MINERAL RESOURCE EVALUATION OF THE U.S. FOREST

SERVICE SIERRA DEMONSTRATION PROJECT AREA,

SIERRA NATIONAL FOREST, CALIFORNIA

By J. P. LOCKWOOD, P. C. BATEMAN, and J. S. SULLIVAN

ABSTRACT

The known geologic history of the 240,000-acre Sierra Demonstration Project area covers about half a billion years and records a complex sequence of sedimentary deposition, volcanism, 

metamorphism, granitic intrusion, erosion, and glaciation. Metal 

deposits of the project area are of three kinds: contact metasomatic deposits formed within the bodies of metamorphic rock 

by reaction with fluids associated with invading magmas, vein 

deposits formed along regionally widespread joints that cut the 

metamorphic and granitic bedrocks, and placer deposits found 

along streams or the courses of former streams. To evaluate the 

mineral potential of each of these types of deposits, we visited 

and sampled all known mines and prospects and conducted a 

detailed geochemical sampling program over the entire area 

to determine the distribution of metals and to locate any anomalous metal concentrations. Samples of 599 stream sediments 

and of 159 bedrock and miscellaneous materials were collected 

and analyzed for 30 metallic elements.

No large mineral deposits suitable for major commercial exploitation are now known or are likely to be found in the foreseeable future in the Sierra Demonstration Project area. Small 

tungsten deposits on Kaiser Ridge have been mined and are 

being further explored. Small low-grade deposits of placer gold 

along Kaiser Creek are being worked sporadically. Very small 

deposits containing high concentrations of copper, lead, molybdenum, silver, and zinc occur along a mineralized joint system 

in the northeast corner of the Sierra Demonstration Project 

area, but their restricted extent and difficult access make exploitation economically unattractive at the present time. Nonmetallic mineral resources of the project area include quartz, 

ornamental stone, and sand and gravel. Because similar products are available much closer to market areas, these resources 

are not likely to be exploited.

Several geologic features are of recreational and educational 

value and can be considered resources for people today and for 

future generations. These include volcanic flows and ash falls, 

hot-spring deposits, glacial moraines, and other features.

INTRODUCTION 

PURPOSE OF THE INVESTIGATION

The public lands of the United States contain the 

nation's principal recreational and wildlife areas and 

important reserves of timber, water, forage, minerals, 

and other natural resources. Public need for all these

resources places different and frequently conflicting demands upon the public lands.

The U.S. Forest Service is deeply concerned that the! 

National Forests be utilized to their fullest extent under 

the multiple-use concept. Accordingly, it established the 

Sierra Demonstration Project to develop rapid and 

accurate means for obtaining thei basic resource information required for intelligent management decisions. 

This project is designed to explore the feasibility of 

obtaining all required resource information concurrently, using up-to-date technological methods from several engineering and scientific disciplines (Swinnerton, 1969).

To evaluate the mineral potential of the Sierra Demonstration Project area, the U.S. Foreist Service asked 

the U.S. Geological Survey early in 1969 to conduct a 

mineral survey of the area. A cooperative program between the two agencies was initiated, and a field survey 

was undertaken during the summer of 1969. In addition 

to the Sierra Demonstration Project area proper, the 

survey covered a wedge of land to the west between the 

project area and the San Joaquin River. Henceforth, 

this expanded area will be referred to as the project 

area. The results of our survey of that area are contained herein.

LOCATION AND GENERAL FEATURES

The Sierra Demonstration Project area is 60 miles 

northeast of Fresno, Calif., about midway between 

Yosemite and Kings Canyon National Parks on the 

gentle west slope of the central Sierra Nevada (fig. 1). 

It includes the Kaiser Peak 15-minute quadrangle and 

the west half of the Mount Abbot 15-minute quadrangle 

(figs. 1,2). Most of the project area is in Fresno County, 

but the northwest comeir extends into Madera County. 

The area is in the north half of the Sierra National 

Forest, and the east one-third lies within the John Muir 

Wilderness. The total area, which includes the area 

between the Avest side of the project areta proper and the

INTRODUCTION

San Joaquin River, encompasses approximately 405 

square miles (1,025 km2 ).

All the project area lies within the drainage basin of 

the San Joaquin River, the South Fork of which flows 

northwestward through the central part of the area. 

Mono Creek and Bear Crefek are principal tributaries to 

the South Fork within the project area. Along the north 

edge of the area, north-flowing Silver and Fish Creeks 

drain basins on either side of Silver Divide. In the 

southwestern part of the area, Kaiser Creek drains the 

north flank of Kaiser Ridge, and Big Creek drains the 

south flank.

At higher elevations many small natural lakes fill 

depressions ci-eated by glacial erosion during Pleistocene alpine glaciation, but the four largest lakes in the 

area (frontispiece) are manmade reservoirs for hydroelectric power projects. Most elevations within the project area are 6,500 to 9,500 feet above mean sea level, 

although elevations rise to 12,349 feet at Mount Hooper, 

4 miles northeast of Florence Lake, and drop to 2,450 

feet where the San Joaquin River flows out of the area 

at the southwest corner. The upper part of the South 

Fork of the San Joaquin River flows in a broad glacially 

modified valley, but downstream the river is entrenched 

in a narrow canyon 1,600 feet deep.

Precipitation ranging from 24 to 32 inches per year 

is primarily snow at higher elevations and rain at lower 

elevations (U.S. Weather Bureau, 1959). Forests of 

ponderosa, Jeffrey, and lodgepole pine along with red 

and white fir cover most of the area. Logging is currently being carried on in the Kaiser Creek basin. At 

lower elevations shrubs such as manzanita. Sierra chinquapin, and mountain white-thorn are common. Willows, quaking aspen, and alder line many streams. At 

highest elevations glacial erosion has exposed large 

areas of bedrock, and the sparse soil-covered areas support only alpine vegetation.

State Highway 168 from Fresno ends at Huntington 

Lake, near the south boundary of the project area (fig. 

2). Continuing on from the northeast corner of Huntington Lake into the project area is a narrower one- to 

two-lane blacktop road which leads over Kaiser Ridge 

through 9,175-foot-high Kaiser Pass into the basin of 

the South Fork of the San Joaquin. One branch of this 

road ends at Lake Edison and the other at Florence 

Lake. By late 1971, this road had been widened and 

improved nearly to Kaiser Pass. Beyond Kaiser Pass 

the road is narrow and steep, which tends to limit the 

number of people entering the area. On the other hand, 

it is adequate for passenger car traffic and offers a highly 

scenic drive into this undeveloped country in the heart 

of the Sierra Xevada.

The other route into the area is an unpaved, graded 

road that begins near the town of Big Creek southwest 

of Huntington Lake and extends northward along the 

east valley wall of the San Joaquin River into the 

Kaiser Creek basin. This road provides access to recreational areas along the San Joaquin River and Kaiser 

Creek and is also used by logging trucks. Branching 

from these two roads are a few unimproved roads suitable mainly for 4-wheel-drive vehicles. All roads into 

the area are closed by snow during the winter months.

A network of trails for hikers and horseback riders 

crosses the area. The John Muir Trail crosses the east 

edge of the area close to the crest of the Sierra Nevada.

GEOCHEMICAL INVESTIGATION

A program of geochemical sampling was carried out 

to gain information that might bear on the origin of 

the known mineral deposits and to evaluate the potential of the project area for undiscovered mineral resources. This program involved extensive collection of 

both bedrock and stream-sediment samples and laboratory analysis to determine metal content.

SAMPLING PROGRAM

Before any samples were collected, a sampling pattern was laid out for both stream sediments and bedrock. Initially, we planned to collect about one 

stream-sediment sample per square mile, and about one 

bedrock sample per 8-square-mile area, but early 

analytic results indicated the need for more samples of 

both kinds. We collected 599 stream-sediment samples 

and 108 samples of typical bedrocks, the latter including 84 granitic rocks, 14 mctamorphic rocks, and 10 

volcanic flows. In addition, we collected 50 other samples, including nine from lode deposits that have been 

worked, 23 from unexplored quartz veins, six of altered 

bedrock, six of mineral-spring precipitates, and six of 

miscellaneous materials.

