survey

area. The Burnthill, Grassyknob, Hooskanaden,

Loneranch, Reedsport, Reinhart, Svensen, Templeton,

Wedderburn, and Zwagg soils are on the coastal hills,

and the Barkshanty, Carpenterville, Edson, Etelka,

Hazelcamp, Houstenader, McDuff, Orford, Remote,

Skookumhouse, and Whobrey soils are on the interior

hills. To provide forage for use in winter, all of these

soils commonly are seeded to pasture mixtures of

subterranean clover, New Zealand white clover, and

improved grasses such as perennial ryegrass and

orchardgrass. Forage production is low in summer

because of droughtiness. Irrigation generally is not

practical because of the steepness of slope and lack

of an adequate water supply.

Using a good fertilization program that is based on

soil tests and includes applications of nitrogen,

phosphorous, potassium, sulfur, and molybdenum

fertilizers increases the production of forage plants.

Fertilizer is needed to ensure optimum growth of

grasses and legumes and to replace or supplement

the elements in the soil that are required for plant

nutrition. Generally, when fertilizer is added to soil it is

used by the crop grown, becomes part of the soil, is

leached downward by drainage water, is washed

away by erosion, or volatilizes and escapes as a gas,

as in the case of nitrogen and sulfur. To a significant

extent, nitrogen is the only element in fertilizer that is

affected by all of these processes. All forms of

nitrogen can be converted to nitrate nitrogen, which is

used by plants. In this form it moves freely in water

and is held weakly, or not at all, by soil particles.

Nitrogen should be applied in amounts adequate for

plant growth but not in amounts that can cause

excessive growth.

The effect of phosphorus on a soil sharply

contrasts that of nitrogen. When phosphates are

applied, they react rapidly to form many new

compounds. Phosphates generally are immobile in

the soil; therefore, they stay where placed unless they

are washed away by erosion.

When sulfur is applied to well drained soils, it can

be absorbed by the soils, leached by drainage water,

or used by plants. When it is added to poorly drained

soils, it can be converted to a gas and lost to the

atmosphere.

Molybdenum is a necessary micronutrient in soils

that is relatively unavailable to plants, although its

availability is known to increase as soil reaction (pH)

increases. Because movement of molybdenum is

limited, it should be applied so that it has widespread

contact with the soil. There is a very narrow range

between deficiency and toxicity of molybdenum.

Most of the soils used for hay and pasture are

strongly acid or very strongly acid unless lime is

applied. Some of the poorly drained soils on flood

plains are slightly acid or moderately acid. Application

of ground limestone is desirable in some areas to raise

the reaction (pH) of the soils and thus improve the

availability of certain nutrients, but it may not be

economically feasible.

The level of available phosphorus and molybdenum

is low in the upland soils. Pasture grasses and

legumes on the soils on flood plains and terraces

respond to phosphorus and sulfur. Pasture grasses

respond to nitrogen.

A cover of permanent pasture and proper grazing

management practices help to maintain a high content

of organic matter in the soils. Use of organic material

such as animal manure, plant refuse, and compost is

beneficial in maintaining and improving soil

productivity and promoting more rapid drainage and

warming of the soil. Adding organic matter to coarse

textured soils helps to retain moisture and plant

nutrients. Adding organic matter to fine textured soils

improves the workability, water intake rate, structure,

and aeration of the soils. Supplies of organic matter

commonly are adequate for home or specialty
Curry County, Oregon 309

gardens, but they are limited for large-scale

commercial production.

Management of livestock use on pastures is very

important for maintaining the long-term productivity of

the soils. Proper stocking rates, pasture rotation, and

restricted grazing during wet periods help to keep the

pastures in good condition and protect the soils from

compaction and erosion. Rotational grazing increases

the production of forage and helps to control weeds

and brush.

The major horticultural crops grown in the survey

area are Easter lily bulbs, cranberries, and

hydrangeas. Small amounts of blueberries and flowers

for cutting are also produced.

According to the 1992 Census of Agriculture,

cranberries from the survey area accounted for 27

percent of the total production in Oregon. About 410

acres were harvested in 1992 with a yield of 189

barrels per acre. The cranberry beds are dominantly

between Port Orford and Langlois, in the northern part

of the area.

Level areas for construction of beds, a source of

sand for the beds, a source of water for irrigating and

harvesting, and water conservation systems are

needed for cranberry production. Irrigation and

drainage are needed if the soils are intensively

managed for cranberries. Soils used for cranberries

include those of the Bandon, Bullards, Depoe, and

Nelscott series.

Cranberry beds are prepared by temporarily

removing the soil material above the restrictive

cemented iron pan. The subsurface area is then

leveled to remove woody material such as tree stumps

and brush. The surface soil, which contains higher

amounts of organic matter, is backfilled over the

subgrade. Generally, about 4 to 6 inches of soil

material containing organic matter is needed to seal

the subgrade. A least 2 inches of sand is then applied

over the base grade, and it commonly is crowned

slightly in the center of the bed to facilitate surface

drainage. The top of the cemented layer should be

graded toward the edge of the bed to provide for good

surface drainage. Cranberries are shallow-rooted, and

they do not tolerate wet conditions during the growing

season. Open ditches and dikes are needed around

the edges of bed to provide drainage and to control

the water level at harvest time.

Sprinkler irrigation is an efficient method of

applying water during the dry period in summer

(fig. 10). Sprinklers can also be used to control the

temperature in summer and to protect the buds and

blooms from frost damage in spring.

310 Soil Survey of

The very slow permeability of the cemented layer

facilitates water management by preventing excessive

seepage and minimizes loss of fertilizer and soil

amendments. Excessive seepage may occur,

however, in the sandy substratum of the soils.

The soils and climate in the Brookings-Harbor

Bench area are suitable for lily bulb production

(fig. 11). In 1993, about 500 acres were planted to lily

bulbs. Lilies are grown mainly on Harbor Bench, but

minor amounts are grown along the stream terraces of

the Winchuck River. The Crofland, Ettersburg, Huffling,

Klooqueh, and Winchuck soils are suited to growing

lilies. The survey area supplies 100 percent of the lily

bulbs used in the United States and Canada for

Easter. Depending on the level of management,

commercial yields range from about 52,000 to 78,000

bulbs per acre.

Irrigation and drainage are needed if the soils are

intensively managed for production of lily bulbs.

Irrigation is needed in summer on all of the soils.

Sprinkler irrigation is an efficient method of applying

water. Application rates should be adjusted to the

permeability or water intake rate of the soils to avoid

excessive runoff and leaching of plant nutrients.

Drainage is needed for maximum production on the

Crofland and Huffling soils.

Lily bulbs have a 2- to 3-year production cycle.

Pieces of bulbs, or scales, are planted in August,

dug up the following fall (mid-August to early in

November), and replanted as bulblets in another

field. The bulblets are left to grow during the second

year and then are dug up as yearlings the following

fall. They are then planted in another field that has

been used to grow perennial cover crops for 3 or 4

years. The bulbs grow to commercial size by fall

of the third year. They are then graded, or sized,

and the merchantable ones are packed in boxes

with peat moss and shipped to commercial

greenhouses. There they are potted, and by

controlling the temperature, they are forced to bloom

by Easter.

Field operations for bulb production include plowing

and discing several times to prepare the planting beds.

Weeds are controlled through a combination of

mechanical and chemical operations. Lily fields are

rotated to perennial pasture for 3 or 4 years after a

single year of bulb production. The fields are planted

to a variety of improved grasses, such as perennial

ryegrass, to control soil erosion, maintain organic

matter content, and maintain aeration by improving

soil structure and tilth.

The major concern in producing lily bulbs is control

of undesirable fungi, viruses, and nematodes. Fungi

and viruses reduce the quality and marketability of the

bulbs, and nematodes destroy the plant roots by

turning them yellow, then brown, and finally black and

hollow. Growers use a 2-step chemical process to

achieve acceptable control of nematodes. First,

fumigants are applied to the soil in summer before the

bulbs are planted in fall, and then insecticides are

applied in the furrow when the bulbs are planted. For

environmental reasons, growers currently are testing

several different alternatives to chemical fumigation

and a few options appear to have good potential for

use in the future.

On all of the soils in the survey area, additions of

lime, fertilizer, or other amendments should be based

on the results of soil tests, on the needs of the crop

grown, and on the expected yields. The Cooperative

Extension Service can help in determining the kinds

and amount of fertilizer, lime, and other soil

amendments to apply. The latest information on

adapted varieties and seeding recommendations can

be obtained from the local office of the Cooperative

Extension Service and the Natural Resources

Conservation Service.

The management systems needed to achieve high

yields and top-quality crops vary depending on the

kind of soil and the kind of crop grown. Applying

management practices designed for specific crops and

soils is essential for obtaining sustained high yields.

Information on resource management systems and

practices and on design of irrigation systems is

available at the local office of the Natural Resources

Conservation Service.

Yields per Acre

The average yields per acre that can be expected

of the principal crops under a high level of

management are shown in table 5. In any given year,

yields may be higher or lower than those indicated in

the table because of variations in rainfall and other

climatic factors.

The yields are based mainly on the experience and

records of farmers, conservationists, and extension

agents. Available yield data from nearby counties and

results of field trials and demonstrations are also

considered.

The management needed to obtain the indicated

yields of the various crops depends on the kind of soil

and the crop. Management can include drainage,

erosion control, and protection from flooding; the

proper planting and seeding rates; suitable highyielding crop varieties; appropriate and timely tillage;

control of weeds, plant diseases, and harmful insects;

favorable soil reaction and optimum levels of nitrogen,

phosphorus, potassium, and trace elements for each

crop; effective use of crop residue, barnyard manure,

and green manure crops; and harvesting that ensures

the smallest possible loss.

For yields of irrigated crops, it is assumed that the

irrigation system is adapted to the soils and to the

crops grown, that good-quality irrigation water is

uniformly applied as needed, and that tillage is kept to

a minimum.

The estimated yields reflect the productive capacity

of each soil for each of the principal crops. Yields are

likely to increase as new production technology is

developed. The productivity of a given soil compared

with that of other soils, however, is not likely to

change.

Crops other than those shown in table 5 are grown

in the survey area, but estimated yields are not listed

because the acreage of such crops is small. The local

office of the Natural Resources Conservation Service

or of the Cooperative Extension Service can provide

information about the management and productivity of

the soils for those crops.

Land Capability Classification

Land capability classification shows, in a general

way, the suitability of soils for most kinds of field crops.

Crops that require special management are excluded.

The soils are grouped according to their limitations for

field crops, the risk of damage if they are used for

crops, and the way they respond to management. The
312 Soil Survey of

criteria used in grouping the soils do not include major

and generally expensive landforming that would

change slope, depth, or other characteristics of the

soils, nor do they include possible but unlikely major

reclamation projects. Capability classification is not a

substitute for interpretations designed to show

suitability and limitations of groups of soils for

woodland and for engineering purposes.

In the capability system, soils are generally grouped

at three levels—capability class, subclass, and unit

(USDA, 1961). Only class and subclass are used in

this survey.

Capability classes, the broadest groups, are

designated by numerals I through VIII. The numerals

indicate progressively greater limitations and narrower

choices for practical use. The classes are defined as

follows:

Class I soils have few limitations that restrict their

use.

Class II soils have moderate limitations that reduce

the choice of plants or that require moderate

conservation practices.

Class III soils have severe limitations that reduce

the choice of plants or that require special

conservation practices, or both.

Class IV soils have very severe limitations that

reduce the choice of plants or that require very careful

management, or both.

Class V soils are not likely to erode but have other

limitations, impractical to remove, that limit their use.

Class VI soils have severe limitations that make

them generally unsuitable for cultivation.

Class VII soils have very severe limitations that

make them unsuitable for cultivation.

Class VIII soils and miscellaneous areas have

limitations that nearly preclude their use for

commercial crop production.

Capability subclasses are soil groups within one

class. They are designated by adding a small letter,

e, w, s, or c, to the class numeral, for example, IIe.

The letter e shows that the main hazard is the risk of

erosion unless close-growing plant cover is

maintained; w shows that water in or on the soil

interferes with plant growth or cultivation (in some

soils the wetness can be partly corrected by artificial

drainage); s shows that the soil is limited mainly

because it is shallow, droughty, or stony; and c,

used in only some parts of the United States, shows

that the chief limitation is climate that is very cold or

very dry.

In class I there are no subclasses because the soils

of this class have few limitations. Class V contains only

the subclasses indicated by w, s, or c because the

soils in class V are subject to little or no erosion. They

have other limitations that restrict their use to pasture,

rangeland, woodland, wildlife habitat, or recreation.

The capability classification of the map units in this

survey area is given in table 5.

Prime Farmland

Prime farmland is one of several kinds of important

farmland defined by the U.S. Department of

Agriculture. It is of major importance in meeting the

Nation’s short- and long-range needs for food and

fiber. Because the supply of high-quality farmland is

limited, the U.S. Department of Agriculture recognizes

that responsible levels of government, as well as

individuals, should encourage and facilitate the wise

use of our Nation’s prime farmland.

Prime farmland, as defined by the U.S. Department

of Agriculture, is land that has the best combination of

physical and chemical characteristics for producing

food, feed, forage, fiber, and oilseed crops and is

available for these uses. It could be cultivated land,

pastureland, forest land, or other land, but it is not

urban or built-up land or water areas. The soil qualities,

growing season, and moisture supply are those

needed for the soil to economically produce sustained

high yields of crops when proper management,

including water management, and acceptable farming

methods are applied. In general, prime farmland has

an adequate and dependable supply of moisture from

precipitation or irrigation, a favorable temperature and

growing season, acceptable acidity or alkalinity, an

acceptable salt and sodium content, and few or no

rocks. It is permeable to water and air. It is not

excessively erodible or saturated with water for long

periods, and it either is not frequently flooded during

the growing season or is protected from flooding. The

slope ranges mainly from 0 to 6 percent. More detailed

information about the criteria for prime farmland is

available at the local office of the Natural Resources

Conservation Service.

Only 1,064 acres in the survey area, or about 0.1

percent of the total acreage, meets the soil

requirements for prime farmland. The scattered areas

are on stream terraces along the Rogue and Illinois

Rivers, in the central interior of the survey area. These

areas are in general soil map unit 16, which is

described under the heading “General Soil Map Units.”

The map units in the survey area that are

considered prime farmland are listed in table 6. This

list does not constitute a recommendation for a

particular land use. On some soils included in the list,

measures that overcome a hazard or limitation, such

as flooding, wetness, and droughtiness, are needed.

Onsite evaluation is needed to determine whether or

not the hazard or limitation has been overcome by
Curry County, Oregon 313

corrective measures. The extent of each listed map

unit is shown in table 4. The location is shown on the

detailed soil maps. The soil qualities that affect use

and management are described under the heading

“Detailed Soil Map Units.”

Forestland Management and Productivity

By Craig M. Ziegler, forester, Natural Resources Conservation

Service.

Curry County is one of the primary producers of

timber in southwestern Oregon. The best timbergrowing sites are in areas of soils that are derived

from late Jurassic sedimentary and volcanic rock of

the Dothan Formation, are at middle and lower

elevations, and support the Sitka spruce cover type

and in areas of deep sedimentary soils that support

the Pacific Douglas fir and Douglas fir/Tanoak/Pacific

madrone cover types. The higher elevations are too

cold to produce large quantities of timber. About 90

percent of the county is classified as commercial

forestland. Of this, about 20 percent is owned by the

forest industry, 4 percent is owned by small woodland

operators, and 66 percent is publicly owned and is

managed by the Forest Service and Bureau of Land

Management.

The towns of Brookings and Gold Beach are

recognized as the centers of the forest products

industry in the survey area. The Forest Service,

Oregon State Department of Forestry (Coos Forest

Protection Association), and local fire districts provide

protection from fire.

The principal forest cover type is the Douglas fir/

Tanoak/Pacific madrone type (Eyre 1980). This cover

type is in an area about 2 miles east of the Pacific

Ocean and is outside the influence of the coastal

fogbelt. The dominance of either Douglas fir or tanoak

in the overstory depends on past disturbances and the

presence or absence of a seed source for Douglas fir.

Tanoak is a unique tree species because it can

resprout and grow vigorously after fire or logging and

can grow in shade under a canopy of Douglas fir.

Unless mature Douglas fir trees are nearby to provide

a seed source, tanoak will become dominant after a

disturbance.

Within the Douglas fir/Tanoak/Pacific madrone

cover type are areas of the Jeffrey pine cover type

(Eyre 1980). This type is mainly associated with

serpentine-influenced soils. These soils have a

calcium/magnesium imbalance and are high in content

of toxic heavy metals, such as nickel and chromium,

which limit productivity. Generally, these soils support

dominantly Jeffrey pine but Douglas fir, Port Orford

cedar, western white pine, and incense cedar can also

be present. This cover type has the most diverse

composition of shrubs, forbs, and grasses in the

survey area.

The Sitka spruce cover type covers an area about

1 to 2 miles wide along the coastal zone (Eyre 1980).

Sitka spruce is dominant in this area, but occasional

western hemlock, Douglas fir, grand fir, and shore

pine trees are present. Repeated fires in this area

resulted in the establishment of open areas of

grassland within the forests. Many of these areas are

converting back to the Sitka spruce cover type as a

result of about 50 years of fire-control activities.

Red alder is the major seral tree species in this area.

Because it is very competitive, it will take over

disturbed areas unless they are planted to spruce or

Douglas fir.

South of the Chetco River is the northernmost

extension of the Redwood cover type (Eyre 1980).

Redwood is a major component of the overstory;

however, large amounts of Douglas fir and tanoak are

also present. North of Sisters Rock is a climatic

change to more moist marine air and cooler

temperatures. Western hemlock and Port Orford cedar

start to occur within the Sitka spruce cover type in this

area and in the Pacific Douglas fir cover type in inland

areas.

North of Sisters Rock is the western hemlock cover

type (Eyre 1980). Western hemlock generally is the

dominant tree in older, undisturbed stands. In

disturbed stands, Douglas fir can be mixed with

western hemlock or it can be dominant. Other tree

species in this cover type are grand fir, Port Orford

cedar, tanoak, red alder, and in very moist areas,

western redcedar.

The White fir and Red fir cover types are in inland

areas at the highest elevations (Eyre 1980). In the

White fir cover type, white fir and Douglas fir are

dominant. Shasta red fir is also present, and it

increases in abundance as elevation increases. The

Red fir cover type is comprised of a mixture of Shasta

red fir, white fir, and Douglas fir. Depending on past

disturbances, any one of these species can be

dominant.

The major forest management concerns in the

survey area are brush competition, seedling mortality,

soil erosion, equipment limitations, windblast, and soil

compaction. The two major hardwood species, red

alder and tanoak, are severe competitors to the

establishment of Douglas fir. Thorough site

preparation followed by prompt reforestation is

essential for Douglas fir seedlings to become

established. Mechanical or chemical treatment also

may be necessary to control competition from

hardwood species.
314 Soil Survey of

Even though the survey area receives 90 to 160

inches of precipitation annually, seedling mortality can

be severe in areas of the Douglas fir/Tanoak/Pacific

madrone cover type on the hot, dry, south-facing

slopes. The success of the reforestation can be

enhanced by planting early in winter, planting highquality nursery stock adapted to the climatic zone, and

using shade devices to reduce heat and moisture

stress in the seedlings.

Windblast can greatly reduce the productivity of

Sitka spruce and Douglas fir stands growing on the

side slopes of coastal terraces and uplands that are

exposed to ocean winds. Intermediate harvest cuttings

are not recommended because of the increased

potential for windthrow.

Most of the forested areas in the survey area have

slopes of more than 40 percent. Exposing the soil

during forest management activities greatly increases

the risk of erosion. Proper harvesting techniques

adapted to the specific soil conditions are essential.

Properly designing and locating roads; revegetating

landings, skid trails, and spur roads; and maintaining

stream buffer strips are essential to minimize erosion

and sedimentation of streams. Seeding of cuts and fills

and proper placement of culverts, road drains, and

water bars are also essential.

Soil compaction can reduce timber production by

limiting the movement of air and water in the soil, thus

restricting the growth of roots. To minimize soil

compaction and displacement, avoid the use of

equipment when the soils are wet and use harvesting

systems that fully or partially suspend logs above the

soil surface. When using ground-based equipment, a

well-planned system of skid trails can minimize the

amount of soil subject to compaction and

displacement.

The majority of the forestland in the survey area

provides forage for wildlife. The amount of forage

available under many timber stands is low, however,

and the palatability of the plants ranges from low to

high.

The forested areas in the survey area are affected

by many diseases and insects that may present

problems in individual stands of trees. Damage can

vary from year to year.

The principal insect that attacks Douglas fir is the

Douglas fir beetle (dendroctonus pseudotsugae).

Laminated root rot (phylinius weiril) is a fungus that

easily kills Douglas fir by attacking the root system.

Black stain root disease (ceratocystis wageneri) is

increasing in occurrence, particularly in Douglas fir

plantations. The Sitka spruce weevil (dissodes

sitchensis) kills the terminal shoots of spruce and

along with the spruce aphid (aphis abientina) causes

the most damage to Sitka spruce. Port Orford cedar is

readily attacked by cedar root rot (phytophthora

lateralis), endangering the species. White pine blister

rust (cronartium ribicola), a disease that attacks and

kills five-needle pines, can infect western white pine

and sugar pine if the alternate host species is present.

Soil surveys are important to forestland managers

as they seek ways to maximize the use of forestland.

Certain soils respond better to fertilization, some are

susceptible to landslides and erosion after

roadbuilding and harvesting, and others require

special practices to harvest and reforest.

In the section “Detailed Soil Map Units,” information

about productivity and management is given for each

map unit in the survey area that is suitable for

producing timber. In table 7, the soils are rated for a

number of factors considered in forestland

management. “Slight, moderate,” and “severe” indicate

the degree of the major soil limitation considered in

management.

Sheet and rill erosion hazard refers to the

probability of excessive erosion occurring as a result

of operations that expose the soil. Forested areas that

have been affected by fire or overgrazing are also

subject to erosion. A rating of slight indicates that no

particular erosion-control measures are needed under

ordinary conditions, moderate indicates that some

erosion-control measures are needed, and severe

indicates that extra precautions are needed to control

erosion during most silvicultural activities.

Erosion hazard ratings are determined by

considering the topography, the erodibility of a soil,

and the local climate. A rating of moderate or severe

may indicate the need for modified road construction,

special harvesting systems, and alternative site

preparation techniques.

Cut and fill slope erosion hazard refers to the

probability that damage may occur as a result of

erosion from road cuts and fills. Seeding of cut and fill

slopes is always recommended. A rating of slight

indicates that no other preventative measures are

needed under ordinary conditions, moderate indicates

that additional erosion-control measures such as

mulching and using sediment traps are needed under

certain conditions, and severe indicates that additional

erosion-control practices are needed under most

conditions.

The texture of the surface and subsurface layers

and the angle and length of the slope contribute to the

risk of cut and fill slope erosion. The risk of erosion

becomes higher as the length of the cut and fill slope

increases and as the erodibility of the soil increases.

Equipment limitation describes the restrictions on

the use of equipment as a result of soil characteristics.
Curry County, Oregon 315

A rating of slight indicates that equipment use

normally is not restricted because of soil factors,

moderate indicates a short seasonal limitation

because of soil wetness, a fluctuating water table, or

some other factor, and severe indicates a seasonal

limitation, a need for special equipment, or a hazard in

the use of equipment.

Steepness of slope, soil wetness, and the

susceptibility of the soil to compaction are the main

factors that result in equipment limitations. As the

gradient and length of the slope increase, it becomes

more difficult to use wheeled equipment. On the

steeper slopes, tracked equipment should be used,

and on the steepest slopes, cable yarding systems

should be used. Soil wetness, especially in areas

where the soil material is fine textured, can severely

limit the use of equipment and make harvesting

practical only during the dry period in summer.

Soil compaction refers to the probability that

damage to the soil structure will occur as a result of

repeated equipment use during periods when the soil

is wet or moist. Compaction should always be

considered during silvicultural activities. A rating of

slight indicates that no extra precautions are needed,

but use of designated skid trails and protection of the

duff layer is advised; moderate indicates a potential

need for extra precautions such as use of cable

yarding systems instead of ground-skidding equipment

and seasonal restrictions on equipment use; and

severe indicates the need for extreme caution and

possibly some restorative measures such as ripping or

discing following harvesting.

Thickness of the layer of duff, content of coarse

fragments, texture, and plasticity are soil

characteristics considered in the soil compaction

ratings. The ratings assume that the soil is wet or

moist. Soil compaction decreases air spaces in the

soil; thus, the movement of air and water is reduced,

restricting root growth and increasing the risk of

surface erosion.

Soil displacement refers to the risk of soil being

gouged, scraped, or pushed from its natural position

by mechanical means. It is most often associated with

mechanical slash disposal and site preparation. A

rating of slight indicates that equipment use is not

restricted and that special precautions generally are

not needed; moderate indicates that use of specialized

equipment, such as a brush rake, is recommended;

and severe indicates that use of extreme caution is

advised if mechanical methods of slash disposal and

site preparation are used.

Thickness of the layer of duff, thickness of the

surface layer, content of coarse fragments, and texture

are soil characteristics considered in the soil

displacement ratings. Removing or mixing the layer of

duff and exposing the mineral soil are necessary for

natural regeneration of many species; however, plant

recovery rates may be impaired if excessive soil

displacement has occurred. Prolonged exposure of

barren soil may result in an increased risk of erosion

and further deterioration of the site.

Seedling mortality refers to the probability of death

of tree seedlings as a result of soil or topographic

conditions. Plant competition is not considered in this

rating. The ratings apply to healthy, dormant seedlings

from good stock that are properly planted during a

period of sufficient moisture. Slight indicates that

mortality is not expected to be a problem under normal

conditions, moderate indicates some mortality can be

expected and that extra precautions are advisable,

and severe indicates that mortality will be high and

extra precautions are essential for successful

reforestation.

Soil wetness, droughtiness, and topographic

conditions affect seedling mortality. Larger than normal

planting stock, special site preparation, surface

drainage, or reinforcement plantings may be needed.

Windthrow hazard rates the likely development of

tree roots and the ability of the soil to hold trees firmly.

A rating of slight indicates that trees normally are not

blown down by the wind, moderate indicates that an

occasional tree may be blown down during periods

when the soil is wet and winds are moderate or strong,

and severe indicates that many trees may be blown

down during periods when the soil is wet and winds

are moderate or strong.

Restricted rooting depth because of a high water

table, underlying bedrock, or an impervious layer and

poor anchoring of roots because of loose soil material

affect the risk of windthrow. A rating of moderate or

severe indicates a need for care in thinning forest

stands, periodic salvage of windblown trees, and an

adequate system of roads and trails to allow for

salvage operations.

Plant competition refers to the likelihood of the

invasion of undesirable plants when openings are

made in the tree canopy. A rating of slight indicates

that unwanted plants are not likely to retard the

development of natural or planted reforestation,

moderate indicates that competition will retard natural

or planted reforestation, and severe indicates that

competition can be expected to prevent natural or

planted reforestation.

Favorable climatic conditions and favorable soil

characteristics contribute to plant competition

problems. In many areas, the key to predicting plant

competition problems is the quantity and proximity of

seed sources of undesirable plants or the quantity of
316 Soil Survey of

unwanted brush rootstock that will resprout after

harvesting. A rating of moderate or severe indicates

the need for careful and thorough site preparation and

the potential need for mechanical or chemical

treatment to retard the growth of competing

vegetation.

Fire damage refers to the probability that a fire of

moderate fireline intensity (116 to 520 BTUs per

second per foot) will have a negative impact on the

characteristics of a soil. A rating of slight indicates that

negative impacts to soil characteristics are not

expected, moderate indicates that negative impacts

such as nonwettability or excessive erosion may occur

and that extra caution is needed in planning

prescribed fires, and severe indicates that negative

impacts are likely to occur and that extreme caution is

advised in planning prescribed fires.

The thickness of the layer of duff, content of organic

matter, and texture are soil characteristics considered

in determining the ability of soil to resist fire damage. It

may be necessary to burn in winter, use alternative

lighting techniques, monitor the moisture content of

fuel, yard merchantable material, eliminate prescribed

fires, or apply erosion-control measures following

burning.

In table 8, the potential productivity of common

trees is expressed as a site index and volume number.

The site index is determined by measuring the height

and age of selected trees within stands of a given

species. The index is the average height, in feet,

attained by dominant and codominant trees of a given

species in a specified number of years. The procedure

for calculating site index is described in the

publications used for Douglas fir (King 1966, McArdle

and others 1961), redwood (Lindquist and Palley

1963), western hemlock (Barnes 1962, Wiley 1970),

grand fir and white fir (Schumacher 1926), Shasta red

fir (Schumacher 1928), Sitka spruce (Meyer 1937),

ponderosa pine and Jeffrey pine (Meyer 1938), and

sugar pine (Biging and Wensel 1984). The site index

applies to fully stocked, even-aged stands. The highest

timber yields can be expected from the soils that have

the highest site index values. Site index values can be

converted into estimated yields at various ages by

carefully using the appropriate yield tables. In table 8,

the trees are listed in the order of their general

abundance as observed on the soil.

To facilitate comparing the potential productivity of

different soils, the table includes values for potential

wood production expressed as total yield (board feet

per acre) and annual growth (cubic feet per acre).

Estimates of volume are calculated at the culmination

of the mean annual increment (CMAI). The annual

amount of wood fiber produced by a stand of trees

changes as the stand matures. Very little wood fiber is

produced when the trees are small, but the amount

increases rapidly as the trees approach physiological

maturity. Once trees reach maturity, the annual growth

rate begins to slow. CMAI is the estimated age at

which a fully stocked stand achieves its highest

average annual growth rate. It is the most efficient time

to harvest as far as tree growth is concerned. Other

factors, such as stumpage values, cost effectiveness,

and management objectives, also should be

considered in determining the best time to harvest.

As an example of how the table can be used,

consider the Cunniff soil in detailed soil map unit 70D.

A fully stocked stand of Douglas fir on this soil has a

site index of 148; that is, the average height of the

dominant and codominant trees at age 100 is 148 feet.

If the stand is allowed to grow for 100 years, the

predicted yield will be 70,500 board feet per acre.

However, the stand will attain its maximum annual

production of wood fiber (156 cubic feet per acre per

year) at age 60.

The species under common trees that are indicated

by a footnote notation are recommended for planting

and are most suitable for commercial wood

production.

Vegetative Diversity

By Gene Hickman, range conservationist, Natural Resources

Conservation Service.

Southwestern Oregon is a very diverse ecological

region. Vegetative diversity is primarily the result of

dramatic climatic gradients, such as the one between

the moist Pacific Coast and the high, cold Cascade

Mountains. Crossing this is a second regional climatic

gradient resulting from latitudinal changes north to

south between the mild Willamette Valley and the hot

Mediterranean climate of northern California. Because

of the mountainous topography, there are also

numerous localized climatic transitions that make

macroclimate relationships with vegetation and

landscapes even more complex.

In addition, a wide variety of soils and related

geologic features directly affect local plant distribution

and the resulting plant communities. Rock types such

as serpentinitic peridotite impact the chemical

properties of soils, which significantly affect the

production and composition of plants. Other

characteristics of importance to plant adaptation and

growth are soil depth, texture, and drainage and the

content of rock fragments. Together these either

restrict or facilitate vegetative development to the

extent possible under the prevailing climate.

Elevation, aspect, slope, and topography are other
Curry County, Oregon 317

landscape features that affect the local microclimate

and consequently affect plant cover. The vegetative

types in the drainageways and on the toeslopes above

the drainageways are suited to more moist conditions

than are those on the uplands. North-facing slopes

receive less direct sunlight and support plant

communities that are less tolerant of drought than do

south-facing slopes. At high elevations, all aspects

support species that are more tolerant of cold

temperatures. The elevational changes in vegetation

commonly correlate with differences in precipitation,

length of the growing season, snowfall, and

temperature. Latitude affects the elevation at which

these changes occur. Equivalent ecological changes

occur at much higher elevations moving north to

south. There is a similar elevational increase when

moving inland west to east, from the coastline to the

Cascade Mountains.

In southwestern Oregon, broad ecological

subdivisions have been recognized. These ecological

subdivisions are within the regional provinces defined

by Daubenmire (Daubenmire 1968) and are described

locally by Franklin and Dyrness (Franklin and Dyrness

1973). Franklin and Dyrness describe four

subdivisions characterized by Sitka spruce coastal

forests, western hemlock forests of both the Cascade

and Coast Ranges, mixed conifer-mixed evergreen

forests, and the interior valleys of the Rogue and

Umpqua Rivers.

The survey area spans three of these subdivisions

in addition to the climatic, geologic, topographic, and

edaphic features discussed previously. The landscape

and climatic features combine to create a wide variety

of contrasting environments with the potential to

support diverse native plant communities. These

communities are grouped into vegetative zones

representing major macroclimatic environments.

Vegetation zones may cover large geographic

areas, but they always have a single set of potential

native plant communities throughout. Vegetative

patterns commonly are predictable within the zones

because they are related to local landscape features

such as aspect, soil, and landform. The zones are

useful in focusing on geographic differences in

climate and vegetation and generalizing complex

local vegetation patterns. They also provide a basis

for broad management interpretations. The

vegetation zones in the survey area are described in

this section and are shown on the general vegetation

map.

Coastal Fog Zone

The Coastal Fog Zone parallels the Pacific Ocean

coastline in a belt ranging from 2 to 10 miles wide and

extending along all of the coastal river valley corridors.

The climate is very mild; it does not have the wide

extremes in temperature as does that of the inland

areas. The temperature is moderated by coastal fog,

frequent cloudy weather, and the ocean. The average

annual precipitation is about 70 to 95 inches, and the

elevation ranges from sea level to about 1,300 feet.

The soils have a udic moisture regime and an

isomesic temperature regime. This zone correlates

with general soil map units 1, 3, 4, 6, and 7.

The Coastal Fog Zone can be subdivided into two

parts that are oriented west to east and are based on

the prevalence of Sitka spruce. The western part of

this zone is adjacent to the ocean and is more affected

by marine fog and salt spray. It is comprised of

beaches, dunes, marine terraces, and west-facing

mountain fronts, which are those most exposed to the

coastal weather. It also extends inland along coastal

river valleys in areas not constrained by the

mountains. It supports shore pine and Sitka spruce

intermingled with Douglas fir, western hemlock, red

alder, California laurel, Pacific waxmyrtle, tanoak, and

cascara buckthorn. Understory species include Pacific

rhododendron, evergreen huckleberry, western

swordfern, salal, red elderberry, salmonberry, and

western dewberry.

The eastern part of this zone is comprised of

mountains and valleys farther inland that have less

exposure to coastal weather. The eastern part does

not support shore pine and supports fewer Sitka

spruce trees. The forests consist of Douglas fir, grand

fir, scattered Sitka spruce, and western hemlock with

hardwoods such as tanoak, red alder, bigleaf maple,

and cascara buckthorn. Port Orford cedar is in the

moist areas. The understory on both the north- and

south-facing slopes consists of very dense stands of

swordfern and shrubs.

The Coastal Fog Zone can also be subdivided into

two parts that are oriented north to south and are

based on topographic differences and the occurrence

of western hemlock. The northern part is north of

Humbug Mountain. Western hemlock is prevalent in

many stands of Sitka spruce and Douglas fir. In the

southern part, western hemlock occurs only in

localized areas, primarily on the eastern side. It is

present in areas such as Squaw Valley; along the

Rogue River, near Lobster Creek; and along the South

Fork of Hunter Creek.

The production of trees is high in the Coastal Fog

Zone. Dense stands of red alder regeneration occur in

the moist areas following disturbances such as fire or

timber harvesting. Tanoak is an aggressive hardwood

in the drier areas and on south-facing slopes. Tree

plantations are subject to severe plant competition

from hardwood trees and from evergreen and

deciduous shrubs.

Redwood Zone

The Redwood Zone in southwestern Oregon is the

northernmost extent of the redwood forests on the

Pacific Coast. It extends south along the California

coast to beyond San Francisco, although it is of limited

extent in this survey area. Similar to Sitka spruce,

redwood is associated with a very mild climate with

fog in summer and generally warm conditions. The

average annual precipitation is about 90 to 130 inches,

and the elevation ranges from 200 to 1,300 feet. The

soils have a udic moisture regime and an isomesic

temperature regime. This zone correlates with general

soil map units 2 and 5.

In Oregon, the Redwood Zone extends inland away

from the coast and north to the Chetco River, where

the zone becomes quite fragmented. The fragmented

redwood stands are only in very favorable locations.

The entire zone appears to be a transitional area

between the southern part of the Coastal Fog Zone

and the Coastal Tanoak Zone.

Redwood forest communities are characteristic of

this zone, and they include most of the species in the

Coastal Tanoak Zone. Stands of redwood are on all

aspects near the Oregon-California border, but they

progressively become less abundant and are only on

north aspects and in drainageways at the

northernmost limits of the zone.

The productivity of the forest is high in this general

vegetation zone because of the increased

atmospheric moisture, low evapotranspiration rate,

and long growing season. Intense competition from

tanoak, blueblossom ceanothus, evergreen

huckleberry, and other shrubs is a concern for

regeneration.

Coastal Tanoak Zone

The Coastal Tanoak Zone is the dominant

vegetative zone in the survey area. This zone is

confined to the western part of the Coast Range,

where marine influences have a strong effect on the

climate. Cloud cover occurs often enough in summer

to create a moderating effect on the temperature in

summer. The average annual precipitation is about 90

to 130 inches. Elevation ranges from about 200 to

2,200 feet in the northern part of the survey area to

3,000 feet in the southern part. The soils have a udic

moisture regime and a mesic temperature regime.

This zone correlates with general soil map units 10,

11, and 13.

The Coastal Tanoak Zone is best characterized by

mixed stands of Douglas fir and tanoak with Pacific

madrone, bigleaf maple, and California laurel in the

moist areas. Scattered minor areas of western

hemlock, Port Orford cedar, and golden chinkapin may

also be in this zone. Understory species include

tanoak, salal, Pacific rhododendron, evergreen

huckleberry, western dewberry, little wildrose, western

swordfern, and beargrass.

The Coastal Tanoak Zone is highly productive. A

major management concern is the severe competition

from tanoak after disturbances such as fire or timber

harvesting.

Interior Tanoak Zone

The Interior Tanoak Zone occurs only on the

eastern side of the survey area. It represents the

warmer and drier climatic zone of the Coast Range.

The soils in this zone are dry for longer periods of

time. The presence of more drought-tolerant species

separate this zone from the Coastal Tanoak Zone.

Together, the Interior Tanoak Zone and Coastal

Tanoak Zone represent the northernmost extent of a

large ecological zone that stretches south into

northern California.

The Interior Tanoak Zone is comprised of coastal

mountains. The average annual precipitation is 80 to

100 inches. Elevation generally is less than 3,000 feet.

The soils have a mesic temperature regime and a

xeric moisture regime. This zone correlates with

general soil map units 16, 17, and 18.

The Interior Tanoak Zone is characterized by an

abundance of tanoak trees on north aspects and

tanoak shrubs on south aspects, indicating the

dramatic environmental difference between the north

and south aspects. Douglas fir is the primary

associated tree species, and it commonly is dominant

in the stand. The species composition of this zone is

similar to that of the Coastal Tanoak Zone except for

sporadic occurrences of Pacific rhododendron and

Port Orford cedar. Also prevalent are sugar pine,

ponderosa pine, incense cedar, California black oak,

and canyon live oak. Grand fir, western redcedar, and

red alder commonly are absent. White alder instead of

red alder is present in some of the drainageways.

Golden chinkapin trees are on some of the north

aspects. Pacific madrone is more prevalent in this

zone than in the Coastal Tanoak Zone, especially on

south aspects.

The shrub cover in this zone includes fewer

evergreen species and more deciduous species than

in the Coastal Tanoak Zone, and it may include

cascade Oregongrape, salal, prince’s pine, and

evergreen huckleberry. Pacific poison oak and

canyon live oak trees and shrubs commonly are on

the south-facing slopes.
Curry County, Oregon 319

The Interior Tanoak Zone has a lower forest

productivity potential than does the Coastal Tanoak

Zone. Important forest management considerations

include a longer dry season, which greatly increases

the length and severity of the fire season, and the

competitive nature of aggressive hardwoods. Tanoak

and Pacific madrone readily sprout after disturbances

such as timber harvesting or fire. Canyon live oak is

more abundant and can even be codominant in the

forest stands in areas of soils that have a high content

of rock fragments.

Western Hemlock Zone

The Western Hemlock Zone is comprised of much

of the Coast Range. In this survey area, this zone

occupies the northernmost part of the county, in the

Floras Creek watershed, and scattered areas in the

northeastern part of the county. The average annual

precipitation is about 90 to 130 inches. Summer fog

and cloudy weather reduce evapotranspiration in this

zone. Elevation generally is less than 2,100 feet in the

northernmost part, but it ranges to 3,000 feet in the

northeastern part. The soils have a udic moisture

regime and a mesic temperature regime. This zone

correlates with general soil map unit 12 and areas of

units 10 and 13 in the northernmost part of the survey

area.

The Western Hemlock Zone can be subdivided into

a coastal phase and an interior phase. The coastal

phase is most typical of the zone, and it is west of Iron

Mountain and Agness. The interior phase is of minor

extent, and it is in the northeastern part of the survey

area, near Bobsgarden Mountain and in the Upper

Mule Creek drainageway.

The forest communities in the Western Hemlock

Zone consist of western hemlock and Douglas fir and

hardwoods such as bigleaf maple and cascara

buckthorn. Red alder is an aggressive invader in areas

that have been disturbed. Common understory

species include western swordfern, Oregon oxalis,

vine maple, Pacific rhododendron, salal, red

huckleberry, and cascade Oregongrape.

Dense stands of red alder regeneration occur

following disturbances such as fire or timber

harvesting. Tree plantings are subject to severe

competition from hardwood trees and from evergreen

and deciduous shrubs.

Tanoak/Hemlock Zone

The Tanoak/Hemlock Zone is south of the Western

Hemlock Zone and north of the Coastal Tanoak Zone.

In this zone, vegetation typical of the Western

Hemlock Zone is in transition with the mixed conifer

and evergreen vegetation described by Franklin and

Dyrness (Franklin and Dyrness 1973). In this

transitional area, tanoak forests from northern

California merge with western hemlock forests from

Oregon and Washington. The average annual

precipitation is about 90 to 130 inches. Elevation

ranges from 200 to 3,000 feet. The soils have a udic

moisture regime and a mesic temperature regime.

This zone correlates with general soil map units

8 and 9.

The forest communities in the Tanoak/Hemlock

Zone include tanoak, western hemlock, and Douglas

fir. From Edson Butte south to the Sixes River, the

prevalence of tanoak correlates with droughty soil

conditions and south aspects. Tanoak is prevalent

throughout the area south of the Sixes River.

Common understory species include western

swordfern, Oregon oxalis, vine maple, Pacific

rhododendron, salal, cascade Oregongrape, and

Pacific madrone.

The productivity of the forest in this zone is high.

Severe competition from a variety of evergreen and

deciduous shrubs is a concern. Red alder is

particularly aggressive after disturbances such as fire

or timber harvesting.

Cool Douglas Fir Zone

The Cool Douglas Fir Zone is at the higher

elevations on mountainslopes and summits. It extends

from the northeastern part of the survey area to the

southeastern part. The average annual precipitation is

about 90 to 160 inches, most of which falls as snow.

The soils in this zone generally are characterized by a

frigid temperature regime and a xeric moisture regime,

although some soils in the central part of the survey

area have a udic moisture regime. The udic area is

typified by Wildhorse Ridge to the north and Green

Craggies to the south. The xeric area is along the

eastern boundary of the survey area and extends

north to south. Elevation in this zone ranges from

2,500 to 4,500 feet in the northern part of the survey

area to 3,000 to 5,500 feet in the southern part. This

zone correlates with general soil map units 15, 19, and

20 and areas of unit 14 in the central part of the

survey area.

The Cool Douglas Fir Zone is characterized by

Douglas fir, tanoak, and white fir. Understory species

include cascade Oregongrape, Sadler oak, western

prince’s pine, golden chinkapin, western swordfern,

and Scouler bellflower.

The colder temperatures and short growing season

restrict the growth rate and regeneration of trees in

this zone. Areas that have been subject to

disturbances such as timber harvesting or fire develop

dense fields of brush.
320 Soil Survey of

Cool Western Hemlock Zone

The Cool Western Hemlock Zone is at the higher

elevations on mountainslopes and summits in the

northern part of the survey area. It includes Mt. Butler,

Iron Mountain, Panther Mountain, Saddle Peaks, and

Calvert Peak. The average annual precipitation is

about 130 to 160 inches, most of which falls as snow.

The soils have a frigid temperature regime and a udic

moisture regime. Elevation ranges from about 2,000 to

3,800 feet. Because this zone occurs as small,

isolated areas on mountain peaks and summits, many

areas could not be delineated on the general soil map

or the general vegetation map because of the

small scale used. This zone correlates with areas of

general soil map unit 14.

The Cool Western Hemlock Zone is characterized

by western hemlock and Douglas fir with minor

occurrences of western redcedar, sugar pine, and

incense cedar. Understory species include Pacific

rhododendron, cascade Oregongrape, red

huckleberry, salal, common beargrass, and western

prince’s pine.

The colder temperatures and short growing season

restrict the growth rate and regeneration of trees.

Areas that have been subject to disturbances such as

timber harvesting or fire develop dense fields of brush.

Cold White Fir Zone

The Cold White Fir Zone is at the highest elevations

in the survey area. It consists of small, isolated peaks

and narrow summits along the eastern boundary of

the survey area. The lowest elevations in this zone are

about 3,800 to 4,000 feet. The average annual

precipitation is about 100 to 160 inches, most of which

falls as snow. The growing season is very short, which

is in contrast to the rest of the survey area. The soils

have a xeric moisture regime and a frigid temperature

regime. Because this zone occurs as small, isolated

areas on mountain peaks and narrow summits, many

areas could not be delineated on the general soil map

or the general vegetation zone map because of the

small scale used. This zone correlates with areas of

general soil map unit 20.

Important tree species in this zone are Douglas fir

and white fir. Other less common species are Pacific

yew, incense cedar, western redcedar, Brewer spruce,

and western white pine. Understory shrubs include

western prince’s pine, Sadler oak, common

snowberry, sidebells shinleaf, cascade Oregongrape,

and big huckleberry. Pacific rhododendron occurs in

scattered areas.

The cold temperatures and short growing season

restrict the growth rate and regeneration of trees.

Areas that have been subject to disturbances such as

timber harvesting or fire develop dense fields of brush.

Climatic limitations, including cold temperatures, a

short growing season, and long periods of snowpack,

restrict management of this zone.

Shasta Red Fir Zone

The Shasta Red Fir Zone is north of Brandy Peak,

along the Bear Camp Ridge system. This zone is

unique to the survey area. The climate in this zone

is assumed to be colder than that in the adjacent

Cold White Fir Zone, and this zone has higher

effective precipitation, a shorter dry season in

summer, and a lower evapotranspiration rate. This

zone is concentrated on north-facing side slopes and

in level or concave areas on summits. It correlates with

the areas of general soil map unit 14 along the eastern

boundary of the survey area.

The Shasta Red Fir Zone supports vegetative

species similar to those of the Cold White Fir Zone,

except for the presence of Shasta red fir. Shasta red fir

may occur in nearly pure stands, but it more

commonly occurs in mixed stands with white fir and

Douglas fir.

The cold temperatures and short growing season

restrict the growth rate and regeneration of trees.

Areas that have been subject to disturbances such as

timber harvesting or fire develop dense brush fields of

Sadler oak and snowbrush ceanothus.

Windbreaks and Environmental Plantings

By Craig M. Ziegler, forester, Natural Resources Conservation

Service.

Wind can be a serious environmental and economic

concern. It can cause wind erosion, crop damage,

safety hazards, and energy loss. Windbreaks offer

landowners an effective conservation practice to

minimize the problems associated with uncontrolled

wind.

Field windbreaks protect crops and minimize wind

erosion. They are narrow plantings made at right

angles to the prevailing wind and at specific intervals

across a field. Research has shown significant

increases in yields of crops protected by properly

designed and maintained field windbreaks. Many

environmental changes occur on the leeward side of a

windbreak. Windspeed is reduced, transpiration by

plants is reduced, humidity is increased, evaporation is

reduced, and soil moisture is increased.

Farmstead windbreaks protect livestock, buildings,

and yards from wind. They also protect fruit trees and

gardens and provide habitat for wildlife. Several rows
Curry County, Oregon 321

of low- and high-growing shrubs and trees provide the

most protection.

Environmental plantings beautify areas, provide

shade, screen houses and other buildings, and help to

abate noise. The plants, mostly evergreen shrubs and

trees, should be closely spaced.

For a windbreak to be effective, the species of trees

or shrubs selected must be adapted to the soils.

Selecting the proper trees or shrubs is the first step

toward a successful windbreak. Permeability, available

water capacity, fertility, and depth are soil

characteristics that greatly affect the growth of trees

and shrubs.

Windspeed on the coast in the survey area can be

very high. Barren coastal sandy soils are subject to

erosion if they are exposed to windspeed of more

than 15 miles per hour. As the sand particles are

moved by the wind, they can greatly damage young

plants or even kill them by cutting them off at ground

level.

Proper site preparation prior to planting and control

of competing vegetation after planting are essential

when establishing a new windbreak. Replanting during

the first 3 to 5 years may be necessary to ensure that

the windbreak is fully stocked. Permanent irrigation

with drip systems or other methods may be needed in

areas where moisture is insufficient. Irrigation helps to

produce healthier, denser, and faster growing

windbreaks. Covering the soil with black polypropylene

woven fabric after the tree or shrub seedlings are

planted helps to control weeds and conserve moisture.

The fabric provides effective within-row weed control

for at least 5 years. It also provides a good mulch that

aids in conserving moisture and minimizing extremes

in soil temperature.

Each tree or shrub species has particular climatic

and physiographic limits. Within these limits, a tree or

shrub can be well suited or poorly suited for use as

windbreaks on a particular soil. Windbreak suitability

groups can be used as a guide for selecting the most

suitable species for different kinds of soils and for

predicting height and effectiveness of species. They

can be useful in selecting plants for windbreaks,

recreation and wildlife plantings, ornamental or

environmental plantings, reforestation, and criticalarea plantings.

Table 9 shows the height that locally grown trees

and shrubs are expected to reach in 20 years on

various soils. The estimates in the table are based on

measurements and observation of established

plantings that have been given adequate care. They

can be used as a guide in planning windbreaks and

screens. Additional information on planning

windbreaks and screens and planting and caring for

trees and shrubs can be obtained from the local office

of the Natural Resources Conservation Service or of

the Cooperative Extension Service or from a

commercial nursery.

Recreation

By Laura C. Burns, soil scientist, Natural Resources

Conservation Service.

Recreation is important to the economy of the

survey area. The natural resources, of which soils are

an important part, are used for many types of

recreational activities. Many public recreational

facilities and special events are provided to encourage

tourism. Besides camping areas, there are a number

of motels and resorts to accommodate visitors.

The Rogue, Illinois, Elk, and Chetco Rivers and the

North Fork of the Smith River are designated as “wild

and scenic” rivers. Many recreational activities are

centered on these rivers as well as the Winchuck and

Sixes Rivers. These activities include salmon and

steelhead fishing, swimming, whitewater rafting, hiking

along the rivers, and boating. Jet boating is very

popular on the Rogue River. Many of the creeks

commonly are used for trout fishing and for swimming.

The survey area has three wilderness areas that

total more than 195,000 acres. These areas are part of

the public land administered by the Bureau of Land

Management. The largest and best known is the

Kalmiopsis Wilderness, home of the rare Kalmiopsis

leachiana, a member of the Heath family. The other

wilderness areas are the Wild Rogue Wilderness and

the Grassy Knob Wilderness. A multitude of interesting

plants and animals can be observed and enjoyed in

these wilderness areas and in other parts of the

survey area. Many of these plants and animals are

abundant in the survey area but are rare in other

areas.

A variety of wildlife species can be observed,

photographed, and hunted in the survey area. Among

these are black-tailed deer; Roosevelt elk; black bear;

migratory waterfowl; upland game birds, including

quail, grouse, and wild turkey; band-tailed pigeon; bald

eagle; osprey; spotted owl; pine marten; ducks; doves;

bobcat; mountain lion; beaver; muskrat; coyote;

raccoon; river otter; California sea lion; Stellar sea lion;

harbor seal; marbled murrelet; amphibians; and

reptiles.

The survey areas provides many Federal, State,

county, and private parks and campgrounds that are

open to the public. It provides opportunities ranging

from backpacking in the wilderness areas to camping

at recreational vehicle parks with full hookups. There

are many trails in the Siskiyou National Forest,
322 Soil Survey of

including the Lower Rogue River, Rogue River,

Windy Valley, Illinois River, Shrader Old Growth,

Myrtle Tree, Redwood Nature, Vulcan Lake, and

Bombsite Trails, in addition to trails in the wilderness

areas. There are roads and other areas open to

off-road vehicle use.