The samples of typical bedrock were taken primarily 

to establish regional patterns of metal content that 

might affect the compositions of the stream sediments. 

Stream-sediment samples reflect the metal content of 

watershed areas rather than local rock units; so many 

samples were collected just above stream junctions in 

order to evaluate the metal content of individual drainage basins.

Early analyses indicated that stream sediment is not 

chemically homogeneous at any one place. Metals such 

as gold, tungsten, iron, chrome, and vanadium are preferentially concentrated in the coarse gravel and boulder-rich parts of the streambed, whereas copper and 

molybdenum are most highly concentrated in fine sand 

and mud. To obtain comparable samples at each locality,

459-605 O - 72 -2
SIERRA DEMONSTRATION PROJECT AREA

approximately one-half the required amount of sieved 

sand ordinarily was taken from gravel near the bottoms 

of streams, and one-half was taken from sandbars or 

mud along stream margins. For large streams, however, 

it was not always possible to sample bottom gravels 

owing to high water. This was especially difficult early 

in the summer, when melt runoff from a record snowpack (U.S. Weather Bureau, 1969, p. 78, 116) caused 

very high water levels.

Most sand samples were wet sieved at the collecting 

site with a small set of aluminum sieves consisting of a 

20-mesh sieve at the top, an 80-mesh sieve, and a collection cup at the bottom. Some samples were collected in 

bulk, dried, and sieved several days after being collected. 

Samples of 10 to 30 grams each were taken from each 

of the two size fractions and placed in cloth sample bags. 

Initial chemical analyses of both size fractions indicated 

that the 80 mesh fraction almost invariably contained 

higher metal concentrations than the 20, + 80 fraction 

and was thus more sensitive as an indicator of metal 

anomalies. For this reason only the 80 fraction was 

ordinarily submitted for analysis. Some 20, +80 fractions were submitted as checks for analytical error. In 

table 3, the size fraction analyzed is indicated by a 

numerical suffix. Thus, sample 005-20 is the 20, +80 

fraction, and 005-80 is the 80 fraction.

ANALYTICAL METHODS AND PROCEDURES

Most of the samples were analyzed chemically and 

spectrographically for a total of 30 different metallic 

elements (table 1-3), although 52 of the bedrock samples 

were only analyzed spectrographically. The chemical 

analyses, more sensitive and precise than spectrographic 

analyses, were made for gold, copper, tungsten, and 

arsenic. The first three elements were considered important potential resources in the project area, and arsenic was considered important as a possible indicator 

of mineralization in general. Semiquantitative spectrographic analyses were made for 30 elements: silver, arsenic, gold, boron, barium, beryllium, bismuth, calcium, 

cadmium, cobalt, chromium, copper, iron, lanthanum, 

magnesium, manganese, molybdenum, niobium, nickel, 

lead, antimony, scandium, tin, strontium, titanium, 

vanadium, tungsten, yttrium, zinc, and zirconium. Spectrographic analyses of arsenic, gold, copper, and tungsten are omitted from table 3 because these elements 

were also analyzed chemically, and calcium, magnesium, 

and titanium are omitted because they are not significant 

in this study. Cadmium and antimony are omitted from 

table 3 because they were not found in any sample.

Approximate mean metal contents were calculated 

for each group of principal sample types analyzed (table 3). Mean values in parentheses are considered unreliable, generally because measureable values are too 

few for calculation of a representative average.

All analyses were performed by Geological Survey 

personnel. Chemical analyses were made in Winnemucca, Nev., Denver, Colo., and in a mobile field laboratory based at the High Sierra Ranger Station. All spectrographic analyses were performed in Denver, except 

for sample 105F and 51 other bedrock samples (with 

numbers beginning with "A" or "KP"), which were 

analyzed in Menlo Park, Calif. Samples received by the 

analytical laboratories were ground if necessary (for 

example, rock samples) and sieved to 80 mesh size. 

The following quantities of sample were then removed 

for analysis:

The aliquots for gold and copper were dissolved in 

acid and analyzed by standard atomic absorption techniques (Ward and others, 1969). Lower sensitivities of 

0.02 and 10 ppm (parts per million), respectively, were 

obtained by this method. Tungsten and arsenic contents 

were determined by colorimetric analysis, as described 

by Ward, Lakin, Canney, and others (1963, p. 40-14 and 

78-79). Minimum sensitivities of these methods are 20 

and 10 ppm, respectively. The methods of spectrographic analysis are described by Ward, Lakin, Canney, 

and others (1963, p. 91-94).

PREVIOUS STUDIES

Geologic study of three quadrangles that cover the 

project area was nearly completed when this study was 

begun and provided a sound basis for evaluating the 

mineral potential of the area. Geologic maps of the 

Shuteye Peak quadrangle (Huber, 1968) and the Kaiser 

Peak quadrangle (Bateman and others, 1971) are 

already published, and a geologic map of the Mount 

Abbot quadrangle is in final stages of preparation.

The first geologic observations of the area were made 

by members of J. D. Whitney's geological survey party, 

who traversed the project area in 1864 (Whitney, 1865). 

A reconnaissance study of the geomorphology and 

glacial geology of the area was made by F. E. Matthes 

in the 193(Vs and published in I960. A more detailed 

study of the glacial geology along Mono Creek and the 

South Fork of the San Joaquin River was made by 

Birman (1964) at the time of construction of Vermillion 

Dam (below Lake Thomas A. Edison). Chesterman 

(1942) described a small area of metamorphic rocks 

north of Kaiser Peak, and Hamilton (1956) studied the 

geology of a part of the Demonstration Project area
GEOLOGIC FEATURES

immediately north of Huntington Lake. The geology of 

the north half of the Mount Abbot quandrangle, including the northeast corner of the Demonstration Project 

area, has been described by Sherlock and Hamilton 

(1958).

No comprehensive mineral resource surveys had been 

conducted in the area of the Sierra Demonstration Project prior to this study, although the area has been extensively prospected over the past century, mainly for 

gold and tungsten.

ACKNOWLEDGMENTS

The U.S. Forest Service provided excellent support 

during the field investigations. Leigh B. Lint of the 

Forest Service's Engineering Division was the principal 

liaison officer between the Geological Survey and the 

Forest Service and was responsible for coordinating 

helicopter support and providing aerial photographs. 

The Forest Service provided 48.1 hours of helicopter 

flight time in support of our study; the capable helicopter pilotage of Harold Dickey contributed to our 

success in covering a large area in a very short period. 

The many courtesies extended by Mr. Lint and by Arnold P. Snyder and Michael P. Goggin of the High 

Sierra Ranger Station are greatly appreciated. Color 

aerial photographs of the project area at scales of 

1:48,000 and 1:24,000 taken during the summer of 1968 

for the Forest Service, greatly facilitated our field investigations. They were invaluable in locating areas of 

mineralized or otherwise anomalous rock formations, 

enabled us to plan helicopter landing sites, and greatly 

facilitated cross-country foot traverses over difficult 

terrain.

Frank E. Barr assisted field operations for 1 month 

under the sponsorship of the National Science Foundation Research Observer Program for secondary school 

instructors. Ronald J. Fitzliugh assisted in the sampling 

program and is largely responsible for compilation of 

the extensive geochemical data. Messrs. Floyd T. Wilmoth and Lawrence C. Wehmeyer kindly showed us 

their mining claims and allowed us to sample their 

workings.

GEOLOGIC FEATURES

The Sierra Demonstration Project area is near the 

center of the Sierra Nevada batholith, a large composite 

body of granitic rock that makes up about 80 percent 

of the bedrock of the Sierra Nevada. Metamorphic rocks 

older than the batholith underlie the remainder of the 

Sierra Nevada. The geology of the Sierra Nevada and 

the Sierra Nevada batholith was described by Bateman 

and Wahrhaftig (1966) and by Bateman and Eaton 

(1967). Readers desiring more-detailed information

will find numerous references to technical studies in 

these publications.