The coastal areas of the survey are incredibly

beautiful and offer many recreational opportunities,

including observing the tide pools, hiking the Oregon

Coast Trail, camping, agate hunting, crabbing, surfing,

sailboarding at Floras Lake and Myers Creek Beach

south of Cape Sebastian, whale watching, surf fishing,

clam digging, and observing the ever-changing rocky

coastline and beaches. The main thoroughfare, U.S.

Highway 101, is very scenic and has numerous

viewpoints. Several parks are along the coast,

including Harris Beach, Samuel H. Boardman, Pistol

River, Cape Sebastian, Otter Point, Geisel Monument,

Humbug, Cape Blanco, and Floras Lake State Parks.

Three ports are available for commercial and

recreational boating in Brookings, Gold Beach, and

Port Orford. Deep-sea fishing and salmon fishing from

these ports are popular in summer.

The soils of the survey area are rated in table 10

according to limitations that affect their suitability for

recreation. The ratings are based on restrictive soil

features, such as wetness, slope, and texture of the

surface layer. Susceptibility to flooding is considered.

Not considered in the ratings, but important in

evaluating a site, are the location and accessibility of

the area, the size and shape of the area and its scenic

quality, vegetation, access to water, potential water

impoundment sites, and access to public sewer lines.

The capacity of the soil to absorb septic tank effluent

and the ability of the soil to support vegetation are also

important. Soils subject to flooding are limited for

recreational uses by the duration and intensity of

flooding and the season when flooding occurs. In

planning recreational facilities, onsite assessment of

the height, duration, intensity, and frequency of

flooding is essential.

In the table, the degree of soil limitation is

expressed as slight, moderate, or severe. Slight

means that soil properties are generally favorable and

that limitations are minor and easily overcome.

Moderate means that limitations can be overcome or

alleviated by planning, design, or special maintenance.

Severe means that soil properties are unfavorable and

that limitations can be offset only by costly soil

reclamation, special design, intensive maintenance,

limited use, or a combination of these measures.

The information in the table can be supplemented

by other information in this survey, for example,

interpretations for septic tank absorption fields in table

12 and interpretations for dwellings without basements

and for local roads and streets in table 11.

Camp areas require site preparation, such as

shaping and leveling the tent and parking areas,

stabilizing roads and intensively used areas, and

installing sanitary facilities and utility lines. Camp

areas are subject to heavy foot traffic and some

vehicular traffic. The best soils have mild slopes and

are not wet or subject to flooding during the period of

use. The surface has few or no stones or boulders,

absorbs rainfall readily but remains firm, and is not

dusty when dry. Strong slopes and stones or boulders

can greatly increase the cost of constructing

campsites.

Picnic areas are subject to heavy foot traffic. Most

vehicular traffic is confined to access roads and

parking areas. The best soils for picnic areas are firm

when wet, are not dusty when dry, are not subject to

flooding during the period of use, and do not have

slopes or stones or boulders that increase the cost of

shaping sites or of building access roads and parking

areas.

Playgrounds require soils that can withstand

intensive foot traffic. The best soils are almost level

and are not wet or subject to flooding during the

season of use. The surface is free of stones and

boulders, is firm after rains, and is not dusty when dry.

If grading is needed, the depth of the soil over bedrock

or a hardpan should be considered.

Paths and trails for hiking and horseback riding

should require little or no cutting and filling. The best

soils are not wet, are firm after rains, are not dusty

when dry, and are not subject to flooding more than

once a year during the period of use. They have

moderate slopes and few or no stones or boulders on

the surface.

Golf fairways are subject to heavy foot traffic and

some light vehicular traffic. Cutting or filling may be

required. The best soils for use as golf fairways are

firm when wet, are not dusty when dry, and are not

subject to prolonged flooding during the period of use.

They have moderate slopes and no stones or boulders

on the surface. The suitability of the soil for tees or

greens is not considered in rating the soils.

Wildlife Habitat

The kinds and numbers of wildlife species in the

survey area generally are related to the kinds of soils.

This relationship is indirect and is influenced by the

climatic zones, topography, land use, and plant

communities. Native plant communities consist of a

variety of vegetation, most of which is valuable as

habitat for wildlife. Wildlife habitat can be created or
Curry County, Oregon 323

improved by planting appropriate vegetation,

maintaining the existing plant cover, or promoting the

natural establishment of desirable plants.

Much of the survey area is mountainous and

heavily forested, but there are also cultivated areas

along the coastal margin. Such diverse environmental

conditions provide many types of wildlife habitat for an

abundance of wildlife species. The conditions in the

survey area range from those of the warm lower

elevations of the coastal plains and river valleys to

those of the cold higher elevations of the forested

mountains.

Water resources throughout the survey area

include ponds, lakes, reservoirs, rivers, and perennial

streams, all of which provide habitat for many species

of anadromous fish. The Pacific Ocean is adjacent to

the western margin of the survey area, and it is

extremely important in providing the habitat

requirements for salmonid fish populations as well as

for bottom-dwelling species. The Rogue River and its

tributaries are used extensively by anadromous fish

such as chinook salmon and steelhead trout. The

number of anadromous fish in this river and its

tributaries ranks second only to that in the Columbia

River. A major portion of the economy of the survey

area is dependent on the fishing industry, either as a

means of livelihood or as tourist activities such as

sportfishing.

Representative examples of fish using the water

resources in the survey area include several species

of salmonids, such as chinook salmon, coho salmon,

steelhead trout, rainbow trout, cutthroat trout,

American shad, striped bass, and sturgeon; several

species of bottom-dwelling fish, such as ling cod,

flounder, sea perch, and sea bass; and several

varieties of rockfish. Other vertebrates that use the

marine environment include seals; sea lions; whales;

otters; grebes; cormorants; mergansers; waterfowl

such as ducks, geese, and swans; shore birds such as

plovers, curlews, and sandpipers; sea ducks; gulls;

and terns. Marine invertebrates include worms such

as bloodworm, peanutworm, sandworm, and

tubeworm; mollusks such as clams, limpets, mussels,

oysters, scallops, and snails; and crustaceans such as

barnacles, copepods, crabs, and shrimp.

It is not practical to examine the life history

requirements of each of the 460 species of

vertebrates and the 178 freshwater and selected

marine fish species recognized to inhabit the land and

water of western Oregon and Washington; therefore,

Brown and others (USDA 1985) used the 16 major

groupings, or life forms, of terrestrial and aquatic

wildlife species as developed by Thomas and others

(USDA 1979) for the Blue Mountains province of

eastern Oregon and Washington. A life form is a group

of wildlife species whose requirements for habitat are

satisfied by similar successional stages within given

ecological communities. Using the life forms concept,

species can be grouped into communities or

associations based on vegetation used for reproducing

and feeding and as cover. Life Form 1 (species that

reproduce and feed in water) has been divided into

eight subgroups in order to describe more precisely

the breeding and feeding adaptations of fish and

invertebrates. A total of 24 different life forms,

therefore, was recognized by Brown and others for use

in managing wildlife and fish habitat in western Oregon

and Washington.

Several plant classification systems are used in

western Oregon and Washington. Of these, those

developed by Franklin and Dyrness (Franklin and

Dyrness 1973) and Kuchler (Kuchler 1964) have been

incorporated into the system developed by Thomas

and others. This system can then be used to correlate

plant communities to life forms. All of the life forms

were considered in the grouping of wildlife species into

habitat types and correlating them to the general soil

map units in this survey. Life Forms 1D, 1F, and 1H are

not discussed in the following paragraphs either

because they include only a minor number of species

or they are almost entirely associated with the

saltwater/marine environment. The life forms are as

follows:

Life Form 1.—Three species that reproduce in

water and feed in water. Representative species

include bullfrog and sea otter.

Life Form 1A.—Twenty-six species that reproduce

and feed in the water column. The eggs, larvae, and

juvenile forms are planktonic, and the adult form is

mobile. Representative species include striped bass,

copepods, and American shad.

Life Form 1B.—Seventeen species that reproduce

and feed in the water column. The adult form is

sedentary. Representative species include native

oysters and butter clams.

Life Form 1C.—Fifty species that reproduce in the

water column and feed in or on substrate. The adult

form is mobile. Representative species include starry

flounder, English sole, tubeworm, and Dungeness

crab.

Life Form 1D.—Seven species that reproduce in the

In this survey, the concept of life forms was used as

the basis for grouping wildlife species into habitat

types. The general soil map units shown on the

general soil map have been grouped into two

physiographic settings and one geologic separation

according to their potential to provide similar kinds of

wildlife habitat. These three groups and the kinds of

wildlife that inhabit each group are briefly described in

the following paragraphs.

Map units 1, 2, 3, 8, and 16.—These general soil

map units are on flood plains and stream terraces of

the Sixes, Elk, Rogue, Illinois, Pistol, Chetco, and

Winchuck Rivers and their tributaries and along

several of the larger creeks as well as on marine

terraces and established dunes adjacent to the Pacific

Ocean. General soil map units 1, 2, and 3 are along

the coastal margin of the survey area. They receive

70 to 90 inches of precipitation annually and have cool
Curry County, Oregon 325

to warm, moist summers with fog and cool to warm,

wet winters. General soil map units 8 and 16 are in the

interior of the survey area. They receive 80 to 100

inches of precipitation annually and have hot, moist to

dry summers and warm, wet winters.

The wildlife habitat in these map units is provided

by riparian vegetation, cultivated crops, and native

pasture. The vegetation in areas not cultivated

includes Sitka spruce, willow, rushes and sedges in

moist areas, and Douglas fir, grand fir, shore pine,

tanoak, California laurel, red alder, salal, evergreen

huckleberry, western swordfern, salmonberry,

coyotebrush, American dunegrass, and European

beachgrass in better drained areas. Redwood is in

general soil map unit 2. Cultivated areas are used for

grass-legume hay, irrigated and native pasture, and

specialty crops such as cranberries, lily bulbs, and

flowers for cutting.

Representative animals using the habitat types in

these map units are primarily those of life forms 1, 1A,

1B, 1C, 1E, 1G, 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14,

15, and 16. These map units are used at various times

of the year by many species of wildlife including sea

otter, clams, crabs, frogs and toads, mourning dove,

geese, ducks, deer, Roosevelt elk (fig. 12), coyote,

rabbits, beaver, muskrat, weasel, skunks, squirrels,

and many species of nongame birds such as hawks,

owls, crows, ravens, jays, woodpeckers, meadowlarks,

robins, herons, and numerous other songbirds that are

seasonally abundant. Steelhead trout, sturgeon, and

several species of salmon are in the rivers and

streams. Waterfowl are seasonally abundant in areas

near rivers or in areas of wetland.

Map units 4, 5, 6, 7, 9, 10, 12, 13, 14, 15, 17, 18,

and 20.—These general soil map units are on nearly

level to very steep hills and mountains along the

coastal margin of the survey area and throughout the

interior. Map units 4 and 6 are on broad summits and

side slopes of coastal hills and mountains, such as

Humbug Mountain, south of Port Orford; Vondergreen

Hill, east of Nesika Beach; and Cape Sebastian, south

of Gold Beach. These areas receive 75 to 95 inches of

precipitation annually and have cool, moist summers

with fog and cool, wet winters. Map unit 7 is in open

Figure 12.—Forested uplands and the associated bottom land provide excellent habitat for Roosevelt elk.
326 Soil Survey of

areas of grassland on broad to narrow summits and

side slopes of coastal hills and mountains, such as

Langlois Mountain, in the northern part of the survey

area, and near Carpenterville, between Hooskanaden

Creek and Whaleshead Creek. These areas receive

75 to 95 inches of precipitation annually and have

cool, moist summers with fog and cool, wet winters.

Map unit 5 is on broad summits and side slopes of

coastal hills and mountains, such as Peavine Ridge,

east of Brookings. These areas receive 90 to 130

inches of precipitation annually and have warm, moist

summers with fog and warm, wet winters.

The native overstory vegetation in map units 4, 5,

and 6 includes Douglas fir, grand fir, tanoak, Sitka

spruce, and Pacific madrone with minor amounts of

western hemlock. Map unit 5 also supports

redwood. The understory vegetation includes

salmonberry, salal, evergreen huckleberry, cascade

Oregongrape, western swordfern, California laurel,

and Pacific rhododendron with minor amounts of

common beargrass, baldhip rose, and vine maple.

The native vegetation in map unit 7 typically is

bentgrass, velvetgrass, crinkleawn fescue, sedges,

rushes, western brackenfern, red alder, and

western hazel with minor amounts of Pacific poison

oak.

Map units 9, 10, 12, and 13 are on broad summits

and side slopes of interior mountains, such as

Watches Butte, in the northern part of the survey area;

Fall Mountain, at the upper end of the Lobster Creek

drainageway; Skookumhouse Butte, immediately south

of the Rogue River, about 15 miles east of Gold

Beach; and the Gardner Ridge/Palmer Butte area,

east of Brookings. These areas receive 90 to 130

inches of precipitation annually and have hot, moist

summers and warm, wet winters. The native overstory

vegetation includes Douglas fir, tanoak, western

hemlock, Pacific madrone, and canyon live oak with

minor amounts of western redcedar, Port Orford

cedar, and Oregon white oak. The understory

vegetation includes cascade Oregongrape, salal,

evergreen huckleberry, western swordfern, Pacific

rhododendron, and common beargrass with minor

amounts of red huckleberry, creambush oceanspray,

western rattlesnake plantain, California laurel, western

prince’s pine, common snowberry, vine maple, Oregon

oxalis, trailing blackberry, white hawkweed, and

bearded fescue.

Map units 14 and 15 are on broad summits, slump

benches, and side slopes of interior mountains, such

as Edson Butte, southeast of Langlois; Sawtooth

Rock, east of Ophir; Bobs Garden Mountain, east of

Illahe; Game Lake Peak, south of Agness; Bosley

Butte, east of Carpenterville; and Quail Prairie

Mountain, near the Kalmiopsis Wilderness. These

areas receive 130 to 160 inches of precipitation

annually and have warm, moist summers and cool,

wet winters. The native overstory vegetation in these

higher elevation areas includes Douglas fir, tanoak,

and Pacific madrone with minor amounts of western

hemlock, white fir, Shasta red fir, golden chinkapin,

and Port Orford cedar. The understory vegetation

includes cascade Oregongrape, salal, red huckleberry,

western swordfern, Pacific rhododendron, common

beargrass, western rattlesnake plantain, western

prince’s pine, baldhip rose, and Sadler oak with minor

amounts of whitevein shinleaf, creeping snowberry,

western brackenfern, and coast fairybells.

Significant open areas of grassland are within the

forests in map units 10, 13, and 15. These include

areas such as Skookumhouse Prairie; First and

Second Prairie Mountains, in the Lobster Creek

drainageway; and Wildhorse Prairie, south of the

Rogue River, about 18 miles east of Gold Beach. The

native vegetation of these grassland areas includes

hedgehog dogtail, brome, California oatgrass,

bentgrass, bluegrass, western brackenfern, dock, and

woodrush. These open areas and areas on southfacing slopes provide range for deer and elk in winter;

however, use of these areas is limited by the low

production of forage and the poor-quality of the

browse.

Map units 17 and 18 are on broad summits, side

slopes, and canyon walls of interior mountains, such

as Raspberry Mountain, east of Agness; Devils

Backbone and Inspiration Point, in the Wild Rogue

Wilderness, near Paradise and Blossom Bars; and

Mule Mountain and Big Meadows, north of Marial.

These areas receive 80 to 100 inches of precipitation

annually and have hot, dry summers and warm, wet

winters. The native overstory vegetation includes

Douglas fir, tanoak, Pacific madrone, and canyon live

oak with minor amounts of ponderosa pine, California

black oak, sugar pine, and incense cedar. The

understory vegetation includes cascade Oregongrape,

common beargrass, western rattlesnake plantain,

baldhip rose, western brackenfern, deerfoot vanillaleaf,

Pacific poison oak, broadleaf starflower, California

honeysuckle, and whipplevine with minor amounts of

whitevein shinleaf, creeping snowberry, California

hazel, white hawkweed, trailing blackberry, bearded

fescue, and California fescue. The major difference

between map units 17 and 18 is the slightly higher

mean annual precipitation of map unit 18, which

corresponds with a subtle change in the understory

vegetation. In unit 18, salal, western swordfern, and

evergreen huckleberry are in the understory and are

dominant in some areas.
Curry County, Oregon 327

Map unit 20 is on broad summits and side slopes

of interior mountains, such as Bear Camp Mountain,

Burnt Ridge, Fish Hook Peak, and Brandy Peak,

east of Agness, and Mount Billingslea, on the

Curry-Josephine county line, in the center of the

Kalmiopsis Wilderness. These areas receive 90 to 120

inches of precipitation annually and have hot, dry

summers and cool, wet winters. The native overstory

vegetation in these high-elevation areas includes

Douglas fir and white fir with minor amounts of

western redcedar, Brewer’s spruce, western white

pine, and Shasta red fir. The understory vegetation

includes cascade Oregongrape, salal, common

beargrass, western swordfern, Sadler oak, western

rattlesnake plantain, baldhip rose, and deerfoot

vanillaleaf with minor amounts of greenleaf manzanita,

huckleberry oak, Pacific rhododendron, and western

prince’s pine.

Representative animals using the habitat types in

these map units are primarily those of life forms 2, 3,

4, 5, 6, 7, 10, 11, 12, 13, 14, and 15. The wildlife

species include salamanders; deer; Roosevelt elk;

bobcat; mountain lion; coyote; black bear; marten;

weasels; raccoon; several species of rodents; marbled

murrelet; porcupine; northern spotted owl; upland

game birds, such as wild turkey, ruffed grouse,

California quail, mountain quail, mourning dove, and

band-tailed pigeon; and numerous songbirds and

nongame birds, such as hawks, owls, eagles, turkey

vultures, crows, ravens, meadowlarks, woodpeckers,

and robins. Rivers, streams, and other bodies of water

in these areas provide habitat for river otter, beaver,

and many game fish, including several species of

salmon and steelhead trout.

As the abundance of shrubs increases in the

steeper areas of these map units, the abundance and

degree of use by wildlife species tends toward those

animals best adapted to use of shrubs. The diverse

structure of shrubs provides habitat niches that can be

used by a variety of species.

In the very steep areas of general soil map units 9,

10, 13, 14, 15, 17, 18, and 20, the vegetation is

dominantly tanoak, canyon live oak, Pacific madrone,

baldhip rose, several species of manzanita, common

beargrass, snowberry, whitevein shinleaf, and a variety

of fescues. These areas are more droughty and

generally are associated with cliffs or other rock

outcroppings, such as rimrock or talus. Wildlife

species adapted to the habitat in these areas include

chukar; several species of birds of prey, including

rough-legged hawk, golden eagle (winter only),

falcons, American kestrel, barn owl, screech owl,

great-horned owl, and turkey vulture; a variety of

rodents, such as pocket gopher, ground squirrel,

chipmunks, rabbits, and several species of mice;

numerous nongame birds, such as crows, ravens,

and wrens; and bats.

Map units 11 and 19.—These general soil map

units formed in ultramafic parent material such as

serpentine and peridotite. Most woodland areas in

these map units are considered to be impractical to

manage because of the low productivity and sparse

stands, which are caused by the inherent lack of

fertility and nutrient imbalance as a result of the parent

material. The soils in these map units are botanically

unique; they are the most floristically diverse units in

the survey area. Because of the plant diversity, there

is a wide range in the vertical structure and horizontal

patterns of habitat types that can be used by birds and

mammals. This diversity is greatest in areas where

these units interface with units that support more

typical forest plant communities. The open canopy

allows for considerable warming of the soil surface

during clear days in winter; thus, deer use the shrubs

for cover as they rest in these warm areas. Many open

areas and southerly aspects have patches of highly

palatable shrubs that can be used for browse by deer

and elk in winter. Areas of Rock outcrop generally are

associated with the steeper areas of these units.

Map unit 11 is on broad summits and side slopes of

interior mountains, such as Red Flat and Snow Camp

Mountains, east of Gold Beach, and Iron Mountain,

north of Agness. These areas receive 90 to 160 inches

of precipitation annually and have warm to hot, moist

summers and warm to cool, wet winters. The native

overstory vegetation includes Jeffrey pine, western

white pine, tanoak, knobcone pine, lodgepole pine,

and Port Orford cedar with minor amounts of Douglas

fir scattered throughout. The understory vegetation

includes California buckthorn, Sadler oak, huckleberry

oak, boxleaf silktassel, squawcarpet, pinemat

manzanita, greenleaf manzanita, and common

beargrass with minor amounts of incense cedar,

evergreen huckleberry, western swordfern, red

huckleberry, California laurel, whiteleaf manzanita,

and juniper.

Map unit 19 is on summits and side slopes of

interior mountains, such as the area immediately

south of the Rogue River, at Copper Canyon, about

2 to 3 miles west of Agness, and Chetco and Vulcan

Peaks, in the Kalmiopsis Wilderness. These areas

receive 80 to 120 inches of precipitation annually and

have hot, dry summers and warm to cool, wet winters.

The native overstory vegetation includes Jeffrey pine,

sugar pine, tanoak, incense cedar, knobcone pine,

lodgepole pine, and Port Orford cedar with minor

amounts of Douglas fir scattered throughout. The

understory vegetation includes California buckthorn,

huckleberry oak, boxleaf silktassel, squawcarpet,

pinemat manzanita, whiteleaf manzanita, common

beargrass, whiteleaf ceanothus, bearded fescue, red

fescue, and poison oak with minor amounts of western

swordfern, salal, red huckleberry, cascade

Oregongrape, California laurel, Lemmon needlegrass,

Sandberg bluegrass, and blue wildrye.

Representative animals that use the habitat in these

map units primarily are life forms 2, 3, 4, 5, 6, 7, 9, 10,

11, 12, 13, 14, and 15. The wildlife species include

salamanders; deer; Roosevelt elk; bobcat; mountain

lion; coyote; black bear; porcupine; weasels; raccoon;

several species of rodents; upland game birds, such

as wild turkey, ruffed grouse, California quail, mountain

quail, mourning dove, and band-tailed pigeon; and

numerous songbirds and nongame birds, such as

finches, cedar waxwing, goldfinches, wrens, hawks,

owls, eagles, turkey vulture, crows, ravens,

meadowlarks, woodpeckers, and robins. Rivers,

streams, and other bodies of water in these units

provide habitat for many game fish, including chinook

salmon and steelhead, rainbow, and cutthroat trout, as

well as for river otter and beaver.

As the abundance of shrubs increases in the

steeper areas of map units 11 and 19, the abundance

and degree of use by wildlife species tends toward

those animals best adapted to use of shrubs. The

diverse structure of shrubs provides habitat niches

that can be used by a variety of species.

In the very steep areas of these units, the

vegetation is dominantly Jeffrey pine, knobcone pine,

tanoak, incense cedar, several species of manzanita,

boxleaf silktassel, squawcarpet, California buckthorn,

whitevein shinleaf, and a variety of fescues,

needlegrasses, and bluegrasses. These areas are

more droughty and generally are associated with cliffs

or other rock outcroppings, such as rimrock or talus.

The wildlife species adapted to this habitat include

chukar; several species of birds of prey, including

rough-legged hawk, golden eagle (winter only),

falcons, American kestrel, barn owl, screech owl,

great-horned owl, and turkey vulture; a variety of

rodents, such as pocket gopher, ground squirrel,

chipmunks, rabbits, and several species of mice;

numerous nongame birds, such as crows, ravens, and

wrens; and bats.

Engineering

This section provides information for planning land

uses related to urban development and to water

management. Soils are rated for various uses, and the

most limiting features are identified. Ratings are given

for building site development, sanitary facilities,

construction materials, and water management. The

ratings are based on observed performance of the

soils and on the estimated data and test data in the

“Soil Properties” section.

Information in this section is intended for land use

planning, for evaluating land use alternatives, and for

planning site investigations prior to design and

construction. The information, however, has limitations.

For example, estimates and other data generally apply

only to that part of the soil within a depth of 5 or 6 feet.

Because of the map scale, small areas of different

soils may be included within the mapped areas of a

specific soil.

The information is not site specific and does not

eliminate the need for onsite investigation of the soils

or for testing and analysis by personnel experienced in

the design and construction of engineering works.

Government ordinances and regulations that

restrict certain land uses or impose specific design

criteria were not considered in preparing the

information in this section. Local ordinances and

regulations should be considered in planning, in site

selection, and in design.

Soil properties, site features, and observed

performance were considered in determining the

ratings in this section. During the fieldwork for this soil

survey, determinations were made about grain-size

distribution, liquid limit, plasticity index, soil reaction,

depth to bedrock, hardness of bedrock within 5 or 6

feet of the surface, soil wetness, depth to a seasonal

high water table, slope, likelihood of flooding, natural

soil structure aggregation, and soil density. Data were

collected about kinds of clay minerals, mineralogy of

the sand and silt fractions, and the kinds of adsorbed

cations. Estimates were made for erodibility,

permeability, corrosivity, shrink-swell potential,

available water capacity, and other behavioral

characteristics affecting engineering uses.

This information can be used to evaluate the

potential of areas for residential, commercial,

industrial, and recreational uses; make preliminary

estimates of construction conditions; evaluate

alternative routes for roads, streets, highways,

pipelines, and underground cables; evaluate

alternative sites for sanitary landfills, septic tank

absorption fields, and sewage lagoons; plan detailed

onsite investigations of soils and geology; locate

potential sources of gravel, sand, earthfill, and topsoil;

plan drainage systems, irrigation systems, ponds,

terraces, and other structures for soil and water

conservation; and predict performance of proposed

small structures and pavements by comparing the

performance of existing similar structures on the same

or similar soils.
Curry County, Oregon 329

The information in the tables, along with the soil

maps, the soil descriptions, and other data provided in

this survey, can be used to make additional

interpretations.

Some of the terms used in this soil survey have a

special meaning in soil science and are defined in the

Glossary.

Building Site Development

Table 11 shows the degree and kind of soil

limitations that affect shallow excavations, dwellings

with and without basements, small commercial

buildings, local roads and streets, and lawns and

landscaping. The limitations are considered slight if

soil properties and site features are generally

favorable for the indicated use and limitations are

minor and easily overcome; moderate if soil properties

or site features are not favorable for the indicated use

and special planning, design, or maintenance is

needed to overcome or minimize the limitations; and

severe if soil properties or site features are so

unfavorable or so difficult to overcome that special

design, significant increases in construction costs, and

possibly increased maintenance are required. Special

feasibility studies may be required where the soil

limitations are severe.

Shallow excavations are trenches or holes dug to a

maximum depth of 5 or 6 feet for basements, graves,

utility lines, open ditches, and other purposes. The

ratings are based on soil properties, site features,

and observed performance of the soils. The ease of

digging, filling, and compacting is affected by the

depth to bedrock, a cemented pan, or a very firm

dense layer; stone content; soil texture; and slope.

The time of the year that excavations can be made is

affected by the depth to a seasonal high water table

and the susceptibility of the soil to flooding. The

resistance of the excavation walls or banks to

sloughing or caving is affected by soil texture and

depth to the water table.

Dwellings and small commercial buildings are

structures built on shallow foundations on undisturbed

soil. The load limit is the same as that for single-family

dwellings no higher than three stories. Ratings are

made for small commercial buildings without

basements, for dwellings with basements, and for

dwellings without basements. The ratings are based

on soil properties, site features, and observed

performance of the soils. A high water table, flooding,

shrinking and swelling, and organic layers can cause

the movement of footings. A high water table, depth to

bedrock or to a cemented pan, large stones, slope,

and flooding affect the ease of excavation and

construction. Landscaping and grading that require

cuts and fills of more than 5 or 6 feet are not

considered.

Local roads and streets have an all-weather surface

and carry automobile and light truck traffic all year.

They have a subgrade of cut or fill soil material; a base

of gravel, crushed rock, or stabilized soil material; and

a flexible or rigid surface. Cuts and fills are generally

limited to less than 6 feet. The ratings are based on

soil properties, site features, and observed

performance of the soils. Depth to bedrock or to a

cemented pan, a high water table, flooding, large

stones, and slope affect the ease of excavating and

grading. Soil strength (as inferred from the engineering

classification of the soil), shrink-swell potential, frost

action potential, and depth to a high water table affect

the traffic-supporting capacity.

Lawns and landscaping require soils on which turf

and ornamental trees and shrubs can be established

and maintained. The ratings are based on soil

properties, site features, and observed performance of

the soils. Soil reaction, a high water table, depth to

bedrock or to a cemented pan, the available water

capacity in the upper 40 inches, and the content of

salts, sodium, and sulfidic materials affect plant

growth. Flooding, wetness, slope, stoniness, and

the amount of sand, clay, or organic matter in the

surface layer affect trafficability after vegetation is

established.

Sanitary Facilities

Table 12 shows the degree and kind of soil

limitations that affect septic tank absorption fields,

sewage lagoons, and sanitary landfills. The limitations

are considered slight if soil properties and site features

are generally favorable for the indicated use and

limitations are minor and easily overcome; moderate if

soil properties or site features are not favorable for the

indicated use and special planning, design, or

maintenance is needed to overcome or minimize the

limitations; and severe if soil properties or site features

are so unfavorable or so difficult to overcome that

special design, significant increases in construction

costs, and possibly increased maintenance are

required.

The table also shows the suitability of the soils for

use as daily cover for landfill. A rating of good

indicates that soil properties and site features are

favorable for the use and good performance and low

maintenance can be expected; fair indicates that soil

properties and site features are moderately favorable

for the use and one or more soil properties or site

features make the soil less desirable than the soils

rated good; and poor indicates that one or more soil

properties or site features are unfavorable for the use
330 Soil Survey of

and overcoming the unfavorable properties requires

special design, extra maintenance, or costly alteration.

Septic tank absorption fields are areas in which

effluent from a septic tank is distributed into the soil

through subsurface tiles or perforated pipe. Only that

part of the soil between depths of 24 and 72 inches is

evaluated. The ratings are based on soil properties,

site features, and observed performance of the soils.

Permeability, a high water table, depth to bedrock or to

a cemented pan, and flooding affect absorption of the

effluent. Large stones and bedrock or a cemented pan

interfere with installation.

Unsatisfactory performance of septic tank

absorption fields, including excessively slow

absorption of effluent, surfacing of effluent, and

hillside seepage, can affect public health. Ground

water can be polluted if highly permeable sand and

gravel or fractured bedrock is less than 4 feet below

the base of the absorption field, if slope is excessive,

or if the water table is near the surface. There must

be unsaturated soil material beneath the absorption

field to filter the effluent effectively. Many local

ordinances require that this material be of a certain

thickness.

Sewage lagoons are shallow ponds constructed to

hold sewage while aerobic bacteria decompose the

solid and liquid wastes. Lagoons should have a nearly

level floor surrounded by cut slopes or embankments

of compacted soil. Lagoons generally are designed to

hold the sewage within a depth of 2 to 5 feet. Nearly

impervious soil material for the lagoon floor and sides

is required to minimize seepage and contamination of

ground water.

The table gives ratings for the natural soil that

makes up the lagoon floor. The surface layer and,

generally, 1 or 2 feet of soil material below the surface

layer are excavated to provide material for the

embankments. The ratings are based on soil

properties, site features, and observed performance of

the soils. Considered in the ratings are slope,

permeability, a high water table, depth to bedrock or to

a cemented pan, flooding, large stones, and content of

organic matter.

Excessive seepage resulting from rapid

permeability in the soil or a water table that is high

enough to raise the level of sewage in the lagoon

causes a lagoon to function unsatisfactorily. Pollution

results if seepage is excessive or if floodwater

overtops the lagoon. A high content of organic matter

is detrimental to proper functioning of the lagoon

because it inhibits aerobic activity. Slope, bedrock, and

cemented pans can cause construction problems, and

large stones can hinder compaction of the lagoon

floor.

Sanitary landfills are areas where solid waste is

disposed of by burying it in soil. There are two types of

landfill—trench and area. In a trench landfill, the waste

is placed in a trench. It is spread, compacted, and

covered daily with a thin layer of soil excavated at the

site. In an area landfill, the waste is placed in

successive layers on the surface of the soil. The waste

is spread, compacted, and covered daily with a thin

layer of soil from a source away from the site.

Both types of landfill must be able to bear heavy

vehicular traffic. Both types involve a risk of groundwater pollution. Ease of excavation and revegetation

should be considered.

The ratings in the table are based on soil

properties, site features, and observed performance of

the soils. Permeability, depth to bedrock or to a

cemented pan, a high water table, slope, and flooding

affect both types of landfill. Texture, stones and

boulders, highly organic layers, soil reaction, and

content of salts and sodium affect trench landfills.

Unless otherwise stated, the ratings apply only to that

part of the soil within a depth of about 6 feet. For

deeper trenches, a limitation rated slight or moderate

may not be valid. Onsite investigation is needed.

Daily cover for landfill is the soil material that is

used to cover compacted solid waste in an area

sanitary landfill. The soil material is obtained offsite,

transported to the landfill, and spread over the waste.

Soil texture, wetness, coarse fragments, and slope

affect the ease of removing and spreading the material

during wet and dry periods. Loamy or silty soils that

are free of large stones or excess gravel are the best

cover for a landfill. Clayey soils are sticky or cloddy

and are difficult to spread; sandy soils are subject to

wind erosion.

After soil material has been removed, the soil

material remaining in the borrow area must be thick

enough over bedrock, a cemented pan, or the water

table to permit revegetation. The soil material used as

the final cover for a landfill should be suitable for

plants. The surface layer generally has the best

workability, more organic matter, and the best potential

for plants. Material from the surface layer should be

stockpiled for use as the final cover.

Construction Materials

Table 13 gives information about the soils as a

source of roadfill, sand, gravel, and topsoil. The soils

are rated good, fair, or poor as a source of roadfill and

topsoil. They are rated as a probable or improbable

source of sand and gravel. The ratings are based on

soil properties and site features that affect the removal

of the soil and its use as construction material. Normal

compaction, minor processing, and other standard
Curry County, Oregon 331

construction practices are assumed. Each soil is

evaluated to a depth of 5 or 6 feet.

Roadfill is soil material that is excavated in one

place and used in road embankments in another

place. In this table, the soils are rated as a source of

roadfill for low embankments, generally less than 6

feet high and less exacting in design than higher

embankments.

The ratings are for the soil material below the

surface layer to a depth of 5 or 6 feet. It is assumed

that soil layers will be mixed during excavating and

spreading. Many soils have layers of contrasting

suitability within their profile. The table showing

engineering index properties provides detailed

information about each soil layer. This information can

help to determine the suitability of each layer for use

as roadfill. The performance of soil after it is stabilized

with lime or cement is not considered in the ratings.

The ratings are based on soil properties, site

features, and observed performance of the soils. The

thickness of suitable material is a major consideration.

The ease of excavation is affected by large stones, a

high water table, and slope. How well the soil performs

in place after it has been compacted and drained is

determined by its strength (as inferred from the

engineering classification of the soil) and shrink-swell

potential.

Soils rated good contain significant amounts of

sand or gravel or both. They have at least 5 feet of

suitable material, a low shrink-swell potential, few

cobbles and stones, and slopes of 15 percent or less.

Depth to the water table is more than 3 feet. Soils

rated fair are more than 35 percent silt- and clay-sized

particles and have a plasticity index of less than 10.

They have a moderate shrink-swell potential, slopes of

15 to 25 percent, or many stones. Depth to the water

table is 1 to 3 feet. Soils rated poor have a plasticity

index of more than 10, a high shrink-swell potential,

many stones, or slopes of more than 25 percent. They

are wet and have a water table at a depth of less than

1 foot. They may have layers of suitable material, but

the material is less than 3 feet thick.

Sand and gravel are natural aggregates suitable for

commercial use with a minimum of processing. They

are used in many kinds of construction. Specifications

for each use vary widely. In the table, only the

probability of finding material in suitable quantity is

evaluated. The suitability of the material for specific

purposes is not evaluated, nor are factors that affect

excavation of the material.

The properties used to evaluate the soil as a source

of sand or gravel are gradation of grain sizes (as

indicated by the engineering classification of the soil),

the thickness of suitable material, and the content of

rock fragments. Kinds of rock, acidity, and stratification

are given in the soil series descriptions. Gradation of

grain sizes is given in the table on engineering index

properties.

A soil rated as a probable source has a layer of

clean sand or gravel or a layer of sand or gravel that is

up to 12 percent silty fines. This material must be at

least 3 feet thick and less than 50 percent, by weight,

large stones. All other soils are rated as an improbable

source. Coarse fragments of soft bedrock, such as

shale and siltstone, are not considered to be sand and

gravel.

Topsoil is used to cover an area so that vegetation

can be established and maintained. The upper 40

inches of a soil is evaluated for use as topsoil. Also

evaluated is the reclamation potential of the borrow

area.

Plant growth is affected by toxic material and by

such properties as soil reaction, available water

capacity, and fertility. The ease of excavating, loading,

and spreading is affected by rock fragments, slope, a

water table, soil texture, and thickness of suitable

material. Reclamation of the borrow area is affected by

slope, a water table, rock fragments, bedrock, and

toxic material.

Soils rated good have friable, loamy material to a

depth of at least 40 inches. They are free of stones

and cobbles, have little or no gravel, and have slopes

of less than 8 percent. They are low in content of

soluble salts, are naturally fertile or respond well to

fertilizer, and are not so wet that excavation is difficult.

Soils rated fair are sandy soils, loamy soils that

have a relatively high content of clay, soils that have

only 20 to 40 inches of suitable material, soils that

have an appreciable amount of gravel, stones, or

soluble salts, or soils that have slopes of 8 to 15

percent. The soils are not so wet that excavation is

difficult.

Soils rated poor are very sandy or clayey, have less

than 20 inches of suitable material, have a large

amount of gravel, stones, or soluble salts, have slopes

of more than 15 percent, or have a seasonal high

water table at or near the surface.

The surface layer of most soils is generally

preferred for topsoil because of its organic matter

content. Organic matter greatly increases the

absorption and retention of moisture and nutrients for

plant growth.

Water Management

Table 14 gives information on the soil properties

and site features that affect water management. The

degree and kind of soil limitations are given for pond

reservoir areas and embankments, dikes, and levees.
332 Soil Survey of

The limitations are considered slight if soil properties

and site features are generally favorable for the

indicated use and limitations are minor and are easily

overcome; moderate if soil properties or site features

are not favorable for the indicated use and special

planning, design, or maintenance is needed to

overcome or minimize the limitations; and severe if soil

properties or site features are so unfavorable or so

difficult to overcome that special design, significant

increase in construction costs, and possibly increased

maintenance are required.

This table also gives for each soil the restrictive

features that affect drainage, irrigation, terraces and

diversions, and grassed waterways.

Pond reservoir areas hold water behind a dam or

embankment. Soils best suited to this use have low

seepage potential in the upper 60 inches. The

seepage potential is determined by the permeability of

the soil and the depth to fractured bedrock or other

permeable material. Excessive slope can affect the

storage capacity of the reservoir area.

Embankments, dikes, and levees are raised

structures of soil material, generally less than 20 feet

high, constructed to impound water or to protect land

against overflow. In this table, the soils are rated as a

source of material for embankment fill. The ratings

apply to the soil material below the surface layer to a

depth of about 5 feet. It is assumed that soil layers will

be uniformly mixed and compacted during

construction.

The ratings do not indicate the ability of the natural

soil to support an embankment. Soil properties to a

depth even greater than the height of the embankment

can affect performance and safety of the embankment.

Generally, deeper onsite investigation is needed to

determine these properties.

Soil material in embankments must be resistant to

seepage, piping, and erosion and have favorable

compaction characteristics. Unfavorable features

include less than 5 feet of suitable material and a high

content of stones or boulders, organic matter, or salts

or sodium. A high water table affects the amount of

usable material. It also affects trafficability.

Drainage is the removal of excess surface and

subsurface water from the soil. How easily and

effectively the soil is drained depends on the depth to

bedrock, to a cemented pan, or to other layers that

affect the rate of water movement; permeability; depth

to a high water table or depth of standing water if the

soil is subject to ponding; slope; susceptibility to

flooding; subsidence of organic layers; and the

potential for frost action. Excavating and grading and

the stability of ditchbanks are affected by depth to

bedrock or to a cemented pan, large stones, slope,

and the hazard of cutbanks caving. The productivity of

the soil after drainage is adversely affected by extreme

acidity or by toxic substances in the root zone, such as

salts, sodium, and sulfur. Availability of drainage

outlets is not considered in the ratings.

Irrigation is the controlled application of water to

supplement rainfall and support plant growth. The

design and management of an irrigation system are

affected by depth to the water table, the need for

drainage, flooding, available water capacity, intake

rate, permeability, erosion hazard, and slope. The

construction of a system is affected by large stones

and depth to bedrock or to a cemented pan. The

performance of a system is affected by the depth of

the root zone, the amount of salts or sodium, and soil

reaction.

Terraces and diversions are embankments or a

combination of channels and ridges constructed

across a slope to control erosion and conserve

moisture by intercepting runoff. Slope, wetness, large

stones, and depth to bedrock or to a cemented pan

affect the construction of terraces and diversions. A

restricted rooting depth, a severe hazard of wind

erosion or water erosion, an excessively coarse

texture, and restricted permeability adversely affect

maintenance.

Grassed waterways are natural or constructed

channels, generally broad and shallow, that conduct

surface water to outlets at a nonerosive velocity.

Large stones, wetness, slope, and depth to

bedrock or to a cemented pan affect the

construction of grassed waterways. A hazard of

wind erosion, low available water capacity, restricted

rooting depth, toxic substances such as salts and

sodium, and restricted permeability adversely affect

the growth and maintenance of the grass after

construction.

Slope Stability

By Paul F. Pedone, geologist, and Gerald J. Weinheimer, Jr.,

soil scientist, Natural Resources Conservation Service; and Cindy

Ricks, resource geologist, Siskiyou National Forest.

This section provides information on the stability of

the soils in the survey area, which is a major concern

in planning land uses.

The mountains of the survey area generally are

characterized by steep slopes, relief of as much as

5,000 feet, and moderate dissection by streams and

rivers. Steep slopes, incompetent geologic units, and

unstable soil units result in numerous and varied slope

failures. Mass movement of soil material and rock is a

normal geologic process; however, roadbuilding and

timber harvesting can accelerate the rate of
Curry County, Oregon 333

movement. The negative impact from these activities

can be minimized if the factors affecting slope stability

are carefully considered.

The four major factors affecting slope stability in the

survey area are discussed in this section. The factors

include ground water, the angle of the slope, the

characteristics of the soils, and the characteristics of

the bedrock.

Ground water.—Saturation by ground water is a

major cause of slope failure. In areas of all types of

rock and soil and on a wide range of slope angles, the

potential for slope failure is significantly increased if

the material is saturated.

Slope angle.—The general relationship between the

angle and stability of the slopes in the survey area is

shown below. The slope limits can vary somewhat

depending on the type and structure of the rock, the

characteristics and aspect of the soil, and the

influence of the ground water.

0 to 40 percent ............ stable when dry or saturated

except in areas of very poorly drained soils

where earthflows can develop

40 to 55 percent ......... stable when dry; marginally

stable when saturated

55 to 75 percent ......... stable to marginally stable

when dry; unstable when saturated

More than 75 percent ....... subject to ravel when dry;

 very unstable when saturated

Soil characteristics.—Different soil types have

varying stability characteristics. Generally, coarse

textured and less cohesive soils (sand and gravel) are

more likely to ravel or form dry flows on steep, dry

slopes. On wet slopes, finer textured or poorly drained

soils (silt and clay) are more cohesive and tend to

slide at lower slope angles than do coarse textured,

well drained soils.

Bedrock characteristics.—Different types of rock

have varying characteristics. Soil characteristics are

partially defined by local bedrock. Clayey soils are

derived from shale, mudstone, schist, and other rock

that is composed of minerals that weather to clay.

Sandy soils are derived from sandstone,

conglomerate, diorite, and gabbro that generally are

more resistant to weathering. Rocks that have weak

internal structure, such as sheared serpentinite, can

be very unstable on steep slopes, especially if it is

saturated. Bedrock features such as bedding planes,

fractures and faults, or fold structures can affect slope

stability by weakening the rock, increasing the depth of

weathering, and influencing the movement of ground

water. Where the layers of rock are parallel to the

slope, such as in areas of the Colebrooke Schist

Formation, cut slopes are subject to slumping or

sliding at the soil/bedrock contact. In fault shear

zones, increased slide activity and large landslide

complexes may occur on moderate to steep slopes.

Shear zones vary in width from tens to hundreds of

feet. Soils that formed in the shear zones tend to be

very deep to bedrock and wet because of the

influence of the ground-water flow (Ferrero 1991). The

largest areas that exhibit the influence of shear zones

on slope stability are the Hooskanaden Slide, between

the community of Carpenterville and U.S. Highway

101, and the area south of Humbug Mountain.

Rotational slides, earthflows, and translational

slides are the most common types of landslides in

the survey area. Debris avalanches and rock slides

also occur, but they are significantly less common

(Henkle and others 1991).

Although rotational slides (fig. 13) occur in areas of

soils derived from all types of parent material, they

most commonly occur in areas of clayey soils that

formed in mudstone and shale of the Dothan and Otter

Point Formations. These soils have a high percentage

of silt and clay, tend to be poorly drained, and can

form a hummocky slump complex on moderate to

steep slopes, especially if they are saturated by

springs and runoff. Notable examples are the

Etelka and Whobrey soils in the Eckley area, in the

northern part of the survey area. Areas underlain by

Tertiary shale are prone to rotational sliding because

they are less indurated and therefore more

susceptible to deep weathering. In areas where

mudstone and sandstone are interbedded, the

ridgetops, shoulders, knobs, and other convex areas

generally are in the areas of sandstone and the

backslopes, more gently sloping areas, footslopes,

toeslopes, and other concave areas generally are in

the areas of mudstone.

Earthflows (fig. 14) are common in areas of

waterladen soil, rock, and organic material in steep

stream channels (Busby and Bestland 1992).

Earthflows can occur in areas of soils derived from

any type of parent material, especially where manmade disturbances have occurred, but they are most

common in areas of soils derived from serpentinitic

rock. Saturation of serpentinitic soils from springs or

runoff results in earthflow complexes. All serpentinitic

soils are potentially active because sheared

serpentinite has little internal strength; however, most

of the slides and earthflows occur at or near the

thrust-fault contact of serpentinitic rock with other

underlying formations. The thrust plate acts as a

watercourse, which increases the pore pressure within

the rock mass and further weakens the strength of the

rock (Henkle and others 1991). Because of the volume
334 Soil Survey of

of material moved by earthflows, stream channels

commonly are blocked by slide debris (Ferrero 1991).

Translational slides (fig. 15) generally are surficial

soil movements that occur on steep slopes, commonly

slopes of 65 percent or more. These slides occur as

shallow sliding or raveling of soil and rock material at

the soil/bedrock contact. A low content of clay and a

high content of rock fragments increase the

susceptibility of soils to translational slides, which

occur most often along inner gorges (fig. 16) in areas

immediately adjacent to streams and above the

channel in the area below the first break in the slope

(Busby and Bestland 1992). Inner gorge slides are

common in areas of all types of parent material, but

areas underlain by serpentinitic rock are especially

active.

Debris avalanches (fig. 17) are slope failures that

involve rapid movement of large volumes of material.

These failures generally are triggered by debris slides

on adjacent hillslopes or by the movement of debris in

a channel as a result of water saturation (Busby and

Bestland 1992). Debris avalanches are fairly rare and

occur mainly in areas of serpentinitic rock.

Rock slides are common near outcroppings of

gabbro and diorite, well-cemented areas of the Dothan

Formation, Tertiary conglomerate, and the Humbug

Formation (Ferrero 1991).

An attempt to measure the frequency of all types of

landslides on differing types of parent material was

made by Henkle and others (Henkle and others 1991).

Their findings indicate that soils underlain by

serpentinitic rock have a landslide density nearly twice

that of soils underlain by the Dothan Formation. In

areas of the Colebrooke Schist Formation, the

landslide density is about 1.3 times that of areas

underlain by the Dothan Formation. The landslide

density of gabbro is about 1.2 times that of areas

underlain by the Dothan Formation.

Data relating to soil properties are collected during

the course of the soil survey. The data and the

estimates of soil and water features, listed in tables,

are explained on the following pages.

Soil properties are determined by field examination

of the soils and by laboratory index testing of some

benchmark soils. Established standard procedures are

followed. During the survey, many shallow borings are

made and examined to identify and classify the soils

and to delineate them on the soil maps. Samples are

taken from some typical profiles and tested in the

laboratory to determine grain-size distribution,

plasticity, and compaction characteristics.

Estimates of soil properties are based on field

examinations, on laboratory tests of samples from the

survey area, and on laboratory tests of samples of

similar soils in nearby areas. Tests verify field

observations, verify properties that cannot be

estimated accurately by field observation, and help to

characterize key soils.

The estimates of soil properties shown in the tables

include the range of grain-size distribution and

Atterberg limits, the engineering classification, and the

physical and chemical properties of the major layers of

each soil. Pertinent soil and water features also are

given.

Engineering Index Properties

Table 15 gives estimates of the engineering

classification and of the range of index properties for

the major layers of each soil in the survey area. Most

soils have layers of contrasting properties within the

upper 5 or 6 feet.

Depth to the upper and lower boundaries of each

layer is indicated. The range in depth and information

on other properties of each layer are given for each

soil series under the heading “Soil Series and Their

Morphology.”

Texture is given in the standard terms used by the

U.S. Department of Agriculture. These terms are

defined according to percentages of sand, silt, and

clay in the fraction of the soil that is less than 2

millimeters in diameter. “Loam,” for example, is soil that

is 7 to 27 percent clay, 28 to 50 percent silt, and less

than 52 percent sand. If the content of particles

coarser than sand is as much as about 15 percent, an

appropriate modifier is added, for example, “gravelly.”

Textural terms are defined in the Glossary.

Classification of the soils is determined according to

the Unified soil classification system (ASTM 1993,

Portland Cement Association 1973) and the system

adopted by the American Association of State

Highway and Transportation Officials (AASHTO 1986,

Portland Cement Association 1973).

The Unified system classifies soils according to

properties that affect their use as construction

material. Soils are classified according to grain-size

distribution of the fraction less than 3 inches in

diameter and according to plasticity index, liquid limit,

and organic matter content. Sandy and gravelly soils

are identified as GW, GP, GM, GC, SW, SP, SM, and

SC; silty and clayey soils as ML, CL, OL, MH, CH, and

OH; and highly organic soils as PT. Soils exhibiting

engineering properties of two groups can have a dual

classification, for example, CL-ML.

The AASHTO system classifies soils according to

those properties that affect roadway construction and

maintenance. In this system, the fraction of a mineral

soil that is less than 3 inches in diameter is classified

in one of seven groups from A-1 through A-7 on the

basis of grain-size distribution, liquid limit, and

plasticity index. Soils in group A-1 are coarse grained

and low in content of fines (silt and clay). At the other

extreme, soils in group A-7 are fine grained. Highly

organic soils are classified in group A-8 on the basis of

visual inspection.

Rock fragments larger than 10 inches in diameter

and 3 to 10 inches in diameter are indicated as a

percentage of the total soil on a dry-weight basis. The

percentages are estimates determined mainly by

converting volume percentage in the field to weight

percentage.

Percentage (of soil particles) passing designated

sieves is the percentage of the soil fraction less than

3 inches in diameter based on an ovendry weight. The

sieves, numbers 4, 10, 40, and 200 (USA Standard

Series), have openings of 4.76, 2.00, 0.420, and 0.074

millimeters, respectively. Estimates are based on

laboratory tests of soils sampled in the survey area

Soil Properties
338 Soil Survey of

and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits)

indicate the plasticity characteristics of a soil. The

estimates are based on test data from the survey area

or from nearby areas and on field examination.

The estimates of grain-size distribution, liquid limit,

and plasticity index are generally rounded to the

nearest 5 percent. Thus, if the ranges of gradation and

Atterberg limits extend a marginal amount (1 or 2

percentage points) across classification boundaries,

the classification in the marginal zone is omitted in the

table.

Physical and Chemical Properties

Table 16 shows estimates of some characteristics

and features that affect soil behavior. These estimates

are given for the major layers of each soil in the survey

area. The estimates are based on field observations

and on test data for these and similar soils.

Clay as a soil separate consists of mineral soil

particles that are less than 0.002 millimeter in

diameter. In this table, the estimated clay content of

each major soil layer is given as a percentage, by

weight, of the soil material that is less than 2

millimeters in diameter.

The amount and kind of clay greatly affect the

fertility and physical condition of the soil. They

determine the ability of the soil to adsorb cations and

to retain moisture. They influence shrink-swell

potential, permeability, plasticity, the ease of soil

dispersion, and other soil properties. The amount and

kind of clay in a soil also affect tillage and earthmoving

operations.

Moist bulk density is the weight of soil (ovendry) per

unit volume. Volume is measured when the soil is at

field moisture capacity, that is, the moisture content at

1

/3-bar moisture tension. Weight is determined after

drying the soil at 105 degrees C. In this table, the

estimated moist bulk density of each major soil

horizon is expressed in grams per cubic centimeter of

soil material that is less than 2 millimeters in diameter.

Bulk density data are used to compute shrink-swell

potential, available water capacity, total pore space,

and other soil properties. The moist bulk density of a

soil indicates the pore space available for water and

roots. A bulk density of more than 1.6 can restrict

water storage and root penetration. Moist bulk density

is influenced by texture, kind of clay, content of organic

matter, and soil structure.