Rocks of the project area can be broadly divided into 

four principal groups: (1) old, pregranitic metamorphic rocks, (2) granitic rocks, (3) much younger volcanic formations, and (4) very young unconsolidated 

sedimentary deposits that overlie bedrock and include 

both stream and glacial deposits. The distribution of the 

major bedrock units is shown in figures 9-14.

METAMORPHIC ROCKS

The pregranitic rocks include all the sedimentary 

and volcanic rocks into which the granitic magmas were 

intruded. These rocks were metamorphosed by heat and 

pressure, which preceded and accompanied the emplacement of granitic magma. All these metasedimentary 

rocks and most of the metavolcanic rocks are conspicuously stratified, and although they were deposited originally in horizontal or gently dipping layers, they have 

been strongly folded and faulted and in most exposures 

dip steeply or are vertical. The metamorphic rocks must 

have been more widespread before the extensive erosion 

that followed emplacement of the granitic rocks. 

Although not very abundant in the project area, the 

metamorphic rocks are favorable hosts for metallic 

ore deposits and are of particular importance in this 

investigation.

The metamorphic rocks include an older group of 

metasedimentary rocks and a younger group of metavolcanic rocks. The metasedimentary rocks were derived 

by the erosion of an ancient landmass and were deposited in Paleozoic seas 575-235 m.y. (million years) 

ago, when shallow seas covered much of western North 

America. These strata were folded, faulted, and eroded 

before the overlying meta volcanic rocks were deposited. 

Remnants of metasedimentary rocks include numerous 

masses along Kaiser Ridge and the eastern part of the 

Mount Morrison roof pendant, which extends into the 

northeast corner of the project area. The principal rocks 

along Kaiser Ridge are quartzite, hornf els, and marble. 

The most common rock in the part of the Mount Morrison roof pendant within the project area is ihornfels.

The metavolcanic rocks were deposited across the 

metasedimentary strata after these strata had been deformed and then truncated by erosion, during the early 

and middle Mesozoic, 235-135 m.y. ago. They include 

metamorphosed lava flows, pyroclastic deposits, associated dikes and sills, and sedimentary rocks that were 

derived from the volcanic rocks by rapid erosion shortly 

after deposition. Remnants of metavolcanic rocks occur 

north of Silver Divide, northeast of Lake Edison, northeast of Florence Lake, and in the western part of the 

Mount Morrison roof pendant. The most common meta-
6 SIERRA DEMONSTRATION PROJECT AREA

volcanic rocks are light- to dark-gray mica schists, some 

of which stain orange on weathering. They were formed 

by the recrystalization of volcanic ash beds and associated lava flows. Typical metavolcanic rocks are exposed along the Bear Creek trail at and above Beiar 

Diversion Dam. Dark metavolcanic schists that form 

the top of Red and White Mountain in the Mount Morrison roof pendant can be viewed from near the High 

Sierra Ranger Station.

GRANITIC ROCKS

The granitic rocks underlie about 95 percent of the 

project area. Thov intruded the oldeir, folded and 

faulted sedimentary and volcanic rocks as molten or 

partly molten magma. The granitic rocks of the project 

area consist of at least 20 different plutons, most of 

which were intruded and solidified at different timels. 

For this report, the plutons have been grouped into 

seven map units (figs. 9-14). These plutons are divisible 

into two principal age groups: a younger group that 

was emplaced 90-79 m.y. ago and an older group that 

was emplaced more than 100 m.y. ago (Evernden and 

Kistler, 1970).

The plutons of the older group includes three geographically separated units: (1) the/ granodiorite of 

Dinkey Creek in the southwestern part of the project 

area, (2) a pluton of quartz monzonite northeast of 

Florence Lake, and (3) the alaskite of Graveyard Peak 

north of Lake Edison. The relative ages of these plu'tons 

are not known, since the plutons are nowhere in contact 

with one another.

The largest of these older plutons is the granodiorite 

of Dinkey Creek. Rocks of this pluton are light to medium gray and nearly everywhere contain abundant dark 

inclusions of biotite and hornblende diorite. In most 

places the granodiorite of Dinkey Creek is separated 

from the Mount Given Granodiorite, which belongs to 

the younger group, by the metasedimentary rocks of 

Kaiser Ridge. Radiometric age dates from the granodiorite of Dinkey Creek range from 115 to 104 m.y. 

(Evernden and Kistler, 1970). A few older, small plutons of granodiorite.aiufc quarts? monzonite along the 

west margin of the project area are included with the 

granodiorite of Dinkey Creek in figures 9-14.

The quartz monzonite of Bear Dome northeast of 

Florence Lake is generally fine grained and forms prominent topographic features such as Bear Dome, Jackass Dike, and The Tombstone. Much of this pluton is 

rimmed by the light-colored metavolcanic rocks of Bear 

Creek.

The alaskite of Graveyard Peak is a large mass of 

very light colored granite along the north margin of 

the project area. This rock, which commonly weathers

to red orange, forms the Vermillion Cliffs northeast of 

Lake Edison. Also included as alaskite in figures 9-14 

are numerous small bodies of other old rocks that range 

in composition from gabbro to granodiorite.

Age relations among the younger (90-79 m.y.) group 

are well known. The oldest pluton of this group is the 

Lamarck Granodiorite, a narrow body whidh crops out 

northeast of the Bear Creek metavolcanic rocks. This 

granodiorite, widespread south of the project area, is 

medium grained, contains abundant dark inclusions, 

and is typified by large well-formed crystals of black 

hornblende. In the southeast corner of figures 9-14, a 

body of porphyritic quartz monzonite similar to the 

quartz monzonite of Recess Peak has been included with 

the Lamarck Granodiorite.

Next oldest is the Mount Givens Granodiorite, which 

underlies the entire basin of the San Joaquin River 

between Kaiser Ridge and Lake Edison. The Mount 

Givens Granodiorite is one of the largest single plutons 

in the Sierra Nevada batholith and extends several miles 

to the north, south, and west of the project area. This 

granodiorite is exposed in nearly all the readouts from 

Kaiser Pass to Florence and Edison Lakes. Textural'ly 

the Mount Givens is a variable rock, although in most 

places it is light gray and medium grained equigranular 

and contains scattered dark discoidal inclusions. Along 

much of the west margin of the project area, i/^-1-indhsize phenocrysts of potassium feldspar are abundant, 

and dark inclusions are absent.

Next oldest of the 90-79 m.y. group is the granodiorite of Lake Edison. This pluton trends northwestsoutheast across the northeastern part of the project 

area and forms the east shores of Lake Edison. It is 

generally fine grained and is characterized by abundant 

small crystals of honey-colored sphene. Along its margins much of this pluton is light colored and has the 

composition of quartz monzonite.

The youngest pluton of this group is the quartz monzonite of Recess Peak, in the northeast corner of the 

project area. This unit is the coarsest grained of all 

granitic rocks in the project area and typically contains 5-20 percent of giant pihenocrysts of potassium 

feldspar, which are as much as 4 inches long. Although 

all in situ exposures of this quartz monzonite are far 

from roads, large boulders of this rock are common in 

glacial moraines near Lake Edison.

VOLCANIC ROCKS

After the granitic rocks cooled and solidified, the 

Sierra Nevada was uplifted in various episodes, and 

several miles of overlying rock was removed by erosion, 

exposing the levels of granitic rocks we see today. About 

10 m.y. ago, volcanic activity resumed in the Sierra
GEOLOGIC FEATURES

Nevada, and it has continued into historical times. In 

the project area, volcanoes along Silver Divide and 

upper Mono Creek erupted about 3i/£ m.y. ago (Dalrymple, 1963) and poured moderately large quantities 

of trachybasalt lava into low-lying areas. Feeder pipes 

for these volcanoes are present east of Pincushion Peak 

and on Volcanic Knob. Erosion has removed the superstructure of the volcanoes as well as most of the lava 

flows which must have once covered much of the San 

Joaquin River's South Fork valley. Remnants of the 

flows crop out along the South Fork valley, Silver 

Divide, and Mono Creek.

JOINTS

Conjugate joints are well developed in the bedrock 

of most parts of the project area and are among the 

most prominent structural features observable in aerial 

photographs of this region (frontispiece, especially 

near Florence Lake). The joints average about N. 40° E. 

and N. 20° W. in strike and dip steeply, but the range 

of attitudes is wide. They were formed several million 

years ago by regional stresses after consolidation of the 

granitic rocks; many are the loci of later small-scale 

strike-slip faults (fig. 3). Longer and more conspicuous 

joints contain crushed and altered rock that erodes to 

form low-lying linear trenches along which soil, brush, 

and timber are concentrated. Shorter and less conspicuous joints are well exposed in nontimbered areas, 

and many contain narrow veinlets of quartz, epidote, 

and chlorite (fig. 4). These veinlets are of potential 

economic importance, since they commonly contain 

minor amounts of ore minerals.

UNCONSOLIDATED DEPOSITS 

GLACIAL DEPOSITS

During the Pleistocene, most of the project area was 

repeatedly covered by thick alpine glaciers. These ice

masses transported enormous quantities of rock downhill and greatly modified the topography of the region. 

Deposits of glacially transported till, moraine, and outwash cover approximately 15 percent of the project 

area, but are not shown in figures 9-14. The engineering 

properties of these glacial deposits are important to 

construction activities, and persons interested in their 

distribution should refer to detailed geologic maps of 

this area (see section on "Previous Studies") and to the 

report of Birman (1964).

LAKE AND STREAM DEPOSITS

Since the last glacial recession, lakes at higher elevations have accumulated only small amounts of silt and 

clay. A few lakes at lower elevations have, however, been 

completely filled with sediment and now are beautiful

8 SIERRA DEMONSTRATION PROJECT AREA

mountain meadows such as Graveyard Meadows north 

of Lake Edison. Most streams have only minor accumulations of gravel and sand, and large alluvial deposits 

have developed only along the San Joaquin River. 

Stream sediments are of economic interest since those 

in the western part of the project area contain placer 

gold.

PUMICE

Violent eruptions in the Mammoth Lakes region several hundred years ago ejected tremendous volumes of 

white rhyolite pumice, which was carried southward by 

winds into the east half of the project area. In the northeastern part of the area, waterlogged pumice makes up 

a large fraction of the stream sediments; however, the 

amount of pumice decreases southward, and at Kaiser 

Pass only scattered fragments are present in sheltered 

pockets in bedrock.

MINERAL RESOURCES 

RELATION OF MINERAL DEPOSITS TO GEOLOGY

Metalliferous deposits of the Sierra Demonstration 

Project area fall into two groups lodes (formed and 

found within the granitic and metamorphic bedrock of 

the area) and placers (heavy minerals transported and 

concentrated by streams).

The lode deposits are of two kinds: contact metasomatic deposits found only in metamorphic rocks and 

vein deposits that occur in both the metamorphic and 

granitic rocks. The contact metasomatic deposits were 

mainly formed by hot, metal-bearing fluids that emanated from cooling granitic magma and reacted with 

and partly replaced metamorphic rocks along or near 

granitic contacts. Such processes formed the tungsten 

deposits of Kaiser Ridge and also may account for anomalies of tungsten, copper, gold, tin, and zinc associated 

with other metamorphic rock masses (table 3). The concentration of some metals may also have been locally 

enhanced by 'hot, circulating fluids, which redistributed 

metals originally present in small amounts throughout 

the metamorphic rocks. Sulfide-bearing quartz veins 

that cut metavolcanic rocks along Bear Creek may have 

such an origin.

The vein deposits postdate the granitic rocks and were 

formed by metal-bearing solutions that migrated upward along a system of regional joints. Many of these 

joints are actually small faults and show small amounts 

of lateral offset (fig. 3). They cut metamorphic and 

granitic bedrock alike. The veins along these joints consist principally of quartz, epidote, and chlorite, and 

commonly contain small grains of pyrite, molybdenite, 

argentiferous galena, and other sulfide minerals. The

veins range in width from less than one-sixteenth inch 

to about 6 feet; most are between one-fourth and 1 inch 

wide. They generally are bordered by alteration zones 

much wider than the veins themselves. These alteration 

zones, in which plagioclase is converted to epidote, albite, and sericite, and mafic minerals to chlorite, are 

more resistant to weathering than the surrounding unaltered granite and typically stand out in relief (fig. 4). 

These mineralized veins are most abundant in the northeast half of the project area.

The placer deposits are related to bedrock geology 

only indirectly they formed downstream from a bedrock source. Local topography is more important than 

bedrock lithology in controlling the distribution of 

placer deposits. All placer deposits in the project area 

are along segments of stream courses or former stream 

courses where the gradient is low; placer concentrations 

are uncommon where the gradient is steep and streamflow rapid.

KNOWN MINERAL OCCURRENCES

TUNGSTEN MINES AND PROSPECTS ALONG 

KAISER RIDGE

Like most of the tungsten deposits in the Sierra 

Nevada, deposits in the project area are all of contactmetasomatic origin (Bateman, 1965, p. 123-150). Such 

deposits form when hot aqueous solutions given off by 

bodies of cooling and crystallizing granitic magma react with marble and other calcareous country rocks. 

Contact metasomatism of this kind produces a dark 

silicate rock, tactite (or skarn), composed chiefly of 

pyroxene of the diopside-hedenbergite series, garnet of 

the grossularite-andradite series, quartz, and epidote, 

Some tactite contains scheelite (CaWO4 ), the only important tungsten-bearing mineral in contact-metasomatic deposits; tactite may also contain metallic sulfides and oxides of potential economic importance. Many 

tungsten ores contain less than 1 percent WO3 , so the 

small amount of scheelite required for commercial exploitation may be visible only under ultraviolet light.

Within the project area scheelite-bearing tactite 

occurs along Kaiser Ridge, where the tactite hosts are 

calcareous rocks in the metamorphic septum that separates the granodiorite of Dinkey Creek 011 the south and 

west from the Mount Givens Graiiodiorite on the north 

and east. Marble and calc-silicate-hornfels are common 

along a 5-mile span that extends from near the center 

of the XEi/4 sec. 34, T. 7 S., R. 26 E. (about 1 mile north 

of the Forest Service campground of Badger Flat) 

northeast to near Pry or Lake (unnamed on the Kaiser 

Peak quadrangle topographic map) in the S^NE1^ 

sec. 13, T. 7 S., R. 26 E. Prospect pits are common 

throughout this span of the septum, especially near
MINERAL RESOURCES

Twin Lakes (Chesterman, 1942), but the only reported 

production has been from the unpatented Lucky Blue 

claims held by Mr. Floyd T. Wilmoth of SunsetWhitney Ranch, Calif. A search of mining records at 

the Fresno County Recorder's Office in April, 1970, revealed no other tungsten claims for which current 

notices of annual assessment work have been filed.

The Lucky Blue claims cover the northwest third of 

the exposures of calcareous rocks (fig. 5). Claims 4 and 

5 can be reached by a private road from the Forest 

Service campground at Sample Meadows, and the other 

claims are readily accessible from this road. Mr. Wilmoth estimates that tungsten ore valued at approximately $50,000 was produced from claims 4 and 5 during and following the Korean War (1951-56). Much 

of this production was from glacial erratics that were 

scattered along the ridge that extends north from the 

location cuts of the two claims. Most of the exposed 

scheelite-bearing boulders have been mined, and we saw 

only one, which appeared under ultraviolet light to contain several percent WO3 . Ore was also shipped from 

the location cuts on these two claims, according to Mr. 

Wilmoth.

The principal metamorphic rocks in the vicinity of 

these opencuts are conspicuously crossbedded white 

quartzite, pelitic hornfels, and oalc-silicate 'hornfels. 

Tactite pods formed principally in limestone or calcareous interbeds within the quartzite. At each opencut the 

tactite is adjacent to dikes and irregular bodies of pegmatite, a relationship suggesting strongly that the tactite is genetically associated with the emplacement of 

the pegmatite magma, which probably was saturated 

with water.