Permeability refers to the ability of a soil to transmit

water or air. The estimates indicate the rate of

downward movement of water when the soil is

saturated. They are based on soil characteristics

observed in the field, particularly structure, porosity,

and texture. Permeability is considered in the design of

soil drainage systems and septic tank absorption

fields.

Available water capacity refers to the quantity of

water that the soil is capable of storing for use by

plants. The capacity for water storage is given in

inches of water per inch of soil for each major soil

layer. The capacity varies, depending on soil

properties that affect the retention of water and the

depth of the root zone. The most important properties

are the content of organic matter, soil texture, bulk

density, and soil structure. Available water capacity is

an important factor in the choice of plants or crops to

be grown and in the design and management of

irrigation systems. Available water capacity is not an

estimate of the quantity of water actually available to

plants at any given time.

Soil reaction is a measure of acidity or alkalinity and

is expressed as a range in pH values. The range in pH

of each major horizon is based on many field tests. For

many soils, values have been verified by laboratory

analyses. Soil reaction is important in selecting crops

and other plants, in evaluating soil amendments for

fertility and stabilization, and in determining the risk of

corrosion.

Shrink-swell potential is the potential for volume

change in a soil with a loss or gain in moisture. Volume

change occurs mainly because of the interaction of

clay minerals with water and varies with the amount

and type of clay minerals in the soil. The size of the

load on the soil and the magnitude of the change in

soil moisture content influence the amount of swelling

of soils in place. Laboratory measurements of swelling

of undisturbed clods were made for many soils. For

others, swelling was estimated on the basis of the kind

and amount of clay minerals in the soil and on the

basis of measurements of similar soils.

If the shrink-swell potential is rated moderate to

very high, shrinking and swelling can cause damage

to buildings, roads, and other structures. Special

design is often needed.

Shrink-swell potential classes are based on the

change in length of an unconfined clod as moisture

content is increased from air-dry to field capacity. The

classes are low, a change of less than 3 percent;

moderate, 3 to 6 percent; high, 6 to 9 percent; and

very high, greater than 9 percent.

Erosion factor Kw indicates the susceptibility of a

soil to sheet and rill erosion by water. Factor Kw is one

of six factors used in the Universal Soil Loss Equation

(USLE) to predict the average annual rate of soil loss

by sheet and rill erosion in tons per acre per year. The
Curry County, Oregon 339

estimates are based primarily on percentage of silt,

sand, and organic matter (up to 4 percent) and on soil

structure and permeability. Values of Kw range from

0.02 to 0.64. Other factors being equal, the higher the

value, the more susceptible the soil is to sheet and rill

erosion by water.

Erosion factor T is an estimate of the maximum

average annual rate of soil erosion by wind or water

that can occur without affecting crop productivity over

a sustained period. The rate is in tons per acre per

year.

Wind erodibility groups are made up of soils that

have similar properties affecting their resistance to

wind erosion in cultivated areas. The groups indicate

the susceptibility of soil to wind erosion. The soils

assigned to group 1 are the most susceptible to wind

erosion, and those assigned to group 8 are the least

susceptible.

Organic matter is the plant and animal residue in

the soil at various stages of decomposition. In the

table, the estimated content of organic matter is

expressed as a percentage, by weight, of the soil

material that is less than 2 millimeters in diameter.

The content of organic matter in a soil can be

maintained or increased by returning crop residue to

the soil. Organic matter affects the available water

capacity, infiltration rate, and tilth. It is a source of

nitrogen and other nutrients for crops.

Soil and Water Features

Table 17 gives estimates of various water features.

The estimates are used in land use planning that

involves engineering considerations.

Hydrologic soil groups are based on estimates of

runoff potential. Soils are assigned to one of four

groups according to the rate of water infiltration when

the soils are not protected by vegetation, are

thoroughly wet, and receive precipitation from longduration storms.

The four hydrologic soil groups are:

Group A. Soils having a high infiltration rate (low

runoff potential) when thoroughly wet. These consist

mainly of deep, well drained to excessively drained

sands or gravelly sands. These soils have a high rate

of water transmission.

Group B. Soils having a moderate infiltration rate

when thoroughly wet. These consist chiefly of

moderately deep or deep, moderately well drained or

well drained soils that have moderately fine texture to

moderately coarse texture. These soils have a

moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when

thoroughly wet. These consist chiefly of soils having a

layer that impedes the downward movement of water

or soils of moderately fine texture or fine texture.

These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate

(high runoff potential) when thoroughly wet. These

consist chiefly of clays that have a high shrink-swell

potential, soils that have a high water table, soils that

have a claypan or clay layer at or near the surface,

and soils that are shallow over nearly impervious

material. These soils have a very slow rate of water

transmission.

If a soil is assigned to two hydrologic groups in the

table, the first letter is for drained areas and the

second is for undrained areas.

Flooding, the temporary inundation of an area, is

caused by overflowing streams, by runoff from

adjacent slopes, or by tides. Water standing for short

periods after rainfall or snowmelt is not considered

flooding, and water standing in swamps and marshes

is considered ponding rather than flooding.

The table gives the frequency and duration of

flooding and the time of year when flooding is most

likely.

Frequency, duration, and probable dates of

occurrence are estimated. Frequency is expressed as

none, rare, occasional, and frequent. None means that

flooding is not probable; rare that it is unlikely but

possible under unusual weather conditions (the

chance of flooding is nearly 0 percent to 5 percent in

any year); occasional that it occurs, on the average,

once or less in 2 years (the chance of flooding is 5 to

50 percent in any year); and frequent that it occurs, on

the average, more than once in 2 years (the chance of

flooding is more than 50 percent in any year).

Common is used when the occasional and frequent

classes are grouped for certain purposes. Duration is

expressed as very brief if less than 2 days, brief if 2 to

7 days, long if 7 days to 1 month, and very long if

more than 1 month. Probable dates are expressed in

months. About two-thirds to three-fourths of all flooding

occurs during the stated period.

The information is based on evidence in the soil

profile, namely thin strata of gravel, sand, silt, or clay

deposited by floodwater; irregular decrease in organic

matter content with increasing depth; and little or no

horizon development.

Also considered are local information about the

extent and levels of flooding and the relation of each

soil on the landscape to historic floods. Information on

the extent of flooding based on soil data is less

specific than that provided by detailed engineering

surveys that delineate flood-prone areas at specific

flood frequency levels.

High water table (seasonal) is the highest level of a
340

saturated zone in the soil in most years. The estimates

are based mainly on observations of the water table at

selected sites and on the evidence of a saturated

zone, namely grayish colors or mottles (redoximorphic

features) in the soil. Indicated in the table are the

depth to the seasonal high water table; the kind of

water table—that is, perched, apparent, or artesian;

and the months of the year that the water table

commonly is high. A water table that is seasonally high

for less than 1 month is not indicated in the table.

An apparent water table is a thick zone of free water

in the soil. It is indicated by the level at which water

stands in an uncased borehole after adequate time is

allowed for adjustment in the surrounding soil. A

perched water table is water standing above an

unsaturated zone. In places an upper, or perched,

water table is separated from a lower one by a dry

zone. An artesian water table is under hydrostatic

head, generally below an impermeable layer. When

this layer is penetrated, the water level rises in an

uncased borehole.

Two numbers in the column showing depth to the

water table indicate the normal range in depth to a

saturated zone. Depth is given to the nearest half foot.

The first numeral in the range indicates the highest

water level. A plus sign preceding the range in depth

indicates that the water table is above the surface of

the soil. “More than 6.0” indicates that the water table

is below a depth of 6 feet or that it is within a depth of

6 feet for less than a month.

Table 18 gives estimates of various soil features.

The estimates are used in land use planning that

involves engineering considerations.

Depth to bedrock is given if bedrock is within a

depth of 5 feet. The depth is based on many soil

borings and on observations during soil mapping. The

rock is either soft or hard. If the rock is soft or

fractured, excavations can be made with trenching

machines, backhoes, or small rippers. If the rock is

hard or massive, blasting or special equipment

generally is needed for excavation.

A cemented pan is a cemented or indurated

subsurface layer within a depth of 5 feet. Such a pan

causes difficulty in excavation. Pans are classified as

thin or thick. A thin pan is less than 3 inches thick if

continuously indurated or less than 18 inches thick if

discontinuous or fractured. Excavations can be made

by trenching machines, backhoes, or small rippers.

A thick pan is more than 3 inches thick if

continuously indurated or more than 18 inches thick if

discontinuous or fractured. Such a pan is so thick or

massive that blasting or special equipment is needed

in excavation.

Potential frost action is the likelihood of upward or

lateral expansion of the soil caused by the formation of

segregated ice lenses (frost heave) and the

subsequent collapse of the soil and loss of strength on

thawing. Frost action occurs when moisture moves

into the freezing zone of the soil. Temperature, texture,

density, permeability, content of organic matter, and

depth to the water table are the most important factors

considered in evaluating the potential for frost action. It

is assumed that the soil is not insulated by vegetation

or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in

winter are the most susceptible to frost action. Well

drained, very gravelly, or very sandy soils are the least

susceptible. Frost heave and low soil strength during

thawing cause damage mainly to pavements and other

rigid structures.

Risk of corrosion pertains to potential soil-induced

electrochemical or chemical action that dissolves or

weakens uncoated steel or concrete. The rate of

corrosion of uncoated steel is related to such factors

as soil moisture, particle-size distribution, acidity, and

electrical conductivity of the soil. The rate of corrosion

of concrete is based mainly on the sulfate and sodium

content, texture, moisture content, and acidity of the

soil. Special site examination and design may be

needed if the combination of factors results in a severe

hazard of corrosion. The steel in installations that

intersect soil boundaries or soil layers is more

susceptible to corrosion than steel in installations that

are entirely within one kind of soil or within one soil

layer.

For uncoated steel, the risk of corrosion, expressed

as low, moderate, or high, is based on soil drainage

class, total acidity, electrical resistivity near field

capacity, and electrical conductivity of the saturation

extract.

For concrete, the risk of corrosion is also expressed

as low, moderate, or high. It is based on soil texture,

acidity, and amount of sulfates in the saturation

extract.

The system of soil classification used by the

National Cooperative Soil Survey has six categories

(USDA 1975, USDA 1994). Beginning with the

broadest, these categories are the order, suborder,

great group, subgroup, family, and series.

Classification is based on soil properties observed in

the field or inferred from those observations or from

laboratory measurements. Table 19 shows the

classification of the soils in the survey area. The

categories are defined in the following paragraphs.

ORDER. Eleven soil orders are recognized. The

differences among orders reflect the dominant soilforming processes and the degree of soil formation.

Each order is identified by a word ending in sol. An

example is Inceptisol.

SUBORDER. Each order is divided into suborders

primarily on the basis of properties that influence soil

genesis and are important to plant growth or

properties that reflect the most important variables

within the orders. The last syllable in the name of a

suborder indicates the order. An example is Umbrept

(Umbr, meaning shade and thus dark, plus ept, from

Inceptisol).

GREAT GROUP. Each suborder is divided into great

groups on the basis of close similarities in kind,

arrangement, and degree of development of

pedogenic horizons; soil moisture and temperature

regimes; type of saturation; and base status. Each

great group is identified by the name of a suborder

and by a prefix that indicates a property of the soil. An

example is Haplumbrepts (Hapl, meaning minimal

horizonation, plus umbrept, the suborder of the

Inceptisols that has a udic moisture regime).

SUBGROUP. Each great group has a typic

subgroup. Other subgroups are intergrades or

extragrades. The typic subgroup is the central concept

of the great group; it is not necessarily the most

extensive. Intergrades are transitions to other orders,

suborders, or great groups. Extragrades have some

properties that are not representative of the great

group but do not indicate transitions to any other

taxonomic class. Each subgroup is identified by one or

more adjectives preceding the name of the great

group. The adjective Typic identifies the subgroup that

typifies the great group. An example is Typic

Haplumbrepts.

FAMILY. Families are established within a subgroup

on the basis of physical and chemical properties and

other characteristics that affect management.

Generally, the properties are those of horizons below

plow depth where there is much biological activity.

Among the properties and characteristics considered

are particle size, mineral content, soil temperature

regime, soil depth, and reaction. A family name

consists of the name of a subgroup preceded by terms

that indicate soil properties. An example is loamyskeletal, mixed, mesic Typic Haplumbrepts.

SERIES. The series consists of soils within a family

that have horizons similar in color, texture, structure,

reaction, consistence, mineral and chemical

composition, and arrangement in the profile.

Soil Series and Their Morphology

In this section, each soil series recognized in the

survey area is described. Characteristics of the soil

and the material in which it formed are identified for

each series. A pedon, a small three-dimensional

area of soil, that is typical of the series in the survey

area is described. The detailed description of each

soil horizon follows standards in the “Soil Survey

Manual” (USDA 1993). Many of the technical terms

used in the descriptions are defined in “Soil Taxonomy”

(USDA 1975) and in “Keys to Soil Taxonomy” (USDA

1994). Unless otherwise indicated, colors in the

descriptions are for moist soil. Following the pedon

description is the range of important characteristics of

the soils in the series.

The map units of each soil series are described in

the section “Detailed Soil Map Units.”

Soil consists of layers of mineral or organic material

on the surface of the earth. Soil is formed by the

interaction of five basic factors—climate, living

organisms, parent material, topography, and time. The

physical and chemical processes that result from the

interaction of these factors determine the

characteristics and properties of a soil. The influence

of any one of these factors varies from place to place,

but the interaction of all the factors determines the

type of soil that forms.

The soils in this survey area have been greatly

influenced by climate. Moist marine air moving inland

from the Pacific Ocean moderates extremes in the

diurnal and annual air and soil temperature in winter

and summer. The result is a long but cool growing

season in the coastal areas, which make up the

isomesic zone, or fogbelt. Further inland, the direct

influence of marine air diminishes and the extremes in

air and soil temperature increase. These inland areas

have a shorter but warmer growing season.

The characteristics of the parent material greatly

influence the kinds of soil that form. Soils that formed

in colluvium and residuum derived from older Jurassic

metasedimentary and metavolcanic rock, such as

sandstone of the Dothan Formation and Colebrooke

schist, have properties such as a lower liquid limit,

higher plasticity and bulk density values, and a lower

cation exchange capacity in the surface layer (Baldwin

1981, Beaulieu 1976, Ramp and others 1977). Soils

that formed in colluvium and residuum derived from

younger Tertiary marine and nonmarine sedimentary

rock and marine volcanic rock, such as the Umpqua

Group of the Roseburg, Flournoy, and Lookingglass

Formations, have properties such as a higher liquid

limit, lower plasticity and bulk density values, and a

higher cation exchange capacity. Soils that formed in

colluvium and residuum derived from ultramafic rock,

such as serpentinite and peridotite, have less major

nutrients for plant growth and thus have a lower fertility

level, have an overall nutrient imbalance because of

the high content of magnesium and low content of

calcium and molybdenum, and have a high

concentration of toxic heavy metals, such as nickel

and chromium.

The topography of the survey area is dominantly

steep or very steep because the area encompasses

the highly faulted Klamath Mountain terranes of the

Triassic and Jurassic that abut to the north with

moderately high terranes of the Eocene. These

terranes have been modified along the coast by

wave-cut platforms, which are associated with past

high sea levels, that have been uplifted by tectonic

activity. Many of these platforms have also been

modified by dune activity, which has resulted in

additional topographic relief. The mouth of the

estuaries also has been topographically modified by

sand spits, beaches, and dunes.

The period of time parent material has been in

place influences the kinds of soil that have formed.

Soils that formed in recent alluvium on flood plains

exhibit minor profile development, such as a thin mollic

or umbric epipedon, a thin cambic horizon, and an

irregular decrease in organic carbon as a result of

frequent deposits of alluvium. Soils that formed in

older alluvium on terraces exhibit greater profile

development, such as a considerably thicker mollic or

umbric epipedon, an argillic horizon, and a regular

decrease in organic carbon. Soils on the coastal plain

terraces have been strongly influenced by the sandy

parent material of the old, stabilized dunes.

In this section, the factors of climate and living

organisms are discussed together and the factors of

time, topography, and parent material are discussed

under the headings “Geomorphic Surfaces and Soil

Development” and “Looney Unit and Soil

Development.” At the end of this section is a table that

lists the diagnostic features and horizons of the soils

on each geomorphic surface and on the Looney unit.

Climate and Living Organisms

Climate strongly influences soil formation by

controlling the chemical and physical reactions in soil.

Temperature and moisture influence the chemical and

physical nature of soil by influencing the rate of

chemical reactions, the weathering of minerals and

material in a soil horizon, and the transport of material

from one horizon to another. The kind of vegetation

that grows in an area and its rate of growth; the activity

and abundance of insects, animals, soil microbes, and

fungi; and the rate of accumulation and decay of

organic matter are all influenced by climate.

Living organisms, especially the higher plants, are

an active factor in soil formation. The changes they

bring about result from the life processes peculiar to

each organism. The kinds of organisms that live on

and in the soil are determined by climate, topography,

age of the soil, and parent material.

Plants actively influence soil formation by providing

a root system and cover that hold soil particles

together so that they are resistant to erosion.

Decomposition of leaves, twigs, roots, and the remains

of entire plants returns valuable organic matter to soil.

Plant roots also widen cracks in the underlying rock,

allowing water to penetrate. The uprooting of trees by

wind mixes soil layers, loosens the underlying

material, and moves weathered rock and mineral

material to the surface.

Organisms such as insects and earthworms, fungi

and other micro-organisms, and burrowing animals

actively influence the formation of soils. These

organisms accelerate the decomposition of organic

matter by consuming and digesting the remains of

plants. Bacteria, fungi, and other micro-organisms

hasten the weathering of rock into mineral soil

particles. Insects, micro-organisms, and earthworms

feed on organic matter on the surface and in the upper

few inches of the soil. They slowly, but continually, alter

the physical and chemical properties of organic matter

and aid in mixing it with mineral material. Small

animals burrow into the soil for shelter, mixing the

layers.

Three Major Land Resource Areas (MLRA) are in

the survey area—Northern Pacific Coast Range,

Foothills, and Valleys (MLRA 1); California Coastal

Redwood Belt (MLRA 4); and Siskiyou-Trinity Area

(MLRA 5) (USDA 1981). MLRA 1 has been subdivided

into the cooler coastal fogbelt and the warmer interior

mountain area.

Six major climate zones that greatly influence soil

genesis are recognized in the survey area. The

following table summarizes the climatic and

topographic ranges for each of these zones.

The isomesic zone, or coastal fogbelt, represents

climate zones 1 and 2. Fogbelt is a general term used

for the area that is influenced by fog, low clouds, and

cool, moist marine air in summer. It extends from the

Pacific Ocean to about 3 to 5 miles inland, or to the

first range of hills or mountains that tend to prevent the

low clouds and fog from moving further inland. Along

rivers and in low-lying areas, the fogbelt can extend as

far as 15 to 20 miles inland. Elevation in this zone

ranges from sea level to 1,300 feet. The soils have an

isomesic temperature regime and a udic moisture

regime (USDA 1975, USDA 1994).

Climate zone 1 extends from the Coos County line

to the Chetco River, at Brookings. The growing season

is year round. The soils in this zone are in general soil

map units 1, 3, 4, 6, and 7. They are represented by

the Coastal Fog vegetation zone (see “Vegetative

Diversity”).

Climate zone 2 extends from the Chetco River

south to the California State line. The growing season

is year round. The soils in this zone are in general soil

map units 2 and 5. They are represented by the

Redwood vegetation zone.

The abundant moisture and modified air and soil

temperature in the coastal fogbelt result in a long

growing season that allows for a large accumulation of

organic matter. The high rainfall in the fogbelt results in

extensive leaching of bases; therefore, the soils have

low base saturation. Conifers absorb bases but they

do not readily return bases to the soils, which further

contributes to the low base saturation of the soils.

Organic matter accumulates in the soils because the

cool temperatures slow down the rate of

decomposition. Aeric Tropaquepts, Fluventic

Humitropepts, and Typic Tropopsamments have

formed on the young surfaces, such as flood plains

and coastal dunes, in the fogbelt. Typic Haplohumults,

Typic Haplorthods, and Typic Humitropepts have

formed on the older surfaces, such as terraces and

coastal hills, where soil-forming factors have been

active for a much longer period of time.

In inland areas immediately adjacent to the coastal

fogbelt, climate zone 3 is at the lower elevations and

climate zone 4 is at the higher elevations. The soils

have a udic moisture regime. The soil temperature

regime is mesic at the lower elevations and frigid at

the higher elevations (USDA 1975, USDA 1994).

Climate zone 3 is typified by most of the lower and

middle elevation interior areas of the survey area. The

growing season is somewhat shorter and warmer than

that of the isomesic zone, and the soils dry out more in

summer. The soils in this zone are in general soil map

units 8, 9, 10, 11, 12, and 13. Progressing from north

to south, the soils are represented by the Western

Hemlock, Tanoak/Hemlock, and Coastal Tanoak

vegetation zones.

Climate zone 4 is typified by most of the higher

elevation peaks and ridges in the interior areas. The

growing season is short, and the soils dry out for brief

periods in summer. The soils in this zone are in

general soil map units 14 and 15. The soils in the

northern part are represented by the Cool Western

Hemlock vegetation zone, and those in the southern

part are represented by the Cool Douglas Fir zone.

Tree growth in this climatic zone is slower, and

damage to trees by wind, snow, and ice is common.

Precipitation in climatic zones 3 and 4 is high in

winter, and it increases as elevation increases. The

direct moderating effect of the cool, moist marine air

on air and soil temperature diminishes in these zones.

Because the high precipitation in winter results in

extensive leaching of bases, the soils have low base

saturation. Cold temperatures in this zone significantly

restrict the activity of micro-organisms. This results in

accumulations of organic matter that are thick enough

to allow an umbric epipedon to form in most of the

soils that are on stable or metastable landforms with

nearly level to moderately steep slopes. The

percentage of organic matter, however, is lower than

that of the soils in the fogbelt. Soils on active

landforms with steep or very steep slopes typically

have an ochric epipedon. An exception is those on

north aspects where enough organic matter has

accumulated for an umbric epipedon to form. Typic

Haplumbrepts and Pachic Haplumbrepts are

examples. On young surfaces, such as flood plains

and steep or very steep active mountainslopes,

Fluvaquentic Humaquepts, Fluventic Haplumbrepts,

Umbric Dystrochrepts, and Dystric Eutrochrepts have

formed. Physical weathering of the bedrock by frost

action, or the freezing and thawing of moisture, can

result in soils that have a high content of rock

fragments and are poorly developed. Lithic

Eutrochrepts are an example. On older surfaces, such

as stream terraces and moderately steep or steep

metastable mountainslopes, soil-forming factors have

been active for a much longer period of time. Some of

the soils on these surfaces, such as Ultic Hapludalfs

and Typic Haplohumults, have an argillic horizon and

others, such as Typic Haplumbrepts, do not. On the

oldest surfaces, such as the deeply dissected

remnants of the highest marine terraces and nearly

level to moderately steep stable mountainslopes, a

well-developed argillic horizon has formed in soils

such as Typic Haplohumults and Typic Palehumults.

On the less stable slopes, soils such as Typic

Haplumbrepts and Pachic Haplumbrepts have

developed.

East of the Coastal Tanoak vegetation zone, climate

zone 5 is at the lower elevations and climate zone 6 is

at the higher elevations. The soils of these interior

zones have a xeric moisture regime. The soils at the

lower elevations have a mesic temperature regime,
470 Soil Survey of

and those at the higher elevations have a frigid

temperature regime (USDA 1975, USDA 1994).

Climate zone 5 is typified by the lower and middle

elevation interior areas east of Agness, Illahe, and

Marial, along the Rogue and Illinois Rivers. This

climatic zone has been separated into three distinct

climatic and vegetative areas. At the lowest elevations

along the stream terraces of the inland rivers, the

growing season is long and plant growth begins early

in spring and continues until late in summer. The soils

are dry in summer for more than 90 consecutive days

following the summer solstice. In the lower elevation

foothills and mountains, the growing season is slightly

shorter than that of the adjacent terraces. Plant growth

begins early in spring and continues until midsummer.

The soils are dry in summer for 60 to 90 consecutive

days following the summer solstice. In the middleelevation foothills and mountains, the growing season

is distinctly shorter than that of the low-elevation

terraces. Plant growth begins late in spring and

continues until midsummer. The soils are dry in

summer for 45 to 60 consecutive days following the

summer solstice.

The soils in climate zone 5 are in general soil map

units 16, 17, and 18. They are represented by the

Interior Tanoak vegetation zone. Precipitation is

highest in winter, when it is sufficient to leach bases

resulting in soils that have low base saturation. The

direct effect of the cool, moist marine air is absent in

terms of modifying the air and soil temperature. This

zone generally supports fewer deciduous hardwood

trees and shrubs and more conifers. The high

precipitation and warmer temperature have resulted in

leaching of most bases and rapid decomposition of the

available organic matter. The flood plains and stream

terraces along the Rogue and Illinois Rivers have

more deciduous hardwood trees and shrubs in the

native plant community than do other areas of this

climatic zone. The deciduous vegetation contributes

large amounts of organic material to the soil. The

roots take up calcium and other bases and return

them to the soil annually through the leaves and twigs,

thus minimizing the loss of bases as a result of

leaching. The annual dieback of roots returns large

amounts of organic matter to the soil. These factors,

along with flooding and deposition of silt and sand

that are rich in organic matter, lead to the formation

of Mollisols, such as those found in Jackson County

(Almaraz 1993).

Cumulic Haploxerolls, Entic Ultic Haploxerolls, and

Dystric Xerochrepts have formed on young surfaces

such as flood plains and steep or very steep active

mountainslopes. On older surfaces, such as low

stream terraces and moderately steep or steep

metastable mountainslopes, soil-forming factors have

been active for a much longer period of time. Typic

Argixerolls, Ultic Haploxeralfs, and Typic Haploxeralfs,

which have an argillic horizon, formed on these

surfaces. Soils such as Dystric Xerochrepts formed

on the less stable slopes. On the oldest surfaces,

such as high stream terraces and nearly level to

moderately steep stable mountainslopes, the soils

have a well-developed argillic horizon. Examples are

Mollic Palexeralfs and Typic Palexerults, which

commonly are in proximity with soils such as Ultic

Haploxeralfs and Dystric Xerochrepts.

Climate zone 6 is typified by most of the higher

elevation peaks and ridges along the eastern margin

of the survey area. The growing season in this zone is

short, and the soils dry out for 45 to 60 consecutive

days following the summer solstice. The soils in this

zone are in general soil map unit 20 and parts of unit

14. They are represented by the Cold White Fir and

Shasta Red Fir vegetation zones.

High precipitation in winter results in extensive

leaching of bases and low base saturation of the soils

in this zone. Snow covers the area for extended

periods between November and June. Accumulations

of organic matter are limited, and more organic matter

is lost through oxidation. Soils that are on active

landforms with steep or very steep slopes, such as

Dystric Xerochrepts, typically have an ochric

epipedon. On north-facing slopes, however, soils

such as Typic Xerumbrepts have accumulated

enough organic matter to develop an umbric

epipedon. The percentage of organic matter in these

soils is less than that in the soils of the Cool Douglas

Fir and Cool Western Hemlock vegetation zones. The

soils in this climate zone have a short growing season.

Tree growth is slower, and damage to trees by wind,

snow, and ice is common.

Soils derived from ultramafic rock, such as

peridotite and dunite (igneous forms) and serpentinite

(metamorphic form), are throughout the survey area

(Kruckeberg 1964). They are in climate zones 1, 3, 4,

5, and 6 and correlate to general soil map units 11

and 19. Most of these soils are sterile and

unproductive as farmland or timberland; have

uncommon floras, with some endemic species; and

support vegetation that is in striking physiognomic

contrast to nonserpentinitic terrain (Whittaker 1954).

They are the most floristically diverse soils in the

survey area. The plant life varies greatly with location,

topography, and depth of the soil, but it commonly

is sparse or stunted. Many species seem to be

restricted to ultramafic soils, and many on adjacent

non-ultramafic soils are absent on ultramafic soils.

These characteristics commonly help to delineate
Curry County, Oregon 471

the geologic discontinuities in an ultramafic area

(Walker 1954).

The surface layer of the soils that formed in

ultramafic rock commonly is red, brown, or gray, and

the subsoil and substratum commonly are yellowish or

greenish in color. Since there are wide variations in the

composition of the parent rock, the content of calcium,

potassium, and heavy metals also varies considerably.

Ultramafic soils have reduced levels of total and

adsorbed calcium, elevated levels of magnesium, and

high levels of toxic heavy metals, such as nickel and

chromium. Even small variations in these levels may

have a marked effect on the ability of the soils to

support plant growth (Walker 1954).

The native vegetation includes many of the Pinus

jeffreyi plant associations. The soils in general soil

map unit 11 support mainly Jeffrey pine, western

white pine, knobcone pine, tanoak, lodgepole pine,

and Port Orford cedar with minor amounts of

Douglas fir scattered throughout (Atzet and Wheeler

1984). The soils in general soil map unit 19 support

mainly Jeffrey pine, sugar pine, knobcone pine,

tanoak, lodgepole pine, incense cedar, and

Port Orford cedar with minor amounts of Douglas fir

scattered throughout.

Precipitation generally is high in winter, and it

increases as elevation increases. Accumulations of

organic matter typically are minimal, except in areas

along or near fault zones or where seeps occur, such

as at the head of streams or where water drains from

bedrock joints. The accumulations are minimal in most

areas presumably because undesirable physical

characteristics such as steepness of slope,

shallowness of the soil mantle, gravelly to stony

textures that are low in content of clay, and

sparseness of vegetation result in continuous erosion

and reduced moisture and nutrient levels. Minimal

surface litter available for decomposition and

continuous erosion do not allow for the buildup and

incorporation of organic matter into the surface layer.

The properties of serpentinitic soils are highly variable;

however, these soils commonly have high base

saturation, have magnesium as the dominant

exchangeable cation, and have a low ratio of

exchangeable calcium to magnesium. In addition, the

level of available phosphorous and potassium is low

and soil reaction (pH) is neutral.

Ultramafic soils generally are on active landforms

because of their proximity and association with fault

zones. Unaltered peridotite exposures, such as those

at Iron Mountain, however, are rather stable and are

not associated with fault zones. Typically, there is a

strong correlation between fault zones and areas of

serpentinite and other serpentinitic rock within larger

exposures of peridotite. Ultramafic soils typically have

an ochric epipedon with minimal soil development;

however, some ultramafic soils have developed an

argillic horizon and stronger soil structure. On young

surfaces in the udic soil moisture regime, such as

nearly level to very steep mountainslopes, Dystric

Eutrochrepts and Lithic Eutrochrepts have formed in

the mesic and frigid soil temperature regimes. In the

isomesic soil temperature regime, where the climatic

extremes involved in the weathering process are

absent, Typic Hapludolls and Lithic Hapludolls have

formed. Loamy-skeletal soils typically form in areas of

highly fractured serpentinitic peridotite that contains

many thin veins of stable serpentine minerals and

weathers to loamy textures with a high content of rock

fragments.

In the xeric soil moisture regime, Dystric

Xerochrepts, Typic Xerochrepts, and Lithic

Xerochrepts have formed on metastable or active

mountainslopes. On older surfaces such as stable

mountainslopes, where soil-forming factors have been

active for a much longer period of time, some soils

have developed an argillic horizon. Mollic Haploxeralfs

and Ultic Haploxeralfs are examples. These soils are

derived from the less weathered peridotite in the

survey area.

Geomorphic Surfaces and Soil

Development

Geomorphologists and others have identified,

studied, and mapped the coastal and valley

geomorphic surfaces throughout Oregon and the

Pacific Northwest (Balster and Parsons 1968,

Balster and Parsons 1969, Gelderman 1970,

Gelderman and Parsons 1972, Glasmann and Kling

1980, Glasmann and others 1980, Goldin and

Parsons 1983, Hoppe 1989, Nettleton and others

1982, Parsons and others 1970, Parsons and

Herriman 1976, Parsons and others 1981,

Reckendorf 1993, Reckendorf and Parsons 1966).

They have also studied soil-geomorphic relationships

in mountainous terrain (Balster and Parsons 1965a,

Balster and Parsons 1965b, Parsons 1978,

Parsons and Balster 1966, Parsons and Herriman

1975). The geomorphic surfaces along the coastal

margin of Oregon and further inland along the

contiguous river valleys range in geologic age from

recent Holocene to early Pleistocene, and they

represent a sequence of landscape development.

A complete sequence of the geomorphic surfaces

was recognized in the survey area. Following is a list

of the geomorphic surfaces in this sequence, from
472 Soil Survey of

youngest to oldest. In italics are the coastal marine

surface names (fig. 26).

Recent to late Holocene flood plains and coastal

dunes

Horseshoe and Ingram surfaces (Balster and

Parsons 1968)

Late to early Holocene marine and low stream

terraces

Tenmile and Winkle surfaces (Balster and Parsons

1968)

Latest Pleistocene lower marine terraces and

intermediate stream terraces

Whiskey Run and Senecal surfaces (Griggs 1945,

Balster and Parsons 1968)

Late Pleistocene middle marine terraces

Pioneer and Dolph surfaces (Griggs 1945, Balster

and Parsons 1968)

Middle Pleistocene upper marine terraces

Seven Devils and Eola surfaces (Griggs 1945,

Balster and Parsons 1968)

Early Pleistocene highest marine terraces

Griggs surface (Griggs 1945)

In this section, the geomorphic surface names

developed for the Willamette Valley in Oregon are

used because these surfaces were visually correlated

to the survey area. The step sequence of geomorphic

surfaces that occurs in the Willamette Valley is

essentially the same as that of the survey area, with

essentially equivalent ranges in age and degree of soil

development.

Transects and traverses of these geomorphic

surfaces during soil mapping revealed considerable

variations in elevation and the probability that at a

minimum more than one episode of terrace

development has occurred on the higher terrace

levels. This is evidenced by the presence of at least

one terrace strandline, or past sea level. Past sea

levels derived from geologic records of abandoned or

relict marine shorelines, such as the Whiskey Run or

Pioneer terrace, comprise a datum for measuring

long-term crustal movement by bracketing the rate of

uplift within generalized periods of time. Pleistocene

and Holocene strandlines commonly are evidence of

past seismic episodes. Evidence in the strandlines,

such as buried peat layers within sandy horizons or

drowned trees in lakes or bays, reveals the

periodicity of earthquakes. Correctly interpreting

these relict strandlines leads to a more thorough

understanding of coastal tectonics and

paleoseismicity in coastal regions and ultimately

helps to forecast future seismic events.

Recent to late Holocene flood plains and coastal

dunes (Horseshoe and Ingram surfaces)

In this survey area, the recent to late Holocene

flood plains consist mainly of generally broad tidal

flood plains at the mouth of major streams and

narrow beaches along the Pacific Ocean. These

Holocene flood plains have low relief and include the

stream channel and associated features, such as

point bar deposits, channel fillings, abandoned

meanders, and tidal flats. Unless these areas are

protected by dikes and effective tidegates, they are

subject to frequent inundation during high tide.

Isomesic Aeric Tropic Fluvaquents such as Bayside

soils are typical of those that formed in the sediment

associated with the recent to late Holocene flood

plains.

The Horseshoe surface is the lower of two flood

plains along the alluvial valleys. It generally is

considered to be within the annual flood plain. This

surface probably began to develop after the survey

area had been settled, as evidenced by metal artifacts

found in the alluvium associated with the surface

(Balster and Parsons 1968, Parsons and others 1970,

Parsons and Herriman 1976). Isomesic Aeric

Tropaquepts such as Pistolriver soils and mesic

Fluvaquentic Humaquepts such as Quosatana soils

are typical of those that formed on these low flood

plains. Miscellaneous areas, which have essentially no

soil material and support little or no vegetation, also

occur on the Horseshoe surface. An example is

Riverwash, which is along the interior alluvial river

valleys. It consists of unstabilized sandy, silty, clayey,

or gravelly sediment that is flooded, washed, and

reworked frequently by rivers or streams. Riverwash is

the most extensive miscellaneous area recognized on

the Horseshoe surface.

The Horseshoe surface is subject to frequent

flooding, thus, it exhibits minimal soil development. An

irregular decrease in the content of organic carbon as

a result of frequent deposits of alluvium is typical of

the Fluvaquentic subgroups. The Aeric subgroups

either have ground water at a somewhat lower depth

or have shorter intervals when the entire soil is

saturated. In the xeric moisture regime within the

interior of the survey area, along the flood plains of

the Rogue and Illinois Rivers, only very minor areas

of soils representative of this surface were observable

and none were of sufficient size to be delineated at

the scale used for this survey. These areas were

correlated into the more extensive Ingram (Eagle

Point) surface.

The Ingram surface, or higher flood plain, consists

of undulating topography with bar-and-channel relief

that is a result of streams overflowing their banks.
Curry County, Oregon 473

Flooding is less frequent on this surface, and the soils

have had time to develop a somewhat more strongly

expressed umbric epipedon and cambic horizon.

Isomesic Fluventic Humitropepts such as Bagness

soils and mesic Fluventic Haplumbrepts such as

Kirkendall soils are typical of those that formed on

this higher flood plain. An irregular decrease in the

content of organic carbon is typical of the Fluventic

subgroups on this surface, which indicates that most

of the alluvial material recently was deposited by

water. Along the interior alluvial river valleys of the

Rogue and Illinois Rivers, mesic Cumulic

Haploxerolls such as Evans soils formed in loamy

alluvium.

The coastal dunes are represented by isomesic

Typic Tropopsamments such as Frankport and

Waldport soils. These soils formed in recently

stabilized eolian sandy material that is associated with

late Holocene dunes, and they exhibit minimal soil

development. In areas where these soils are under a

canopy of trees and shrubs, a transitional AC horizon

has formed. The Frankport soils consist of black sand

weathered from rock of the Klamath Mountains that

contains an abundance of heavy minerals. These soils

generally are more than 50 percent chromite,

magnetite, and illmenite, and they have only minor

amounts of quartz and feldspar minerals. The color of

these soils, particularly that of the subsoil, exhibits a

strong lithochromic influence. These soils are of some

economic importance as a possible source of

chromite. The Waldport soils have a high amount of

quartz and feldspar minerals, are light in color and

weight, and have a thin surface layer that is dark

colored as a result of an accumulation of organic

matter. These soils are on beaches, modern foredunes

along the beaches, and modern dunes on higher

coastal terraces. Generally, the Waldport soils are

north of Cape Blanco and the Frankport soils are to

the south. The Waldport soils do not have the

erosional and depositional influence of the Rogue

River and other major rivers that drain the Klamath

Mountains province.

A thin-surface phase of the Frankport and Waldport

soils was mapped on foredunes. The organic matter

content and soil development are minimal on the

foredunes as compared to the higher stabilized dunes.

All of the foredunes in the survey area have formed in

about the last 50 to 60 years. These areas are

associated with the introduction of European

beachgrass (Ammophila arenaria), which is vigorous

enough to grow up through the sand deposited in

winter to form new foredunes above the beach. The

soils on the foredunes may exhibit a dark-colored

subsoil, but the dark color is a result of the

lithochromic influence of the black sand rather than

increased soil development. There are also foredunes

associated with spits near the mouth of most of the

rivers in the survey area. These foredunes are not

always readily observable; thus, identification of them

from the adjacent geomorphic surfaces, such as the

Tenmile and Winkle surfaces, is complex. The

complexities of recent foredune formation being

superimposed over the process of coastal terrace

formation is illustrated by an area in the northern part

of the survey area. The foredunes in the Floras Lake

area, south of Langlois, are primarily on the shoreline

edge of the identified Tenmile geomorphic surface

(Nettleton and others 1982). Once a wave-cut platform

with an overlay of sandy material or other beach and

dune material occurs above sea level, such as the

Tenmile surface, wind erosion can remove sandy

sediment down to the level of the water table. Behind

the foredune, wind erosion essentially scours the area

down to the level of the water table in winter, creating

a wet interdune area, or deflation plain. Isomesic Typic

Psammaquents such as Heceta soils are in these

interdunal depressions. If these wet areas are

contiguous to streams, they also tend to receive

deposits of finer textured material during periods of

overbank flow. If these areas are at the mouth of

coastal rivers and streams, they can become

contiguous with tidal areas. The coastal terrace, or the

Tenmile surface, frequently is modified by wind

erosion, overbank deposition from streams, and tidal

deposition, making it indiscernible where the terrace

actually begins. During dry periods in summer, the

volume and level of water in the rivers drop because of

the lack of precipitation and a sand bar gradually

builds up at the mouth of most of the coastal streams

to a height sufficient to block off the stream channel

from the ocean.

The younger stabilized dunes in the survey area are

primarily on the higher Pioneer and Seven Devils

coastal terraces. These types of dunes are parabolic in

shape. They develop in areas where there is a

considerable amount of sand, a wind source that is

dominantly unidirectional, and vegetation along the

sides of the dunes that concentrates the wind.

Historically, in the high wind area along the southern

coast, it appears that sand from the beach has blown

onto the coastal terraces throughout the year. This

sand typically is high in content of quartz and feldspar

minerals, which are lighter in weight and more easily

transported by strong winds. Since these dunes are

cut off from the supply of sand from the beach, the

winds take sand from the back, or older, part of the

dune and move it forward to the younger tip of the

dune. By this process, the dunes slowly move across

these higher coastal terraces. The sandy soils of these

dunes have only limited time for soil development to

occur until they are disturbed again. Younger dunes, in

contrast to unaltered recent dunes, are slightly

weathered. They have higher base status and humus

levels. Continual weathering and leaching under the

cool, humid oceanic climate depletes the base status

of the soils and increases acidity (Jenny and others

1969). There could be hundreds or thousands of

years between disturbances, allowing some soil

formation to take place. This is the process through

which isomesic Typic Haplorthods such as Bullards

soils have formed.

It is important to understand that the southern

Oregon Coast probably is unique with regard to sand

blowing from the beach onto the coastal terraces

throughout the year. One study indicated that in most

areas along the Oregon Coast the foredunes build to a

height of about 30 feet. At about that height, the sand

tends to blow parallel to the face of the foredune,

causing aggradation and widening on the beach side.

This cuts off the supply of sand to the landward areas.

In this survey area, however, this does not hold true.

It appears that the foredunes are much higher than

30 feet, and the modern sand accumulation is

occurring on the coastal terraces as well as on the

beach. This is attributed to the particularly highvelocity, dominantly southwesterly wind on the

southern Oregon Coast in winter. The wind blows

substantial quantities of sand onto the Whiskey Run,

Cape Blanco, and Pioneer terraces.

Late to early Holocene marine and low stream

terraces (Tenmile and Winkle surfaces)

The Tenmile geomorphic surface is in the

northwestern corner of the survey area, west of

Langlois (Nettleton and others 1982). This is the

primary wetland area in the northern part of the

survey area. Other areas of this surface occur as

remnant lowlands intermingled with flood plains, from

Langlois south to Pistol River. These areas are inland,

immediately adjacent to foredunes and the associated

deflation plain along the western margin of the survey

area.

The main physiographic feature of the Tenmile

surface is the bar-and-channel topography associated

with an abandoned flood plain or lowland area. The

early Holocene sediment associated with the Tenmile

surface consists of very deep, fine textured estuarine

deposits of marine clay with a mantle of silty alluvium.

In the convex landscape positions (bar), the alluvium

has been in place long enough for initial weathering
Curry County, Oregon 475

and formation of a weakly expressed cambic B

horizon. Isomesic Typic Tropaquepts such as Chetco

soils have formed in the finer textured material in

these positions. Isomesic Aquentic Haplorthods such

as Yaquina soils are in slightly convex interdunal

positions adjacent to the deflation plain. These soils

have been stable long enough to form a thin albic

horizon at the soil surface and a cambic horizon in the

subsoil, which has weakly cemented iron nodules and

very thin lenses of minimal cementation throughout. In

the concave landscape positions (channel), the

alluvium is recent enough that soil development is

minimal and a cambic horizon has not formed. The

A horizon exhibits some soil development consisting of

minimal incorporation of organic matter. Isomesic

Tropic Fluvaquents such as Langlois soils have formed

in the channel positions on this surface. Wood

fragments collected at a depth of 3 to 4 feet from the

clayey substratum of Langlois soils in channel

positions on the Ingram surface transitioning onto the

Tenmile surface were dated at 2,275 years before

present (plus or minus 50 years). This gradation at the

interface of the Ingram flood plain surface onto the

slightly higher Tenmile marine terrace surface

correlates with an established date of 5,280 years

before present (plus or minus 270 years) for the

equivalent Winkle surface from the Willamette Valley of

Oregon (Reckendorf and Parsons 1966). There is,

however, the possibility that what is being recognized

as the Ingram flood plain channel is perhaps actually

its coastal terrace equivalent. In other words, west of

Langlois there could be a young coastal terrace below

the Tenmile surface that has been dated at 2,275

years before present (plus or minus 50 years). A

relative age of the Tenmile surface has been

suggested as about 5,300 to 10,800 years before

present (Bockheim and others 1993), citing previous

work that indicated that a spodic horizon along the

Oregon Coast probably forms in 10,000 years or less

(Nettleton and others 1982).

Two terrace levels were recognized and associated

with the Winkle surface along the alluvial valleys of the

survey area. The lower terrace level is well expressed

along the Elk and Sixes Rivers. The higher level exists

only as terrace remnants of a formerly more extensive

surface that has been eroded away. These remnants

are near the ocean and in areas upstream along these

rivers for approximately 2 to 3 miles. Soils associated

with andic properties, such as high water holding

capacity, high content of organic carbon, high cation

exchange capacity (when buffered to pH of 7 or more),

low bulk density, high amounts of chemically

extractable iron and aluminum, and high phosphate

retention, are on both terrace levels along the coastal

stream systems (Hoppe 1989). These soils are absent

in the southern part of the survey area, however,

presumably because of tectonic activity and coastal

erosion. Quillamook soils exhibit characteristics typical

of andic properties.

Alluvium associated with the lower terrace of the

Winkle surface consists of deep, medium textured

material. Typic Humitropepts such as Logsden soils

have formed in this material at the western margin of

the survey area, in the coastal fogbelt along the Elk

and Sixes Rivers. The higher terrace consists of

medium textured to coarse textured alluvium, possibly

because of a higher energy alluvial environment at the

time of initial deposition or because of a difference in

mineralogy or intensity of weathering. Isomesic Alic

Pachic Melanudands such as Quillamook soils formed

in this material. Isomesic Typic Melanaquands such as

Euchre soils have formed in the coastal zone on the

higher terrace of the Winkle surface, where the

depressional areas have an elevated water table.

Along the Chetco and Winchuck Rivers and inland in

the survey area, the Winkle surface is dominantly one

terrace level that consists of deep, medium textured

alluvium derived from surrounding metasedimentary

mountains. In the coastal fogbelt, isomesic Typic

Humitropepts such as Ettersburg soils have

developed in a slightly warmer climate zone. In the

udic moisture regime, mesic Ultic Hapludalfs such as

Eilertsen soils have formed in convex positions along

the Sixes River. Typic Humaquepts such as Zyzzug

soils have formed in swales that have an elevated

water table.

A zone that has a xeric moisture regime is

recognized in the interior of the survey area, including

part of the Rogue River and all of the Illinois River.

Both of these rivers have only limited stream terraces

and flood plains along their courses. The Rogue River

begins in the Cascade Mountains and flows to the

Pacific Ocean, grading to its base level (sea level) at

Gold Beach. The Illinois River begins in the Klamath

Mountains of southern Oregon and flows into the

Rogue River at Agness, where it grades into a

common base level. Both rivers flow through steeply

dissected mountainous topography. In some places

the stream channels are confined by resistant

bedrock, and the waterway has a high-energy

gradient. In other areas where the bedrock is less

resistant and more easily eroded, the channels are

unconfined and the energy gradient is much lower. In

these areas the watercourse is allowed to meander

and deposit its bedload, creating an alluvial valley.

Where these alluvial deposits occur along the

Rogue River, such as at Big Bend, near Illahe, and at

Agness, the river is continuing to downcut its stream
476 Soil Survey of

channel to its base level while flowing toward the

ocean. It still has a high-energy gradient and is

fast moving.

Within this xeric zone, the soils on the Winkle

surface have formed in coarse textured mixed

alluvium. Soil development is limited to the formation

of a thick mollic epipedon and a moderately expressed

to strongly expressed cambic horizon. These soils

exhibit a thicker, darker-colored profile (more organic

matter) than those recognized by Parsons and

Herriman on about the equivalent geomorphic surface

upstream along the Rogue River in Jackson County

(Parsons and Herriman 1976). Well drained mesic

Pachic Haploxerolls such as Central Point soils are in

the bar positions, and poorly drained Typic

Endoaquepts such as Clawson soils are in swales that

have an elevated water table. Along the Illinois River

from Agness south to Oak Flat, the river has begun to

grade its base level to that of the Rogue River. In this

area, the river has a lower energy gradient and is

slower moving; thus, it has had more time to deposit

its bedload. The soils on the Winkle surface in this

area have formed in moderately fine textured and fine

textured alluvium. Well drained mesic Typic Argixerolls

such as Foehlin soils are in the convex positions, and

poorly drained Vertic Epiaquolls such as Cove soils

are in the depressional areas that have an elevated

water table. The Foehlin soils in this survey area

appear to occur on the same low terrace level as was

recognized and mapped as the TouVelle surface in

Jackson County (Parsons and Herriman 1976). The

lower energy gradient along the Illinois River is

conducive to the stability necessary for the

incorporation of organic matter into the surface layer

and the formation of an argillic horizon through

weathering and translocation of clay particles into

the subsoil. The Foehlin soils exhibit these

characteristics. This lower energy gradient also

results in a depositional environment needed for the

accumulation of clayey alluvium and development of

a Vertic subgroup, such as are characteristic of the

Cove soils.

Latest Pleistocene lower marine terraces and

intermediate stream terraces (Whiskey Run

and Senecal surfaces)

The coastal Whiskey Run surface occurs in such

limited extent in the survey area that it has been

correlated into the lowest level of the next higher

geomorphic surface, the Pioneer surface, for reasons

of practicality. The coastal Whiskey Run surface was

recognized in the soil mapping as a few small

delineations of the Chitwood soils (isomesic Aquic

Humitropepts). These soils are on marine terrace

remnants in the Sixes and Elk Rivers area, in the

northern part of the survey area, and along a narrow

coastal terrace north of Gold Beach. Figure 27

illustrates the relationship of the Tenmile, Whiskey

Run, and Pioneer surfaces. The coastal Whiskey Run

surface was also mapped along coastal river valleys

as the Senecal surface, consisting of deep deposits of

clayey material. An umbric epipedon, elevated organic

carbon levels in the surface layer, and a moderately

expressed to strongly expressed cambic horizon are

typical of the soils that formed along the cooler coastal

valleys of the survey area. Researchers have assigned

a relative age of 83,000 years before present (plus or

minus 5,000 years) to the Whiskey Run surface at

Coquille Point in Coos County (Muhs and others

1990), and others suggest a similar age of 80,000

years before present (plus or minus several thousand

years) for the Cape Blanco terrace equivalent

(Bockheim and others 1993). On the Senecal surface

along the coastal river valleys, a weakly developed

argillic horizon is typical of the soils that have low base

saturation because of the strong leaching environment

in convex areas with better internal soil drainage.

Examples are isomesic Typic Haplohumults such as

Ekoms and Winchuck soils. An umbric epipedon and

argillic horizon are typical of soils that formed on the

Senecal surface along the slightly warmer and drier

inland valley of the Sixes River. In this area, mesic

Aquic Haplohumults such as Chismore soils have

formed in the nearly level to slightly depressional

areas that have an elevated water table. Along the

Rogue and Illinois Rivers, in the warmest and driest

climate zone in the survey area, the soils have an

argillic horizon, an ochric epipedon, and moderate

base saturation. They have a xeric moisture regime.

Examples are mesic Ultic Haploxeralfs such as Abegg

soils.

Late Pleistocene middle marine terraces and

remnant high stream terraces (Pioneer and

Dolph surfaces)

As mapped by Griggs (Griggs 1945) and Beaulieu

(Beaulieu 1976), the coastal Pioneer geomorphic

surface in the survey area appears to have three

terrace levels associated with it and a variety of

landforms. Recent studies have added understanding

to the genesis and morphology of soils on this surface

and higher marine terraces in Coos and Curry

Counties, which ultimately will assist in the correct

interpretation of relative ages of these surfaces

(Adams 1984, Bockheim and others 1993, Hoppe

1989, Janda 1970, Kelsey 1990, Marshall 1991,

McInelly and Kelsey 1990, Muhs and others 1990,

Wehmiller and others 1977).
Curry County, Oregon 477

In general terms, these studies have documented

that the development of a soil profile, the content of

clay, and the levels of chemically extractable iron and

aluminum increase as the age of the higher surfaces

increases, thus indicating progressively older landform

development from the Whiskey Run surface to the

Griggs surface (Hoppe 1989). Several recent studies

determined that the thickness of the solum increased

as the age of the geomorphic surface along the Pacific

Coast increased (Aniku and Singer 1990, Hoppe

1989, Marshall 1991, Muhs 1982). Other research has

shown a close relationship between the content of clay

and depth to the maximum accumulations of clay and

the age of the geomorphic surface (Busacca 1987,

Harden and Taylor 1982, Hoppe 1989). Depth to

unoxidized, unaltered beach sand increased markedly

from younger to older terrace surfaces, both at Cape

Arago in Coos County and at Cape Blanco in Curry

County. The increase in depth to the C horizon reflects

the increased time of exposure to weathering and soil

formation (Marshall 1991). The depth to unoxidized

parent material increased as the age of the

geomorphic surface increased. Variations in particle

size and possibly mineralogy on individual terraces

may be a result of sorting by wave action during

deposition. In addition, the particle size of the

C horizon is coarser on the lowest terraces and it

becomes progressively finer on the higher terraces,

presumably a result of in situ weathering (Janda

1970).