Night inspection by ultraviolet light of claims 3, 4, 

and 5 (which contain the highest grade ore now exposed, according to Mr. Wilmoth) revealed that soheelite is limited to a few small areas several square feet 

in extent within and adjacent to the opencuts. Examination of the metamorphic rocks between the opencuts 

revealed only a few small areas of tactite that contains 

scheelite. Within the mineralized zones scheelite is irregularly distributed in grains that range from pinpoint size to half an inch in diameter. The coarsest 

scheelite is exposed on chain 3. Only pinpoint-size 

grains were found on claim 4, but pyrite, chalcopyrite, 

sphalerite, galena, and magnetite were also present 

there in irregular streaks and masses.

We obtained composite samples from each of the 

three opencuts by chipping across each face at different levels, being careful to obtain an even distribution 

of chips. We took two samples each from claims 4 and 5, 

and one from claim 3. One sample from claim 4 (2532A) 

consists mainly of sulfides, and the other (2532B) is

posed. The samples were analyzed chemically for gold, 

copper, arsenic, and tungsten and spectrographically 

for a wide variety of elements (table 1).

The analyses show that only on claim 3 is tungsten ore 

of commercial grade present at the surface. Claim 4

contains only trace amounts of tungsten but significant 

amounts of copper, lead, and zinc. Nevertheless, the surface extent of the mineralized areas on all three claims 

is too small to permit accurate estimates of inferred ore 

reserves.

PICK AND SHOVEL MINE

The Pick and Shovel mine is within the John Muir 

Wilderness in the northeastern part of the project area 

(fig. 2). The mine property consists of seven unpaterted 

claims east of Minnow Creek in the northwest corner of 

the Mount Abbot quadrangle. The claims, held by G. T. 

Burns, B. Baldwin and L. C. Wehmeyer of Clovis and 

Coalinga, Calif., were filed in 1952 on the site of earlier 

prospect pits.

The principal workings are on a hillside near the center of the area covered by the claims (sample loc. 105 

in fig. 9) and consist of a drift approximately 125 feet 

long, which intersects a vertical shaft approximately 

80 feet deep. These workings follow a quartz vein system that strikes N. 50° E. and dips 80°-85° NW. Where 

the vein system is exposed in faces on the drift, it consists of several narrow i/2~4-inch-wide red-stained 

quartz veins in highly altered granite. The width of this 

veined zone ranges from 3 to 4 feet in the part of the 

mine examined. Chemical analyses of three samples 

from the vein system are given in table 2. Sample 105A

is composed of the typical red-stained quartz and shows 

low values of gold, silver, and lead. Sample 105C is composed of red-stained quartz containing fracture fillings 

of a yellow, powdery mineral tentatively identified by 

Mr. Wehmeyer as carnotite and shows relatively high 

values of lead, vanadium, and zinc. Sample 105F, altered quartz monzonite adjoining the quartz veins, 

shows almost no significant mineralization other than a 

small amount of lead.

Several tons of ore have been mined and stockpiled 

near the portal. This ore consists of mineralized quartz 

containing relatively abundant galena, pyrite, and malachite and lesser amounts of sphalerite, chalcocite, bornite, chalcopyrite, and azurite. Laumontite and stilbite 

are associated gangue minerals in some specimens. A 

grab sample composed of numerous small specimens of 

high-grade ore from the stockpile contains high values 

of copper, lead, and zinc (table 2, sample 105B). An 

analysis of one sample of high-grade copper ore containing visible chalcocite (105D) shows 3.6 percent 

copper, 0.02 percent silver, high content of lead and zinc, 

and minor amounts of cadmium and gold.

According to Mr. Wehmeyer, most of the high-grade 

ore on the stockpile was taken from an inaccessible incline below the present mine level. The ore body apparently was pod shaped. The present mining operation, 

carried on sporadically during the summer, is directed 

toward the discovery of either an extension of this body 

or new bodies.

The mineralizing solutions that formed the Pick and 

Shovel deposit and other veins nearby moved along a 

steeply dipping regional joint system that strikes N. 

35°-55° E. in this area. In many places the quartz veins 

typically found along these joints widen abruptly to 

form small (2-4 in. maximum length) pockets of redstained quartz in which sulfides, especially galena and 

pyrite, are visible. These pockets are irregularly distributed along individual joints and are nowhere very 

abundant. Some of these mineralized pockets appear to 

have formed by replacement of wallrock, but most have 

formed through fillings of voids left by differential lateral movement between the rock on either side of the 

joint (fig. 6). The main ore body at the Pick and Shovel 

mine probably formed by this process, although on a 

larger scale. Other ore pockets similar to the one mined 

probably exist along the Pick and Shovel joint system, 

but they are probably distributed erratically and will be 

expensive to find, develop, and mine.

PLACER GOLD DEPOSITS OF KAISER GREEK

Kaiser Creek, in the southwest quarter of the project 

area, has been the site of sporadic small-scale placer 

mining for about 100 years. Early records are sparse 

but indicate that gold wias discovered along Kaiser 

Creek prior to 1880. The earliest published reference to 

these placers (Burchard, 1882, p. 33) stated,

Rich gravel deposits are reported along the banks of Keyser 

Gulch. The bed of the creek was rich, and was mined out years 

ago, but the banks were never extensively prospected. The 

deposits now being opened are said to indicate an ancient river 

channel, which has not hitherto been discovered in the country.

U.S. Bureau of Land Management survey plats of 

1882-85 show that "old miner's cabins" and "old mining 

ditches" existed at that time. Today, all that remains of 

these old workings are a few gravel piles overgrown 

with yellow pine along lower Kaiser Creek in the 

vicinity of Kaiser Diggings Guard Station.

Small placer operations were conducted along Kaiser 

Creek in the early part of this century (Bradley, 1915, 

p. 444-445), and during the Depression many people 

reportedly subsisted through placer mining from 

Sample Meadow to the San Joaquin River. Records at 

the Fresno County Recorder's Office indicate that the 

only presently active claim in the area (April, 1970) 

is the Rose-Kay claim on lower Kaiser Creek iy2 miles

junction with the San Joaquin River. Sieved stream 

sediments from this part of Kaiser Creek contain as 

much as 13 ppm gold, and panned concentrates show 

as much as 34 ppm. Free gold was observed in about 

half the panned samples but was extremely fine (most 

grains were less than 400 microns in diameter). Panning 

of modern stream sediments indicates little gold is 

presently being moved by Kaiser Creek; however, good 

colors can be panned from beneath large boulders or 

from bedrock crevices under roots. Good colors were 

also panned from colluvium several feet above the 

present stream level. One local resident, whom we observed operating a small sluice box on an unclaimed 

part of middle Kaiser Creek, reported recovering $3-$7 

in gold per day from bedrock crevices high on the banks 

of the creek.

The sparseness of quartz veins near Kaiser Creek and 

the fact that the one local vein analyzed (table 3, sample 

208) contains no gold suggest distant sources for thip 

metal. At Kaiser Diggings the creek occupies a relatively flat catchment basin ideally situated to entrap 

gold carried in from any source. Any gold reaching the 

basin probably remained behind and became concentrated as less dense, more easily disintegrated detritus 

was washed away. The gold appears to have been transported into this basin by a combination of glacial and 

stream transport processes. An observed association of 

gold and tungsten in the stream sediments along Kaiser 

Creek suggests that Kaiser Ridge was once source (figs. 

10, 12), for the tungsten was almost certainly derived 

from there. Floyd T. Wilmoth states that a single 

narrow quartz vein on his Lucky Blue tungsten claims 

north of Kaiser Ridge had a high gold content. Low concentrations of gold (0.02-0.04 ppm) in stream sediments near Kaiser Ridge indicate a weak anomaly along 

most of the ridge but do not suggest that any major 

deposit is currently being eroded. If commercial lode 

deposits were ever present, they have been eroded away, 

and if the placer gold at Kaiser Diggings came from 

Kaiser Ridge, it was probably concentrated from small 

discontinuous lode deposits of no commercial importance, such as may still be present.