The lowest level of the Pioneer surface has been

recognized as the Cape Blanco terrace (Bockheim

and others 1993, Kelsey 1990, Marshall 1991,

Wehmiller and others 1977). Sediment associated

with this surface consists of coarse textured to fine

textured material, which varies in location and

amount depending on the elevation of the terrace.

Soils on the Cape Blanco terrace formed in Holocene

478 Soil Survey of

to Recent dune material (fig. 28). These soils did not

develop in the underlying older terrace material as

evidenced by the fact that the soils and parent material

are not coextensive with the underlying terrace

deposits. In addition, chipping waste material stone

artifacts from earlier Native American cultures that

would likely date as Holocene or younger have been

found in the profile of the Ferrelo soils (isomesic Typic

Dystropepts) in two separate areas of the Cape

Blanco terrace in the survey area. Associated with the

Ferrelo soils on this terrace are the Gearhart soils

(Typic Dystropepts) and the previously mentioned

Frankport and Waldport soils on younger stabilized

dunes, generally adjacent to the beach. Accumulation

of organic matter in the surface layer, development of

an umbric epipedon, and formation of a cambic

horizon are the only morphological evidences of soil

development on the Cape Blanco terrace. The

Gearhart soils formed in eolian sand, are dominantly

sandy in texture, and tend to occur closer to the

younger stabilized dunes, if present, or nearer to the

ocean edge. The Ferrelo soils formed in moderately

coarse textured sediment underlain by unconsolidated

sandy material, are loamy in texture, have a thick,

dark-colored surface layer, and have a more

developed cambic horizon. Transects and traverses

made during mapping revealed areas where more

developed soils, such as those of the Bullards and

Bandon series (isomesic Typic Haplorthods), had

previously occurred on this terrace level. These older

soils have been truncated above the spodic horizon or

the ortstein layer, which is an iron-cemented zone

within the spodic horizon, and have been overlain by

dark brown loamy material typical of the Ferrelo soils.

Presumably, the constant strong winds of the southern

Oregon coast have scoured the surface layer of these

older soils down to a level of more resistant soil

material. Subsequent winds have redeposited other

Figure 28.—Area of the Cape Blanco terrace dipping northward toward Floras Lake, as viewed from Blacklock Point. Note the

modern dune at right on the coastal terrace.
Curry County, Oregon 479

more recent sandy eolian material on the eroded soil

profile. A relative age suggested for the Cape Blanco

terrace in the survey area is 80,000 to 90,000 years

before present (Bockheim and others 1993).

The middle terrace level is the classic Pioneer

geomorphic surface and is referred to as the Pioneer

terrace. It was first recognized by Griggs (Griggs

1945) and then used for correlation purposes by

others (Beaulieu 1976, Bockheim and others 1993,

Hoppe 1989, Janda 1970, Kelsey 1990, Marshall

1991). A variety of landforms and elevational ranges is

associated with this terrace. A basic knowledge of

plate tectonic theory is helpful in understanding the

elevational and landform relationships that occur on

the Pioneer geomorphic surface and higher coastal

terraces. According to the theory, the crust and upper

mantle of the earth are subdivided into a series of

semi-independent plates, each of which is moving

laterally in response to deep-seated activity in the

earth. Boundaries between the plates are sites of

sea-floor rises in areas of divergence; trenches, or

continental collisions in areas of convergence; and

transform faults or transcurrent faults (large-scale

strike-slip) in areas of parallel movement. In the

northeastern Pacific Basin, a relatively complex border

zone has developed between the Pacific Plate (floor of

the Pacific Ocean) and the North American Plate

(North American continent, Greenland, and the Arctic).

As the Pacific Plate moves north relative to the North

American Plate, movement is experienced along the

various faults and rises that separate the two plates.

There is pressure between the two plates when this

movement is opposed by the North American Plate,

and it continues to build up along the fault zones until it

is relieved by an earthquake. Associated with the

release of energy are displacements, called faults,

along planar surfaces. When an earthquake occurs,

energy is released along these fault lines through the

crustal structure of the earth (Beaulieu 1976).

Typically, one side of the fault zone uplifts and the

other side subsides, creating a step effect where there

previously was a uniform surface. In addition,

subduction of the Juan de Fuca Plate beneath the

North American Plate has forced the west coast

upward. Cape Blanco in Curry County, which is about

35 miles from the subduction zone trench, has the

fastest rate of uplift, about 1 inch every 3 years, on

the Oregon Coast (Orr and others 1992). This

tectonic movement and the ongoing processes of

erosion and sedimentation on the coastal terraces

make it difficult to understand the sequence in

landscape development that would otherwise be

apparent over time if only eustatic (changes in sea

level) separations of coastal terraces were involved.

Consequently, there are discrepancies in the relative

age of these terraces in published literature. Through

the techniques of aminostratigraphy and amino acid

dating, a relative age of 105,000 years before present

has been correlated to the Pioneer terrace at

Cape Blanco (Kelsey 1990, Muhs and others 1990).

The major part of the Pioneer terrace extends from

Port Orford north into Coos County. A typical area of

this surface occurs from the Sixes River north to

Blacklock Point and Floras Lake, encompassing

Cape Blanco State Airport, east of Cape Blanco. The

soils in this area formed in coarse textured to medium

textured eolian material overlying stratified marine

sediment of the late Pleistocene. Landforms include

dunal and dissected terrace components. Isomesic

Typic Haplorthods, such as Nelscott soils, have

formed dominantly on broad, dissected marine

terraces in areas where loamy textured, wind- or

water-deposited material overlies stratified marine

sediment. An iron-cemented ortstein layer has

developed at a moderate depth in these soils. Typic

Duraquods, such as Depoe soils, have formed in

depressional areas on this surface. These soils have

an ortstein layer at a shallower depth. The water table

is perched above this impermeable layer and is at or

near the surface. Both the Nelscott and Depoe soils

have an albic horizon. Typic Haplorthods, such as

Bullards soils, formed in sandy marine and eolian

material and are on the older, stabilized sand dune

deposits. The Bullards soils are younger than the

Nelscott and Depoe soils, which have an ironcemented layer within the spodic horizon. A longer

period of time is needed for this layer to become an

ortstein layer. Other soils that formed on this Pioneer

terrace in the northern part of the survey area include

Horseprairie soils (isomesic Andic Humitropepts),

which formed in moderately fine textured material

along the back margin of this surface. These soils

have andic properties such as a high water-holding

capacity, low bulk density, high cation-exchange

capacity, a high level of phosphate retention, a high

content of chemically extractable iron and aluminum,

and a high content of organic carbon, particularly in

the surface layer.

Soils that have a fine textured subsoil also are on

the Pioneer terrace. Because of the plate tectonics of

the west coast, soft claystone and siltstone have been

made into wave-cut platforms, which are constantly

being uplifted as coastal strath terraces (Palmer 1967).

Weathering and leaching of salts occurs rapidly under

the high-precipitation coastal climate. Where the strath

terraces were formed from siltstone or sandstone

rather than claystone, the content of clay in the soils

probably is lower. Because of erosion and deposition,
480 Soil Survey of

soils on wave-cut platforms may be younger than the

platform itself (Jenny and others 1969). Some

Inceptisols on this terrace formed from the weathering

in place of the underlying parent material of wave-cut

platforms, and they exhibit only minor relief across the

landscape. Grindbrook soils (isomesic Aquic

Humitropepts) formed in medium textured to

moderately fine textured material in convex positions.

They do not have an argillic horizon. Wadecreek

soils (isomesic Typic Haplohumults) formed in fine

textured alluvium in swales or other depressional

areas. These soils formed on a siltstone strath

terrace, and they appear to be of limited extent on

the Pioneer terrace.

On Harbor Bench, south of Brookings, soils that

have a thick, dark-colored surface layer and a welldeveloped argillic horizon are on a terrace that is

similar in age to the Pioneer terrace but is at a

considerably lower elevation. This area probably is a

subsided remnant of the Pioneer terrace and

possibly is associated with an old fault zone along

the Chetco River (Beaulieu 1976, Ramp and others

1977). In this area it appears that most of clay in the

soil profile is derived from the weathering of the

underlying wave-cut platform, which probably formed

in claystone or siltstone already high in content of clay

minerals. Since coastal southwestern Oregon has

such an active tectonic history, numerous episodes of

transport of eroded material from clayey soils on steep

side slopes in the uplands and adjacent higher coastal

terrace levels have contributed significant amounts of

finer textured alluvium to the soils on Harbor Bench.

Ultisols in this area include the Klooqueh soils

(isomesic Typic Palehumults) in nearly level to gently

sloping areas, Crofland soils (isomesic Aquic

Haplohumults) in nearly level areas, and Huffling soils

(isomesic Typic Umbraquults) in slightly concave

swales and other depressional areas and along

drainageways.

The highest terrace level associated with the late

Pleistocene coastal Pioneer geomorphic surface has

been recognized as the Silver Butte terrace (Bockheim

and others 1993, Janda 1970, Kelsey 1990, Marshall

1991). A relative age correlation of approximately

125,000 years before present is suggested by several

researchers (Bockheim and others 1993, Kelsey 1990,

Muhs and others 1990). Variations in the landform also

occur on this terrace. Some soils have developed in

coarse textured to medium textured eolian material

overlying older, stratified marine sediment, and others

have developed in place from the weathering of

siltstone and claystone wave-cut strath terraces with

deposits of more recent alluvium overlying the

weathered parent material. Bandon soils (isomesic

Typic Haplorthods), which have an iron-cemented

layer within the spodic horizon, are in broad dissected

areas on this marine terrace. These soils are in areas

where medium textured to moderately coarse textured,

older eolian material overlies the ortstein layer.

Wadecreek soils (isomesic Typic Haplohumults)

formed in fine textured alluvium and are in swales and

other depressional areas. The Wadecreek soils on the

Silver Butte terrace exhibit a greater degree of

development in the argillic horizon than do those on

the adjacent lower Pioneer terrace level.

Taxonomically, the soils on both of these terrace levels

are classified exactly the same, and they have similar

uses. Base saturation of the Wadecreek soils is low.

Bullards soils (isomesic Typic Haplorthods) formed in

sandy marine and eolian material and are on older,

stabilized dune deposits, which is reflected in the

development of a spodic horizon in the subsoil. These

soils are younger than the Bandon soils that have an

iron-cemented ortstein layer and the Wadecreek soils

that have a well-developed argillic horizon (fig. 29).

On the Cape Blanco, Pioneer, and Silver Butte

terraces, the loamy mantle of very dark brown to

yellowish brown soil material that overlies the spodic

horizon, ortstein layer, or other terrace and dune

material obscures the boundaries between

Inceptisols, Spodosols, and Ultisols. At a scale of

1:24,000, this makes soil mapping within the same

terrace level very difficult. As a result, complexes of

soils that have vastly differing soil genesis and

morphology were mapped. At a larger scale, these

soil-landscape relationships would be more apparent

and easier to depict on a map.

In inland areas, the Dolph geomorphic surface

consists of dissected remnants of high terraces along

several of the major stream systems in the survey

area. In the coastal fogbelt, soils such as those of the

Cunniff series (isomesic Typic Palehumults) have

formed. Further inland along these major streams,

soils such as those of the McCurdy series (mesic

Typic Palehumults) have formed. These soils are

typified by low base status as a result of a strong

leaching environment. Cunniff soils formed in the

cooler coastal valleys, and McCurdy soils formed in

the warmer interior valleys of the Coast Range. In the

hot and dry (xeric) interior valleys of the Klamath

Mountains, on high stream terraces along the Rogue

and Illinois Rivers, the soils generally are well

developed. The stability and relative old age of these

high terraces has allowed for pedogenesis to occur for

a longer period of time. The soils have moderate to

strong structure, a relatively high percentage of clay in

the B horizon, or an argillic horizon, indicating a

favorable weathering environment. Ruch soils (mesic
Curry County, Oregon 481

Mollic Palexeralfs) formed on these terraces in mixed

alluvium derived from metamorphic rock. Selmac soils

(mesic Ultic Haploxeralfs) formed on these terraces in

stratified, loamy and clayey alluvium derived from

mixed sources.

Middle Pleistocene upper marine terraces and

dissected remnants of high stream terraces

(Seven Devils and Eola surfaces)

The coastal Seven Devils geomorphic surface, as

mapped in this survey area, consists of erosional

remnants of a once extensive terrace level now highly

dissected and of limited extent (Griggs 1945). In the

more recent published studies, this surface is

recognized as the Indian Creek terrace (Bockheim

and others 1993, Janda 1970, Kelsey 1990, Marshall

1991). A proposed relative age of about 200,000 years

before present is suggested (Bockheim and others

1993, Kelsey 1990, McInelly and Kelsey 1990).

Figure 30 illustrates the relationship of the lower

Pioneer surface to the higher Seven Devils surface.

Two fault zones that bisect the Seven Devils

surface, the Beaver Creek and Battle Rock faults,

complicate the understanding of this terrace (Kelsey

1990). Because of the multiple landform

displacements and episodes of terrace development

and the many variations in soil-forming material,

including extremely weathered saprolite to fine sand to

consolidated sediment that can be classified as

sandstone and siltstone, numerous explanations of the

soil genesis on this surface may be possible.

The major landscape components recognized on

the Seven Devils surface are a marine terrace that has

minimal relief and on which Spodosols formed and an

area of more rolling topography that has moderate

relief and on which Ultisols formed. Joeney soils

(isomesic Typic Duraquods) formed in the flat terrace

positions in medium textured eolian material overlying

older, stratified marine sediment. An iron-cemented

layer in the spodic horizon is at a shallow depth in the

soil profile, and the water table is perched at or near

the surface above this layer. Joeney soils have an albic

horizon at the surface. Cunniff soils (isomesic Typic

Palehumults) formed in fine textured marine sediment

in the areas of rolling topography.

Below the spodic horizon and ortstein layer in the

Joeney soils on the Seven Devils surface is saprolitic

material that is finer in texture than is typical beneath

Spodosols on other marine terraces in the survey

area. It is assumed that this saprolitic material is from

Figure 29.—Typical landscape positions and parent material of the Bandon, Bullards, and Wadecreek soils on the Silver Butte

terrace.
482 Soil Survey of

a wave-cut platform that formed in fine textured rock,

such as mudstone and siltstone, that had been buried

by beach and dune sand but upon uplift quickly

weathered to saprolite or unconsolidated material. This

material appears to be very similar to the fine textured

material of an argillic horizon, but it does not have the

clay films to reflect a genetic origin of clay. A

discontinuity was recognized at the top of this finer

textured layer, and the material at this level and below

were considered to be evidence of a truncated

erosional surface, or strandline. This material is much

older, varies in thickness, and is primarily weathered

from saprolite or fine textured estuarine deposits such

as mudstone. The spodic horizon and ortstein layer,

which are believed to have formed in beach and dune

sand, vary in thickness over short distances (less

than 100 feet) and are not coextensive with the

wave-cut platform that formed in mudstone. The

weathered sandy material also overlies weathered

siltstone and sandstone, all of which are evidence of

a discontinuity below the ortstein layer. This

understanding and interpretation of landscape

development of the marine terraces in the survey area

is recognized as perhaps only one of several

possibilities for consideration and acceptance. It was

applied consistently throughout the survey area during

soil mapping and related fieldwork, and it is consistent

with fieldwork, mapping, and reconnaissance

observations made by soil scientists in more recent

progressive soil surveys in Lincoln and Tillamook

Counties in Oregon.

Inland in the coastal fogbelt, the Eola surface

consists of dissected remnants of high terraces along

several of the major stream systems in the survey

area. Cunniff soils (isomesic Typic Palehumults) have

formed on this surface in the cooler coastal valleys. In

the slightly warmer and drier inland areas to the east,

mesic Typic Palehumults, such as Edson, Honeygrove,

and Orford soils, are typical of soils associated with

the Eola surface. These soils have a udic moisture

regime. They formed in fine textured material and have

low base saturation as a result of the strong leaching

environment. In the hot and dry interior valleys of the

Klamath Mountains, on high stream terraces along the

Rogue and Illinois Rivers, mesic Typic Palexerults,

such as Pollard soils, have formed in mixed alluvium

derived from metamorphic rock. These soils have a

xeric moisture regime. They are well developed and

formed on stable surfaces, which allowed for

pedogenesis to occur for a longer period of time.

Early Pleistocene highest marine terrace (Griggs

surface)

The Griggs geomorphic surface consists of deeply

dissected erosional remnants of the oldest and highest

stable marine terrace in the survey area (Griggs

1945). Recent studies recognize this surface as the

Poverty Ridge terrace (Adams 1984, Bockheim and

Figure 30.—View of the city of Port Orford. The city is on the Pioneer geomorphic surface and is flanked on both sides by the higher

Seven Devils surface.
Curry County, Oregon 483

others 1993, Hoppe 1989, Janda 1970, Kelsey 1990,

Marshall 1991). No relative age correlations of this

terrace have been made to date; however, speculation

suggests possible ages ranging from 500,000 to

1 million years before present.

This surface exhibits considerable variations in

elevation and soil-forming material. Multiple episodes

of terrace development appear to have occurred on

this surface, as evidenced by more than one

observable terrace strandline. The soil-forming

material ranges from extremely weathered gravelcobble alluvium derived locally from the early

Cretaceous Rocky Point Formation (Koch 1966)

grading westward to marine sand and gravel (Kelsey

1990).

At least two landform components appear to be

associated with the Griggs surface, although distinct

terrace morphology is not readily apparent. The

components consist of a terrace level that has minimal

relief and on which Spodosols have formed and an

area of more undulating topography that has moderate

relief and on which Ultisols have formed. Cashner soils

(isomesic Typic Duraquods) have formed in the flat

terrace areas in medium textured eolian material

overlying much older, stratified marine sediment. An

iron-cemented layer is in the spodic horizon at a

moderate depth in the soil profile, and the water table

is perched above it. Cashner soils have an albic

horizon at the surface. Burnthill soils (isomesic Typic

Palehumults) formed in local alluvium and marine

sediment in the undulating areas. These soils have an

umbric epipedon, a thick argillic horizon, and low base

saturation. Both the Burnthill and Cashner soils have a

siliceous mineralogy classification at the soil family

level. These soils are more than 90 percent, by weight,

silica minerals such as quartz, chalcedony, and opal

and other extremely durable minerals that are resistant

to weathering and are in the 0.02- to 2.0-millimeter, or

silt- and sand-sized, fraction (USDA 1975, USDA

1994). The degree of profile development, increase in

content of clay, and level of extractable iron and

aluminum in these soils as compared to the highly

weathered Spodosols and Ultisols on the Seven Devils

and Griggs terraces indicate that these soils are

considerably older than those on the lower terraces

(Hoppe 1989). The rock fragments in the Burnthill

soils, in particular, exhibit the shape of gravel and

cobbles; however, the fragments are extremely

weathered and they can be crushed between the

fingers or easily cut with a knife or shovel.

Because of the limited extent of the remnant Seven

Devils and Griggs surfaces and the lack of a readily

apparent way to recognize and separate the soils and

the associated landscape components at a scale of

1:24,000, complexes of soils of highly differing soil

morphological features and genesis were mapped.

At a larger scale, these soil-landscape differences

would be more apparent and easier to depict on a

map.

Looney Unit and Soil Development

The Looney unit has no particular age connotation;

therefore, is not considered to be a geomorphic

surface. The terrain of the Looney unit is completely

dissected and is dominantly steeply sloping. Slopes

are more than 100 percent in some areas. Steep,

broken topography mapped as the Looney unit may

represent the steeply sloping escarpment present in

some areas between two geomorphic surfaces, or it

may make up large areas of mountainous terrain so

thoroughly dissected that the geomorphic surfaces are

not recognizable. Erosion is active on much of the unit,

and some areas have been subject to mass soil

movement (Parsons and Herriman 1975).

The variability in age of the Looney unit makes it

useful for geomorphic mapping of mountainous terrain.

This unit could be subdivided into several smaller

geomorphic units if it were mapped at a larger scale.

Three significant gradient breaks are apparent, and

they correspond to stable, metastable, and active

slopes (Parsons 1978). Small alluvial valleys also are

included in this unit. Soils in the Looney unit formed in

colluvium and residuum derived dominantly from

metasedimentary and metavolcanic rock of the

Klamath Mountains and from sedimentary and marine

volcanic rock of the Coast Range, including

sandstone, siltstone, mudstone, conglomerate, basalt

tuff and breccia, and pillow basalt flow. The

metasedimentary and metavolcanic rock is associated

with the Jurassic Dothan, Otter Point, Galice, and

Rogue Formations and the late Jurassic-early

Cretaceous Colebrooke Schist Formation and

ultramafic rock intrusions. The sedimentary and

marine volcanic rock is associated with the Tertiary

Umpqua assemblage of the Roseburg, Flournoy, and

Lookingglass Formations and minor amounts of the

Tyee Formation (Baldwin 1981, Ramp and others

1977).

In the following paragraphs, discussion of the

Looney unit is based on the isomesic, mesic, and

frigid soil temperature regimes recognized in the

survey area.

Isomesic zone

The Looney unit occurs in the isomesic zone, or

coastal fogbelt, at an elevation of 1,300 feet or less.

Both the Coast Range and Klamath Mountains are in
484 Soil Survey of

the northern part of the survey area, but only the

Klamath Mountains are in the southern part.

In the Coast Range, the Looney unit is typified by

Andic Humitropepts such as Templeton soils. These

soils formed on stable or metastable slopes in

colluvium and residuum derived from sedimentary

rock of the Umpqua Group. Andic soil properties are

evident in the surface layer.

In the Klamath Mountains in the northern part of the

survey area are five different rock types—the Early

Cretaceous Myrtle Group, including the Humbug

Mountain Conglomerate and Rocky Point Formation;

the Late Cretaceous Cape Sebastian sandstone and

Hunters Cove Formation; the Jurassic Dothan/Otter

Point Formation; the Jurassic Colebrooke Schist

Formation; and Jurassic ultramafic rock. In the

Cretaceous areas that have stable or metastable

slopes, Typic Haplohumults such as Bullgulch soils

have formed. On the Colebrooke Schist Formation,

soils such as those of the Desons series (Typic

Palehumults) and Watches series (Typic

Humitropepts) have formed. This formation is primarily

metasedimentary rock, or sedimentary rock that has

undergone slight to moderate metamorphism.

Sediment in the rock strata may range from mostly

sand with a low content of silt or clay (sandstone) to

mostly clay and silt with a low content of sand

(siltstone and mudstone). Characteristic of this

formation are the thin, linear and platy rock fragments

that weather from the varying strata (USDA 1993). The

channers correspond to gravel-sized fragments, and

flagstones correspond to cobble-sized fragments.

Areas where the rock strata are dominantly siltstone

and mudstone generally are on the more stable

landscapes, where soil development processes have

been ongoing for a longer period of time. Areas of

sandstone strata generally are on the metastable or

active slopes that have minimal soil development.

Even where the sandier strata are on stable slopes,

development is limited to loamy texture, brown color,

and formation of a cambic horizon, which are typical of

the Watches soils. On metastable or active slopes, the

colluvial material tends to be high in content of rock

fragments. Skeletal soils such as those of the

Calfranch and Capeblanco series (Typic

Humitropepts) have formed on these slopes. This

process of differential weathering, which consists of

more rapid and thorough weathering of one rock

stratum as compared to another adjacent stratum on

the same landscape, occurs primarily in the Jurassic

geologic formations. Presumably, this is because they

have been subjected to the processes of

metamorphism (heat and pressure), unlike the

younger rock strata, and have been intensely folded,

faulted, and thrust over each other to form the

present-day inconformities across the landscape. On

the Dothan/Otter Point Formation, Andic Humitropepts

such as Grassyknob, Reedsport, and Svensen soils

have formed on the stable or metastable slopes. Andic

soil properties are evident in the surface layer of these

soils. On metastable or active slopes, the colluvial

material commonly is high in content of rock

fragments. Skeletal soils such as those of the

Millicoma and Whaleshead series (Andic

Humitropepts) have formed on these slopes. The

extent of ultramafic rock in the coastal fogbelt is

limited. The ultramafic rock commonly is along faults

where seepage of fluids high in elemental bases

increases the base status of the soils and darkens the

surface layer. Mollisols such as Rustybutte soils (Typic

Hapludolls) and Sebastian soils (Lithic Hapludolls)

have formed in this rock. Because of the instability of

ultramafic rock, the colluvial material is high in content

of rock fragments. Skeletal soils generally develop in

this type of parent material. The soils have a

serpentinitic mineralogy classification because of the

nature of the parent material.

Only rock of the Klamath Mountains is in the

coastal fogbelt in the southern part of the survey area.

Soils such as those of the Loeb and Macklyn series

(Typic Haplohumults) are on stable slopes.

Vondergreen soils (Aquic Hapludults) are in

depressional areas and drainageways. Soils such as

those of the Bosland, Floras, Wedderburn, and Zwagg

series (Typic Humitropepts) have formed on the

metastable slopes. These soils are loamy, except the

Floras soils, which are fine textured; have an increase

in the content of rock fragments, although not enough

to be classified as skeletal; and are brown in color.

Skeletal soils such as those of the Dulandy series

(Typic Humitropepts) and the Guerin series (Lithic

Dystropepts) have formed on active slopes.

Mesic zone

To the east, in the Coast Range area in the

northern part of the survey area, the Looney unit is at

an elevation of 1,300 to 2,500 feet in the udic moisture

regime and at an elevation of as high as 3,000 feet in

the interior xeric moisture regime. In this area the unit

is typified by Andic Haplumbrepts such as Bohannon

and Preacher soils that formed on stable or

metastable slopes in colluvium and residuum derived

from sedimentary rock of the Umpqua Group. Andic

soil properties are evident in the surface layer of these

soils. These soils are loamy; have an increase in the

content of rock fragments, although not enough to be

classified as skeletal; and are brown in color. Skeletal

soils such as those of the Digger series (Dystric
Curry County, Oregon 485

Eutrochrepts) have formed on metastable or active

slopes.