Kaiser Ridge was not the only source of placer gold, 

however. Sediment samples collected well north of 

Kaiser Creek (figs. 9, 10, samples 213, 1082, 1083) contain as much as 0.63 ppm gold, and this gold could not 

have been transported by the streams that now drain 

the ridge. Some of this gold could have been carried 

from distant eastern sources by glaciers that once flowed 

down the South Fork of the San Joaquin River. Birman (1964) mapped older glacial deposits along the 

north side of Kaiser Creek; these deposits indicate that 

large amounts of potentially auriferous glacial material
13

derived from the east once covered the Kaiser Creek 

drainage.

Most of the Kaiser Creek gold was apparently mined 

prior to 1880, when records of small producers were 

poorly kept, and almost no production records were 

found for these placers. The only production figures 

found, for 1940, were 7 ounces of gold and 3 ounces of 

silver (U.S. Bureau of Mines, 1933-68). A comparison 

of the Kaiser Creek area with similar placer districts 

of the southern Sierra Nevada indicates total gold production to date from Kaiser Creek of probably 500 

ounces or less, but certainly less than 1,000 ounces 

(M. G. Johnson, oral commun., 1970).

All easily worked gold deposits of economic significance along Kaiser Creek appear to have already been 

evaluated and mined, and it is unlikely that any major 

deposits remain. Small amounts of gold are present, 

however, and small placer operations and recreational 

gold panning will probably be carried on for many years 

to come.

PLACER GOLD DEPOSITS OF MILL CREEK

Mill Creek, near the west margin of the project area 

northwest of Kaiser Creek, has also yielded small 

amounts of gold. Vestiges of a former placer operation 

indicate that mining was restricted to a half-mile segment of the creek just above Mammoth Pool Reservoir. 

It is not known exactly when the area was worked, but 

refuse around a large cabin still standing at the site 

indicates activity between 1920 and 1940, probably during the Depression.

The Mill Creek placer deposits are on a relatively 

flat bluff 500 feet above the San Joaquin River (fig. 7). 

The principal workings at the older placer operation 

are several trenches cut into thick soil cover on the ridge 

north of Mill Creek. These trenches (fig. 8), presently 

3-8 feet deep and as much as 250 feet long, are mostly 

oriented in north to northwest directions, transverse to 

the ridge crest. Large quantities of soil were apparently 

moved to Mill Creek for sluicing. Gravel piles along the 

creek indicate that stream sediments were also placered. 

The only gold detected in our samples from the Mill 

Creek area, 1.4 ppm, was in a panned concentrate of soil 

(227-P) from near the trenched area north of lower 

Mill Creek. Ten stream-sediment samples (three of 

them panned) from Mill Creek and its tributaries contain less than 0.02 ppm gold. Analyses of a sample of 

granitic bedrock and of a quartz vein upstream from the 

Mill Creek placers likewise show no gold.

The absence of gold upstream from this deposit (fig. 

10) indicates that gold in the soil cover was not derived 

from present-day Mill Creek headwaters. Nor is there 

any indication that the gold is derived from in situ

6 S.

weathering of a lode deposit in the granitic rocks of 

the ridge. Quartz veins are scarce on the ridge: an 

analysis of the bedrock (sample 225, table 3) shows no 

gold anomaly, and geologic mapping indicates no geologic features that would favor a lode deposit in this 

area (Huber, 1968). The Mill Creek deposit is probably 

an erosional remnant of a very old bench placer that 

was formed several million years ago along the ancestral San Joaquin River. Doubtless river gravels once
14 SIERRA DEMONSTRATION PROJECT AREA

were present, but they have been removed by erosion, 

leaving behind the gold they contained. During a long 

period of weathering and erosion this gold apparently 

mixed with upper parts of a deep soil that formed from 

the underlying granitic bedrock. Some of this gold may 

have been secondarily concentrated downslope in the 

gravels of Mill Creek.

No production figures were found for the Mill Creek 

of the project area even though Minerals Yearbooks for 

the years 1932-35 and 1938 indicate a production from 

"Mill Creek" of 102.62 ounces of gold and 9 ounces of 

silver (U.S. Bureau of Mines, 1933-68). Microfilm 

copies of original Bureau of Mines records indicate, 

however, that this "Mill Creek" is a different stream, 

40 miles to the south, north of Dunlap.

The gold remaining in the Mill Creek area is very 

sparse, and recovery of additional gold does not appear 

economically feasible. The Mill Creek deposit is, however, geologically important as an example of a type of 

gold placer that may exist elsewhere along the San 

Joaquin Eiver. Any flat or dissected river-cut bench 

along the Sail Joaquin River could contain placer gold 

deposits of the Mill Creek type.

QUARTZ

Quartz deposits in the project area are of two types: 

(1) numerous small quartz veins that cut metamorphic 

and granitic bedrock and (2) older quartz-pegmatite 

segregations related to late stages in cooling and 

crystallization of the granitic rocks.

Only the quartz pegmatite masses are large enough 

and pure enough to be of potential economic value. The 

Medley quartz claims, near Pincushion Peak, have been 

explored by Mr. John Medley, who reported having 

sold several shipments of quartz of piezoelectric 

quality.

The unpatented Medley quartz claims are on the west 

slope of Pincushion Peak at about 8,600 feet elevation. 

A road has been opened to the mine area, considerable 

overburden has been removed, and a shallow shaft sunk. 

The quartz is highly fractured and is embedded in a matrix of white clay that has resulted from weathering of 

originally abundant alkali feldspar. The quartz consists 

of both clear rock crystal and smoky quartz. A few large 

thin blades of a resinous mineral tentatively identified 

as ilmenite occur in some quartz crystals. Although the 

bedrock is very highly weathered and a thick soil has 

developed, it is still apparent that this deposit is part of 

a quartz-core pegmatite dike that cuts the grandodiorite 

of Lake Edison. The dike ranges in thickness from 3 to 4 

feet, strikes about N. 60° W., and dips 5°-25° N. Quartz 

appears to be concentrated near the footwall of the dike. 

The weathered dike is exposed over a length of about 80 

feet, but its extent at depth is unknown. A comparison

with other pegmatites of the project area suggests that 

this mass may have been lens shaped; if so its extent at 

depth probably does not exceed 80 feet. The site was inactive in 1969.

Other large masses of quartz are exposed 1 mile west 

of the Pick and Shovel mine (along the contact between 

the alaskite of Graveyard Peak and the quartz monzonite of Recess Peak) and on the east slope of the prominent ridge 1 mile east of Devil's Bathtub. These deposits 

consist predominantly of milky quartz of no economic, 

value.

SAND AND GRAVEL

Small deposits of sand and gravel are found along 

stream bottoms and in areas of glacial outwash. Other 

local deposits include the tailings from construction of 

Ward Tunnel under Kaiser Ridge. No commercial use 

is made of these materials except by summer residents 

for concrete aggregate.

ORNAMENTAL STONE

The coarse- to medium-grained granitic rock found 

over much of the project area is a potential source of dimension and ornamental stone but is of no commercial 

value owing to the remoteness of the area and to the presence of similar rock at more accessible localities.

Small deposits of travertine are found locally around 

hot mineral springs. Most of this rock is soft and punky, 

but at some localities, particularly along the San Joaquin River north of Crater Lake (near sample 180, fig. 

9), small amounts of dense beautifully banded yellow 

and orange onyx are present in the precipitates of inactive hot springs. The onyx deposits are too small and 

inaccessible for commercial exploitation, but could provide small amounts of ornamental stone for hobbyists.

DISTRIBUTION OF METALS IN THE SIERRA 

DEMONSTRATION PROJECT AREA

The chemical analyses of stream-sediment and bedrock samples provide a detailed picture of the distribution of metallic elements throughout the project area. In 

conjunction with geologic considerations, these analyses 

indicate that of the 30 metals for which analyses were 

made (see section "Analytical Methods and Procedures"), only gold, tungsten, copper, silver, tin, and 

molybdenum have possible economic importance in this 

area. The locations of samples and the abundance of 

these six elements are shown in figures 9-14. The data 

in figures 10-14 are taken from tables 1-3.

The distribution of arsenic was also plotted because 

initially we thought it might serve as a tracer, but we 

found no correlation between its abundance and the 

abundance of more valuable metals. In many places ar-
MINERAL RESOURCES 15

senic appears to reflect the presence of arsenic-rich mineral springs.

GOLD

Analyses of metamorphic bedrock show traces (up to 

0.08 ppm) of gold. The highest bedrock gold content, 

0.90 ppm, is from a single sample (169) of volcanic breccia on Volcanic Knob. This content is unexplainably 

high and may be the result of sample contamination. 

Analyses of quartz veins in the project area showed gold 

content to range from less than 0.02 ppm to only 0.08 

ppm. The relative abundance of gold in the stream sediments does not appear to be closely dependent on bedrock 

lithologies but instead depends on physiography and the 

complex transport mechanisms of streams and glaciers. 

Chemical analyses of stream sediments show that small 

amounts of gold (0.02-0.20 ppm) are widespread 

throughout much of the area. Concentrations higher 

than these are rare; most are restricted to the Kaiser 

Creek basin, the bench placer north of Mill Creek, 

streams immediately north of Huntington Lake (samples 3022, 3023), and the San Joaquin Kiver below 

Mono Hot Springs (sample 004). Areas in which most 

stream gravels contain low amounts of gold (0.02-0.20 

ppm) are 1 mile northeast of Mount Givens, a large 

area northwest and west of Lake Edison, the area surrounding Hoffman Meadow north of Kaiser Creek, and 

the east end and south slope of Kaiser Ridge.

TUNGSTEN

Among the bedrock samples, tungsten in measurable 

amounts is found only in samples of metamorphic rocks 

on the Lucky Blue claims (see section "Tungsten Mines 

and Prospects Along Kaiser Ridge"), in two mineralspring precipitates (003 and 1149), in one sample of 

Mount Givens Granodiorite (1033), and in two samples (068 and 165) of quartz veins, which contain 600 

and 480 ppm, respectively. The tungsten-bearing mineral in these veins was not identified. Most quartz veins 

analyzed contain little or no tungsten.

The distribution of tungsten in stream sediments 

clearly is related to the presence of metamorphic rocks 

upstream. Thus, high tungsten concentrations occur 

downstream from all metamorphic rocks except the 

metavolcanic rocks at the northeastmost corner of 

the area. High tungsten concentrations are also found 

in sediments from the North Fork of the San 

Joaquin River and from Granite Creek (figs. 9, 12, 

samples 193, 195, 1150). These values probably reflect 

metamorphic rocks and tungsten deposits northwest 

of the project area. Low tungsten values at other scattered localities probably reflect detrital tungsten-bearing minerals that were carried from distant metamorphic rock sources by glaciers.

COPPER

Copper contents of granitic bedrock samples range 

from less than 10 ppm in many granodiorites to 190 

ppm in a hornblende gabbro (sample 116); the granitic 

rocks average 12 ppm. Metamorphic rocks contain up 

to 186 ppm copper (sample 204) and average 27 ppm. 

Most quartz veins analyzed contain 10-50 ppm copper 

and one (sample 1111) contains 2,400 ppm.

Small amounts (10-20 ppm) of copper are widespread in stream sediments of the project area. These 

amounts are not anomalously high and generally can 

be explained by the presence of detrital concentrations 

of such minerals as hornblende and magnetite, which 

commonly contain copper in trace amounts, and by 

small amounts of copper adsorbed on clay minerals and 

organic matter (Hawkes and Webb, 1962, p. 122-125). 

Most stream-sediment samples from part of the area 

southeast of Pincushion Peak and northwest of Lake 

Edison, however, contain relatively high amounts of 

copper (to 88 ppm). Quartz veins are scarce in this 

area, and no sign of copper mineralization at the surface was noted. This area of high copper content is centered on a large mass of the granodiorite of Edison 

Lake and surrounds a central f acies of coarse-grained 

rock known as the quartz monzonite of Rock Creek 

Lake (Bateman and others, 1971). The copper anomaly 

here is probably explained by a slightly higher than 

normal copper content in these underlying granitic 

rocks.

SILVER

With the exception of a metavolcanic schist (sample 

204), an anomalous diorite dike rock (sample 231), and 

two mineralized rocks (samples 118, 127), the country 

rocks in the project area contain no detectable silver, 

and most quartz veins contain only minor amounts (to 

100 ppm), probably in argentiferous galena. Silver also 

is very sparse in stream sediments of the project area. 

It was detected in only 13 sediment samples, in amounts 

ranging from 0.5 to 2 ppm. Stream-sediment samples 

with high silver contents are from the northeast and 

southwest corners of the area. The silver in the southwest is probably alloyed with placer gold, whereas silver in the northeast appears related to abundant small 

argentiferous veins developed along northeast-southwest trending joints (p. 7).

TIN

Tin is rare in bedrock of the area and has been identified only in tactite samples from the Lucky Blue tungsten claims (samples 2532-34), in one metavolcanic 

rock (sample 204), in one hot-spring tufa deposit (sample 003), in one sample of vein quartz (sample 1111),

and in one specimen of altered diorite (sample 217). 

Nowhere was it found in sufficient abundance to be considered a potential resource.

Most stream sediments of the project area contain less 

than 10 ppm of tin. Thirty-four stream-sediment samples that contain 10 ppm or more are chiefly from 

streams that drain Kaiser Ridge, streams near a small 

quartz monzonite body east of Hoffman Meadow, the 

San Joaquin River and Warm Creek west of Lake Edison, and from streams in the vicinity of the Pick and 

Shovel mine.

MOLYBDENUM

Molybdenite, the principal ore mineral for molybdenum, is present in silicified and chloritized joints 

throughout the project area and is a common minor 

constituent of veins in the northeast half of the area. 

The molybdenum content of some small veins is as high 

as 1,500 ppm (sample 1111). Molybdenum is largely restricted to these narrow veins, and there is no evidence 

for molybdenum mineralization of surrounding wallrocks. Although most samples of granitic bedrock contain no detectable molybdenum, one sample of Mount 

Givens Granodiorite (1148) does contain 10 ppm molybdenum and several samples of the alaskite of Graveyard Peak contain as much as 15 ppm molybdenum. 

One sample of metavolcanic schist (204) contains 50 

ppm molybdenum, and mineral-spring deposits contain a maximum of 50 ppm. No deposits of commercial 

size or grade were found in the project area, although 

according to Mr. Jeff Winslow of Mono Hot Springs 

(oral commun., 1969) , prospectors have developed small 

pits and recovered minor amounts of molybdenite from 

chlorite-rich mineralized joints near Chamberlain Lake, 

in the southeast corner of the project area. A streamsediment sample downstream from this area (067) contains 100 ppm molybdenum, the highest value reported 

from any stream in the project area. Molybdenum in 

the range from 5 ppm (lower sensitivity limit) to 50 

ppm is, however, present in most stream sediments of 

the project area, except in those southeast of Kaiser 

Ridge. These values are significantly higher than the 

average values of 0.1-1 ppm reported for clastic sediments by Hawkes and Webb (1962, p. 369) and suggest a low molybdenum anomaly in the area. Only values of 10 ppm or greater are plotted in figure 14.

OTHER METALS

In addition to the six metals described above, 19 

others are listed in table 3, and their distribution can 

be plotted. Informal plots of these other elements show 

that none of them occur in concentrations suggesting 

potential resources in the project area.

Among these other metals, lead is one of the most

interesting, as it appears to be a sensitive indicator of 

the presence of mineralized veins. Lead is present in all 

stream sediments of the area in amounts generally ranging from 20 to 50 ppm. Amounts higher than this are 

unusual and are mostly found near the northeastmost 

corner of the project area, where galena-bearing veins 

are most abundant. Sediments from a small stream 

draining the Pick and Shovel mine area, for example, 

contain 700 ppm lead, and a sample from Minnow 

Creek, a major stream draining the northeast corner 

of the area, contains 300 ppm lead downstream from 

the Pick and Shovel mine.