In the Klamath Mountains area in the northwestern

part of the survey area are five different rock types—

the Early Cretaceous Myrtle Group, including the

Humbug Mountain Conglomerate and the Rocky Point

Formation; the Jurassic Dothan/Otter Point Formation;

the Jurassic Galice Formation; the Jurassic

Colebrooke Schist Formation; and Jurassic ultramafic

rock. Typic Palehumults such as Orford soils have

formed on stable or metastable slopes in the

Cretaceous areas. Soils such as those of the Edson

and Barkshanty series (Typic Palehumults) and the

Irma series (Umbric Dystrochrepts) have formed on

the Colebrooke Schist Formation. Areas of sandstone

strata that have minimal soil development commonly

are on the metastable or active slopes. Even on stable

slopes in areas where the sandier strata occur,

development is limited to loamy texture, brown color,

and formation of a cambic horizon, which are typical of

the Irma soils. Skeletal soils such as those of the

Deadline series (Umbric Dystrochrepts) and the

Nailkeg series (Typic Dystrochrepts) have formed on

the metastable or active slopes. Soils such as those of

the Skookumhouse and Hazelcamp series (Typic

Haplohumults) have formed on stable slopes of the

Dothan/Otter Point Formation. Typic Haplumbrepts

such as Colepoint and Crutchfield soils and Umbric

Dystrochrepts such as Fritsland and Bravo soils have

formed on metastable slopes of this formation. These

soils are loamy; have an increase in the content of

rock fragments, although not enough to be classified

as skeletal; and are brown in color. Skeletal soils such

as those of the Cassiday series (Umbric

Dystrochrepts), Grouslous series (Lithic

Dystrochrepts), Remote series (Typic Dystrochrepts),

and Umpcoos series (Lithic Eutrochrepts) have formed

on active slopes. These soils are loamy and are brown

in color. On north-facing slopes where accumulation of

organic matter in the surface layer occurs more

readily, soils such as those of the Milbury series (Typic

Haplumbrepts) have developed an umbric epipedon.

Soils such as those of the Honeygrove series (Typic

Palehumults) have formed on stable slopes of the

Galice Formation. Typic Palehumults such as Shivigny

soils have formed on metastable slopes of this

formation. On stable to active landscapes underlain by

ultramafic rock, the soils typically are loamy, have an

ochric epipedon and a cambic horizon, and are

skeletal. Examples are the Greggo series (Lithic

Eutrochrepts) and the Mislatnah and Serpentano

series (Dystric Eutrochrepts). Redflat soils (Dystric

Eutrochrepts) are on stable or metastable slopes in

areas of ultramafic rock. The surface layer of the soils

that formed in ultramafic rock typically is red in color;

however, the subsoil and substratum may range from

red to brown to gray, depending on how the rock

weathered into soil material. Soil reaction (pH) of

ultramafic soils typically is slightly acid or neutral.

These soils have a serpentinitic mineralogy

classification because of the nature of the parent

material.

Two very distinct landscape features are in the

coastal areas and the adjacent inland areas—the

Carpenterville Shear Zone and the open areas of

grassland within the forests.

The Carpenterville Shear Zone exhibits extensive

faulting in the Dothan and Otter Point Formations.

Transects and traverses made during mapping in this

zone revealed extensive areas of light-colored, almost

white, clayey subsoil material on stable to active

slopes. Because of the formation of clayey fault gouge

material, it is not uncommon to find associated with

fault zones narrow bands of soils that have a lightcolored subsoil that is high in content of clay. It is

uncommon, however, to find a shear zone that is

several miles wide, as is the Carpenterville Shear

Zone. The rock units in this zone are claystone and

siltstone. A large amount of darker colored clay

material is also in this zone. Because of all the rough

topography in the shear zone, the soils derived from

fault gouge and the watershed clay weathered from

the underlying rock will likely produce extensive

valleyside alluvial clay material. Clayey soils that

formed in the shear zone on stable to active slopes

include those of the Hooskanaden series (isomesic

Andic Hapludalfs) at an elevation of less than 1,300

feet (fig. 31) and those of the Houstenader series

(mesic Aquic Argiudolls) at an elevation of 1,300 to

2,500 feet. These soils have a dark-colored surface

layer; a light-colored, very thick, clayey subsoil with an

elevated water table; and an argillic horizon. In the

northern part of the survey area, strata of mudstone

from the Dothan/Otter Point Formation that do not

have the usual interlayered sandstone bedding have

been highly sheared and deeply weathered. This

formation of clayey fault gouge material is similar to

that in the Carpenterville Shear Zone. Etelka soils

(Oxyaquic Dystrochrepts) and Whobrey soils (Aquic

Dystric Eutrochrepts) have formed in this area. They

have an ochric epipedon and a very thick, fine

textured cambic subsoil horizon with an elevated

water table.

Open areas of grassland within the forests are

throughout the mountainous areas on the

Dothan/Otter Point and Colebrooke Schist Formations.

Figure 9 illustrates an area of grassland in

 Adams Prairie. The soils in these areas
486 Soil Survey of

typically have an umbric epipedon and a cambic

horizon, are on ridgetops and south-facing slopes, and

support a grassland plant community. Agness soils

(Pachic Haplumbrepts) are on the Colebrooke Schist

Formation in nearly level to gently rolling areas.

Quailprairie soils (Pachic Haplumbrepts) are on the

Dothan Formation. On undulating to moderately steep

metastable slopes, Sixes soils (Pachic Haplumbrepts)

are on the Colebrooke Schist Formation and

Swedeheaven soils (Typic Haplumbrepts) are on

Dothan sandstone. Skeletal soils such as those of the

Goldbeach and Sankey series have formed on the

convex, active slopes of the Colebrooke Schist and

Dothan Formations, respectively. Annual dieback of

grass roots and incorporation of above-ground

vegetation have added large amounts of organic

matter to the surface layer of these soils. Annual

burning of the grassland by Native Americans for

many centuries incorporated additional organic

carbon into the topsoil, contributing to the

development of a thick, dark-colored umbric

epipedon. Other possible causes for these prairie

openings within the forests include manmade

clearings for livestock grazing, as evidenced on aerial

photographs by the rectangular shape of some of

these areas (Jones and Ferrero 1989), or perhaps

poor regrowth in old burned or landslide areas that

have thin soils and are on high-lying, dry, generally

south-facing slopes (Ferrero 1991).

Further east, in the xeric interior Coast Range area

in the northern part of the survey area, the Looney unit

is typified by Typic Palexerults such as Dumont and

Pollard soils. These soils are on stable or metastable

slopes. They formed in colluvium and residuum

derived from sedimentary rock of the Umpqua Group.

Base status in these soils is low because of the

elevated rainfall in winter and the strong leaching

environment. Typic Palexerults such as Acker and

Figure 31.—Area of Hooskanaden-Loneranch-Reinhart complex, 0 to 30 percent slopes, which is an area of grassland in the

Carpenterville Shear Zone. Millicoma-Whaleshead-Reedsport complex, 30 to 60 percent south slopes, is in the forested areas.
Curry County, Oregon 487

Shastacosta soils have formed on metastable slopes.

The Acker soils are moderately fine textured and have

an increase in the content of rock fragments but are

not skeletal, and the Shastacosta soils consist of

loamy colluvial material that is high in content of rock

fragments overlying a clayey subsoil (lithologic

discontinuity) that is similar to that in the Dumont and

Pollard soils. Skeletal soils such as those of the

Beekman series (Dystric Xerochrepts) and the

Vermisa series (Lithic Xerochrepts) are on active

slopes.

In the Klamath Mountains area in the northeastern

part of the survey area (mesic zone) are five different

Jurassic geologies—the Dothan/Otter Point Formation;

the Rogue Formation; diorite and related rock; gabbro,

metagabbro, and related rock; and ultramafic rock. On

stable or metastable slopes, the Looney unit is typified

by Typic Palexerults, such as Dumont soils, that

formed in colluvium and residuum derived from

metasedimentary rock. Soils such as those of the

Josephine series (Typic Haploxerults), Norling and

Speaker series (Ultic Haploxeralfs), and Colestine

series (Dystric Xerochrepts) have formed on

metastable slopes. Skeletal soils such as those of the

Atring and Kanid series (Dystric Xerochrepts) have

formed on active slopes. In diorite and related rock on

stable or metastable landscape positions, soils such

as those of the Sitkum and Steinmetz series (Dystric

Xerochrepts) have formed in medium textured to

coarse textured residual material. In gabbro,

metagabbro, and related rock, skeletal soils such as

those of the Fantz series (Pachic Ultic Haploxerolls)

and the Knapke series (Entic Ultic Haploxerolls) have

formed on metastable or active slopes. Dark soil color

is reflective of the parent material. On ultramafic rock,

soils that are clayey, have an ochric epipedon and

argillic horizon, and are skeletal are on stable to

active landscapes. Examples are the Pearsoll series

(Lithic Xerochrepts), the Dubakella series (Mollic

Haploxeralfs), and the Eightlar series (Typic

Xerochrepts). Gravecreek soils (Dystric Xerochrepts)

are loamy, are skeletal, and have a cambic horizon.

The surface layer of the soils that formed in ultramafic

rock typically is red in color; however, the subsoil and

substratum may range from red to brown to gray,

depending on how the rock weathered into soil

material. Soil reaction (pH) of ultramafic soils typically

is slightly acid to neutral. These soils have a

serpentinitic mineralogy classification because of the

nature of the parent material.

Frigid zone

The Looney unit is at an elevation of 2,500 to 5,500

feet in the udic moisture regime and 3,000 to 5,500

feet in the xeric moisture regime. Only rock of the

Klamath Mountains is in the frigid zone. Three Jurassic

geologies are in the udic moisture regime—the

Dothan/Otter Point Formation, the Colebrooke Schist

Formation, and ultramafic rock. Three Jurassic

geologies are in the xeric moisture regime—the

Dothan/Otter Point Formation, diorite and related rock,

and ultramafic rock.

Evidence of glaciation in the Klamath Mountains

has been observed and documented in both the udic

and xeric moisture regimes (Busby and Bestland

1992, Jones and Ferrero 1988, Jones and Ferrero

1989, Moring 1983). Glaciers in the Klamath

Mountains formed during several glacial episodes of

the late Pleistocene (Lee 1972, Sharp 1960). The

height of this glaciation occurred during the Wisconsin

stage, or about 75,000 years ago, when climatic and

atmospheric conditions were favorable for the

formation of extensive ice packs (Sharp 1960). Earlier

glaciation (100,000 years before present) probably

occurred in the Klamath Mountains, but evidence of

this has most likely been altered by later erosional

episodes (Woods 1988). The physiographic features

created by glaciers are determined by the thickness

and weight of the ice, the gradient of the slope, and

the characteristics of the bedrock, such as the jointing

patterns in hard rock (closely or widely spaced;

horizontal or vertical) and the resistance and

massiveness of rock such as granite (Woods 1988).

Glacial features of the Klamath Mountains in this

survey area include tarns, or glacial lake basins;

cirque lakes; steep headwalls; and moraines (Busby

and Bestland 1992, Jones and Ferrero 1988, Jones

and Ferrero 1989). Small, shallow glacial lakes and

tarns become meadows as a result of a gradual

process of encroachment of alluvial debris into the

shallow basin. During the initial stages of

sedimentation, the perimeter of the tarn becomes

swampy and vegetation becomes established. As the

process continues, the basin becomes filled with

alluvium and a grassy meadow is formed on the valley

floor (Woods 1988). Snow Camp Meadow, near Snow

Camp Mountain, is an example. Aquic Haplohumults

are on the undulating topography of the meadow, and

Cryaquepts are in the depressional areas and

drainageways. Many lakes in the Klamath Mountains

are in cirques carved by Pleistocene glaciers on

north- and northeast-facing slopes. Examples include

Game Lake, east of Gold Beach; Vulcan Lake,

northeast of Brookings; and Babyfoot Lake, on the

Curry-Josephine County line, west of Cave Junction.

These cirque lakes collect the snowmelt and runoff

from the surrounding higher elevations to form the

headwaters of the present-day streams (Woods 1988).
488 Soil Survey of

Steep headwalls in the north-facing drainageway of

Shasta Costa Creek, which is above 3,600 feet in

elevation, exhibit abundant evidence of erosion by

alpine glaciation (Jones and Ferrero 1988). Areas of

talus slopes are below the headwalls of rock

outcroppings. Haplumbrepts are in areas of gently

sloping to very steep topography, and Cryaquepts

formed in the erosional sediment deposited on the

floor of the tarn. Moraines are mounds of angular rock

and soil debris that are eroded and transported in ice

as a glacier moves downslope. As the glacier retreats,

debris from melting ice is left along the leading edge,

creating a terminal moraine, and along the sides,

creating a lateral moraine. Remnants of terminal and

lateral moraines occur sporadically in small areas

throughout the areas above 3,500 feet in elevation in

the Klamath Mountains (Busby and Bestland 1992,

Jones and Ferrero 1988, Jones and Ferrero 1989).

On stable slopes of the Dothan/Otter Point

Formation in the udic moisture regime, soils such as

those of the Pyrady series (Typic Palehumults) have

formed in material derived from mudstone and those

of the Zalea series (Typic Haplohumults) have formed

in material weathered from siltstone. Typic

Dystrochrepts such as Yorel soils have formed on

metastable slopes. Skeletal soils such as those of the

Bobsgarden and Tincup series (Umbric Dystrochrepts)

and the Rilea series (Typic Dystrochrepts) have

formed on active slopes. Loamy texture and brown

color are characteristics of these soils. On north-facing

slopes where accumulation of organic matter into the

surface layer occurs more readily, soils such as those

of the Stackyards series (Typic Haplumbrepts) and the

Tolfork series (Pachic Haplumbrepts) have developed

an umbric epipedon. On the Colebrooke Schist

Formation, skeletal soils such as those of the

Saddlepeak and Threetrees series (Typic

Dystrochrepts) and the Scalerock series (Lithic

Dystrochrepts) have formed on stable to active slopes.

On ultramafic rock, the soils typically are loamy, have

an ochric epipedon and a cambic horizon, and are

skeletal. They are on stable to active landscapes.

Examples are the Flycatcher soils (Lithic

Eutrochrepts) and the Cedarcamp and Snowcamp

soils (Dystric Eutrochrepts). The surface layer in the

soils that formed in ultramafic rock typically is red in

color; however, the subsoil and substratum may range

from red to brown to gray, depending on how the rock

weathered into soil material. Soil reaction (pH) of the

ultramafic soils typically is slightly acid or neutral.

These soils have a serpentinitic mineralogy

classification because of the nature of the parent

material.

On stable to active slopes of the Dothan/Otter Point

Formation in the xeric moisture regime, skeletal soils

such as those of the Bearcamp and Brandypeak

series (Typic Xerumbrepts) and the Althouse and

Jayar series (Dystric Xerochrepts) have formed in

material derived from metasedimentary rock. The

Bearcamp and Brandypeak soils are on ridgetops and

north aspects. The Althouse and Jayar soils are on

ridgetops and south aspects. Skeletal soils such as

those of the Skymor series (Dystric Lithic

Xerochrepts) have formed on active, south-facing

slopes. Soils such as those of the Woodseye series

(Lithic Xerumbrepts) are on north-facing slopes where

accumulation of organic matter into the surface layer

occurs more readily. In diorite and related rock on

stable or metastable slopes, soils such as those of the

Rogue series (Dystric Xerochrepts) have formed in

medium textured to coarse textured residual material.

In areas of ultramafic rock, the soils typically are

clayey, have an ochric epipedon, have relatively few

rock fragments, have an argillic horizon, and are red in

color. They are on stable to active slopes. Perdin soils

(Ultic Haploxeralfs) are an example. The surface layer

of the soils that formed in ultramafic rock typically is

red in color; however, the subsoil and substratum may

range from red to brown to gray, depending on how the

original material in this rock weathered into soil

material. Soil reaction (pH) of the ultramafic soils

typically is slightly acid or neutral. These soils have a

serpentinitic mineralogy classification because of the

nature of the parent material.

are needed on all tilled soils. Soil-improving

practices in a conservation cropping system

include the use of rotations that contain grasses

and legumes and the return of crop residue to the

soil. Other practices include the use of green

manure crops of grasses and legumes, proper

dominantly a single soil and similar soils or a

single miscellaneous area.

classification is based. The thickness varies

among different kinds of soil, but for many it is that

part of the soil profile between depths of 10 inches

and 40 or 80 inches.

of North America, between the Central Plains and

the Pacific Ocean.

Corrosion. Soil-induced electrochemical or chemical

improve and protect the soil between periods of

regular crop production, or a crop grown between

trees and vines in orchards and vineyards.

Cropping system. Growing crops according to a

planned system of rotation and management

practices.

Crop residue management. Returning crop residue

control erosion.

Cross-slope farming. Deliberately conducting

farming operations on sloping farmland in such a

way that tillage is across the general slope.

Crown. The upper part of a tree or shrub, including

the living branches and their foliage.

Culmination of the mean annual increment (CMAI).

The average annual increase per acre in the

volume of a stand. Computed by dividing the total

increases in age, the mean annual increment

continues to increase until mortality begins to

reduce the rate of increase. The point where the

stand reaches its maximum annual rate of growth

is called the culmination of the mean annual

increment.

Ground water. Water filling all the unblocked pores of

the material below the water table.

Gully. A miniature valley with steep sides cut by

running water and through which water ordinarily

runs only after rainfall. The distinction between a

subdivisions of the major horizons. An explanation

of the subdivisions is given in the “Soil Survey

Manual.” The major horizons of mineral soil are as

follows:

O horizon.—An organic layer of fresh and

decaying plant residue.

A horizon.—The mineral horizon at or near the

surface in which an accumulation of humified

organic matter is mixed with the mineral material.

Also, a plowed surface horizon, most of which was

originally part of a B horizon.

E horizon.—The mineral horizon in which the main

feature is loss of silicate clay, iron, aluminum, or

some combination of these.

B horizon.—The mineral horizon below an A

horizon. The B horizon is in part a layer of

transition from the overlying A to the underlying

C horizon. The B horizon also has distinctive

characteristics, such as (1) accumulation of clay,

sesquioxides, humus, or a combination of these;

(2) prismatic or blocky structure; (3) redder or

browner colors than those in the A horizon; or (4)

a combination of these.

C horizon.—The mineral horizon or layer,

excluding indurated bedrock, that is little affected

by soil-forming processes and does not have the

properties typical of the overlying soil material.

The material of a C horizon may be either like or

unlike that in which the solum formed. If the

material is known to differ from that in the solum,

an Arabic numeral, commonly a 2, precedes the

letter C.

Cr horizon.—Soft, consolidated bedrock beneath

the soil.

R layer.—Consolidated bedrock beneath the soil.

The bedrock commonly underlies a C horizon, but

it can be directly below an A or a B horizon.

Humus. The well decomposed, more or less stable

part of the organic matter in mineral soils.

Hydrologic soil groups. Refers to soils grouped

according to their runoff potential. The soil

properties that influence this potential are those

that affect the minimum rate of water infiltration

on a bare soil during periods after prolonged

wetting when the soil is not frozen. These

properties are depth to a seasonal high water

table, the infiltration rate and permeability after

prolonged wetting, and depth to a very slowly

permeable layer. The slope and the kind of plant

cover are not considered but are separate factors

in predicting runoff.

Igneous rock. Rock formed by solidification from a

molten or partially molten state. Major varieties

include plutonic and volcanic rock. Examples are

andesite, basalt, and granite.

Illuviation. The movement of soil material from one

horizon to another in the soil profile. Generally,

material is removed from an upper horizon and

deposited in a lower horizon.

Impervious soil. A soil through which water, air, or

roots penetrate slowly or not at all. No soil is

absolutely impervious to air and water all the time.

Indurated. Pertaining to continuous or nearly
Curry County, Oregon 515

continuous cementation by a dominant or

codominant cementing agent.

Infiltration. The downward entry of water into the

immediate surface of soil or other material, as

contrasted with percolation, which is movement of

water through soil layers or material.

Infiltration capacity. The maximum rate at which

water can infiltrate into a soil under a given set of

conditions.

Infiltration rate. The rate at which water penetrates

the surface of the soil at any given instant,

usually expressed in inches per hour. The rate

can be limited by the infiltration capacity of the

soil or the rate at which water is applied at the

surface.

Intake rate. The average rate of water entering the

soil under irrigation. Most soils have a fast initial

rate; the rate decreases with application time.

Therefore, intake rate for design purposes is not a

constant but is a variable depending on the net

irrigation application. The rate of water intake, in

inches per hour, is expressed as follows:

Less than 0.2 ............................................... very low

0.2 to 0.4 .............................................................. low

0.4 to 0.75 ......................................... moderately low

0.75 to 1.25 ................................................ moderate

1.25 to 1.75 ..................................... moderately high

1.75 to 2.5 .......................................................... high

More than 2.5 ............................................. very high

that flows for prolonged periods only when it

receives ground-water discharge or long,

continued contributions from melting snow or

other surface and shallow subsurface sources.

content of iron and manganese oxide because of

chemical reduction and removal, but having a clay

content similar to that of the adjacent matrix. A

type of redoximorphic depletion.

Irrigation. Application of water to soils to assist in

production of crops. Methods of irrigation are:

Drip (or trickle).—Water is applied slowly and under

low pressure to the surface of the soil or into the

soil through such applicators as emitters, porous

tubing, or perforated pipe.

Furrow.—Water is applied in small ditches made by

cultivation implements. Furrows are used for tree

and row crops.

Sprinkler.—Water is sprayed over the soil surface

through pipes or nozzles from a pressure system.

Subirrigation.—Water is applied in open ditches or tile

lines until the water table is raised enough to wet

the soil.

Lacustrine deposit. Material deposited in lake water

and exposed when the water level is lowered or

the elevation of the land is raised.

soil and loose rock, generally when wet or

saturated. The speed and distance of movement,

when one or more of their characteristics are

slightly outside the range defined for the family of

the series for which the soils are named.

Tectonic processes. Pertaining to rock deformation,

including folding, faulting, and uplifting, that has

taken place in the earth’s crust.

Terminal moraine. A belt of thick glacial drift that

generally marks the termination of important

glacial advances.

Terrace. An embankment, or ridge, constructed

across sloping soils on the contour or at a slight

angle to the contour. The terrace intercepts

surface runoff so that water soaks into the soil or

flows slowly to a prepared outlet. A terrace in a

field generally is built so that the field can be

farmed. A terrace intended mainly for drainage

has a deep channel that is maintained in

permanent sod.

Terrace (geologic). An old alluvial plain, ordinarily flat

or undulating, bordering a river, a lake, or the sea.

Texture, soil. The relative proportions of sand, silt,

and clay particles in a mass of soil. The basic

textural classes, in order of increasing proportion

of fine particles, are sand, loamy sand, sandy

loam, loam, silt loam, silt, sandy clay loam, clay

loam, silty clay loam, sandy clay, silty clay, and

clay. The sand, loamy sand, and sandy loam

classes may be further divided by specifying

“coarse,” “fine,” or “very fine.”

Thin layer (in tables). Otherwise suitable soil material

that is too thin for the specified use.

Thrust fault. A reverse fault in which the dip of the

fault plane is at a low angle to horizontal.

Tidal flat. An extensive, nearly horizontal, marshy or

barren tract of land that is alternately covered and

uncovered by the tide. It consists of

unconsolidated sediment that is mostly clay, silt,

and sand.

Tilth, soil. The physical condition of the soil as related

to tillage, seedbed preparation, seedling

emergence, and root penetration.

Toe slope. The outermost inclined surface at the base

of a hill; part of a foot slope.

Topsoil. The upper part of the soil, which is the most

favorable material for plant growth. It is ordinarily

rich in organic matter and is used to topdress

roadbanks, lawns, and land affected by mining.

Toxicity (in tables). Excessive amount of toxic

substances, such as sodium or sulfur, that

severely hinder establishment of vegetation or

severely restrict plant growth.

Trace elements. Chemical elements, for example,

zinc, cobalt, manganese, copper, and iron, in soils

in extremely small amounts. They are essential to

plant growth.

Tuff. A compacted deposit that is 50 percent or more

volcanic ash and dust.

Ultramafic rock. Rock that has a relatively high

content of iron, is less than 45 percent silica, and

has virtually no quartz or feldspar. It includes

peridotite and serpentinite.

Unstable fill (in tables). Risk of caving or sloughing on

banks of fill material.

Upland. Land at a higher elevation, in general, than

the alluvial plain or stream terrace; land above the

lowlands along streams.

Valley fill. In glaciated regions, material deposited in

stream valleys by glacial meltwater. In

nonglaciated regions, alluvium deposited by

heavily loaded streams.

Variegation. Refers to patterns of contrasting colors

assumed to be inherited from the parent material

rather than to be the result of poor drainage.

Vegetative site. A distinctive area that produces a

characteristic natural plant community that differs

from natural plant communities in other areas in

kind, amount, and proportion of forage plants.

Vertical structure. The configuration of elements,

parts, or constituents of a habitat, plant or animal

community, or forest stand in a vertical

orientation.

Water bars. Smooth, shallow ditches or depressional

areas that are excavated at an angle across a

sloping road. They are used to reduce the

downward velocity of water and divert it off and

away from the road surface. Water bars can easily

be driven over if constructed properly.

Wave-cut platform. A gently sloping surface
522

produced by wave erosion that extends into the

sea or lake from the base of the wave-cut cliff. It

includes both the wave-cut bench and the

abrasion platform.

Weathering. All physical and chemical changes

produced in rocks or other deposits at or near the

earth’s surface by atmospheric agents. These

changes result in disintegration and

decomposition of the material.

Well graded. Refers to soil material consisting of

coarse grained particles that are well distributed

over a wide range in size or diameter. Such soil

normally can be easily increased in density and

bearing properties by compaction. Contrasts with

poorly graded soil.

Wilting point (or permanent wilting point). The

moisture content of soil, on an ovendry basis, at

which a plant (specifically a sunflower) wilts so

much that it does not recover when placed in a

humid, dark chamber.

Windblast. The destructive effect of air friction on the

tops of trees in coastal forest stands. Windblast

results in stunted growth and reduces the quality

of the timber and the potential yields.

Windthrow. The uprooting and tipping over of trees by

the wind.

Tables

The tables in this survey give the properties and interpretations for the major

components, which are given in the detailed soil map unit names. The properties and

interpretations for the minor components, which are listed in the detailed soil map units,

will be available in the National Soil Information System (NASIS) database for the

survey area when the data fields for this information are populated.

 *A growing degree day is a unit of heat available for plant growth. It can be calculated by adding

the maximum and minimum daily temperatures, dividing the sum by 2, and subtracting the temperature

below which growth is minimal for the principal crops in the area (Threshold: 40 degrees F).