Zinc also has potential as an indicator of mineralized 

areas, but the high threshold sensitivity value (200 

ppm) inherent in our analytical technique made evaluation by this element relatively useless in this study. 

Most high zinc values in streams are from areas near 

roads and bridges, where the zinc was probably derived 

from introduced contaminants, such as galvanized 

metal and batteries. The extraordinarily high value reported in stream sediment north of Huntington Lake 

(sample 3055) must reflect contamination, as high values do not appear downstream. Some zinc mineralization has occurred along the contact between the Mount 

Givens Granodiorite and meta volcanic rocks near Bear 

Creek Diversion Dam (table 3, sample 073 and 2031), 

and in tactites and diorite in the northeast corner of 

the area (samples 119,120, and 217).

Iron content aids in interpreting concentrations of 

certain other elements in stream samples and also in 

comparing analyses with one another. "Black sand" 

concentrates of heavy minerals such as magnetite, 

ilmenite, hornblende, and zircon tend to have higher 

than normal concentration of associated heavy-mineral 

elements such as gold, chromium, iron, lanthanum, vanadium, tungsten, and zirconium. The iron content, plotted first among the spectrographic analyses of table 3, 

is an excellent indicator of the degree to which heavy 

minerals have been concentrated in each sample, either 

through panning or natural stream processes. High 

iron content implies abundant magnetite and indicates 

that the concentration of associated heavy elements 

is generally higher than in stream sediment with low 

"black sand" content.

EVALUATION OF MINERAL RESOURCE POTENTIAL

Our study indicates that no mineral deposits of major 

commercial importance are present in the Sierra Demonstration Project area. The only mining claims in the 

area that are being worked are the Lucky Blue tungsten claims on Kaiser Ridge, the Rose-Kay gold placer 

claims on loAver Kaiser Creek, the industrial quartz 

claims on Pincushion Peak, and the Pick and Shovel
GEOLOGIC FEATURES AS NATURAL RESOURCES 29

mine claims north of Silver Divide. None of these is 

patented, and the average annual production is very 

small. At each of these claims small amounts of minable 

ore exist, but it is doubtful that any of them have sufficient reserves to support large-scale mining operations. 

Each of the known metallic deposits in the project 

area is accompanied by moderate to strong metal anomalies in downstream sediments (or associated sediment in the case of placer gold). Our geochemical sampling program would have indicated the presence of 

each of these deposits had they not already been known 

to exist. With the exception of low copper and molybdenum anomalies, no other significant metal anomalies 

were found in the project area, so it is unlikely that 

large ore deposits will be discovered in the future. 

Small bodies of tungsten-bearing tactite may be found 

associated with the metamorphic rocks of the project 

area, low-grade placer gold deposits may be found 

along streams at lower elevations, and small deposits of 

copper, lead, molybdenum, silver, or zinc ore may be 

found associated with the widespread quartz veins in 

the northeast third of the area; however, none of these 

potential deposits could be expected to support major 

mining.

GEOLOGIC FEATURES AS NATURAL RESOURCES

The tens of thousands of people who visit parts of 

the project area every year pass by some of the most 

interesting and educational geological features of the 

Sierra Nevada, but most visitors are unaware of this. 

These tourist features may have greater long-range 

value than the mineral resources of the project area. 

The following is a brief summary of a few of the geological features of general interest.

GLACIAL FEATURES

At least 90 percent of the project area was covered 

by ice at one time or another during the ice ages of the 

Pleistocene Epoch. The Pleistocene Epoch lasted for 

more than 2 million years and ended with the retreat 

of the last glaciers only about 10,000 years ago, so relics 

of those cold and forbidding times abound. Enormous 

trunk glaciers a thousand feet thick flowed down both 

the main San Joaquin River and its South Fork, cutting 

deeply into underlying rocks and depositing bouldery 

lateral moraines along their margins. Smaller alpine 

glaciers were widespread along Kaiser Ridge, Silver 

Divide, and the east margin of the project area and 

carved U-shaped valleys and steep-walled cirque basins, 

now occupied by glacial lakes. Giant boulders, some 

weighing a hundred tons, were left behind by these 

glaciers as they retreated; these erratics now litter much 

of the landscape. Some of these huge ice-transported

boulders can be seen along the road to Florence Lake 

in the immediate vicinity of the High Sierra Ranger 

Station. A few hundred feet east of the station, south 

of the road to Florence Lake, morainal ridges consisting 

of glacially transported boulders rest on a granitic bedrock surface that was polished and striated by rock 

debris carried along by the flowing ice.

Standing at this site, one can look directly north and 

clearly see on the opposite side of the South Fork of the 

San Joaquin River, 4 miles away, a huge lateral moraine 

that was deposited along the north margin of the ancient 

glacier that once occupied the river valley. This moraine 

extends from near Lake Edison westward for several 

miles and from a distance appears as a series of brushcovered, boulder-strewn green belts that contrast with 

the darker timbered areas above and below (frontispiece) . If one then were to turn around and look directly 

south, he would see a steep forest-covered slope rising 

1,200 feet above his level. This boulder-covered slope 

is the matching lateral moraine that formed on the south 

side of the glacier; this moraine is most clearly seen 

looking back from near Lake Edison. It takes little effort to imagine the flowing sea of thousand-foot-thick 

ice which once covered the South Fork between these 

two moraines.

VOLCANIC FEATURES

About three and a half million years ago, before the 

ice age of the Pleistocene Epoch, large volcanoes in the 

project area erupted huge quantities of basaltic lava 

that flowed downslope and along the ancestral valley of 

the San Joaquin River, which had not yet cut the deep 

inner canyon in which it now flows. Although erosion 

has removed most of this basalt, numerous remnants are 

preserved at the Brown Cone area near Kaiser Diggings, 

along Silver Divide from Pincushion Peak to Saddle 

Mountain, along Mono Creek, and at many localities in 

the broad valley of the South Fork of the San Joaquin. 

One of the best exposed and most easily visited remnants 

is Devil's Table, 1 mile northwest of Mono Hot Springs. 

Standing near the High Sierra Ranger Station and 

looking to the north, one can see the columnar-jointed 

Devil's Table and the high country beyond and can 

perhaps imagine the river of molten lava which once 

flowed down into the San Joaquin River from a volcano 

several miles up Mono Creek. From here other basalt 

flows can also be seen west of Devil's Table, along Silver 

Divide, and in the Volcanic Knob area of upper Mono 

Creek.

Visitors to the project area may notice fragments of 

rhyolite pumice scattered about the ground and concentrated in natural depressions. These fragments are 

mostly restricted to the east half of the Kaiser Peak and
30 SIERRA DEMONSTRATION PROJECT AREA

west half of the Mount Abbot quadrangles and are increasingly abundant northward. In some places north of 

Silver Divide, pumice deposits are more than 1 foot 

thick. This pumice records a violent volcanic eruption 

which occurred to the north, in the Mammoth Lakes 

area, several hundred years ago. Vast quantities of 

pumice and gas were blown high into the air, and northerly winds carried the fragments southward into and 

across the project area. Fragments of this pumice can 

be found in sandy depressions in granitic bedrock at 

many easily accessible localities, including Kaiser Ridge 

between Kaiser Pass and Mount Givens and near the 

High Sierra Banger Station.

MINERAL SPRINGS

A small area around Mono Hot Springs has long 

been famous for its mineral baths. Mineral springs also 

are common along the South Fork of the San Joaquin 

River from Mono Hot Springs northwestward for about 

12 miles, although the springs to the northwest are not 

as hot as those of Mono Hot Springs. Over several thousand years the mineral waters have built up thick travertine mounds; 2 miles west-northwest of Mono Hot 

Springs, for example, in a small area on the north 

bank of the San Joaquin River, brightly colored travertine formations have formed a delicately terraced landscape that is similar to parts of Yellowstone National 

Park.

GOLD DEPOSITS

The low-grade gold placers along Kaiser Creek (see 

section "Gold Placer Deposits of Kaiser Creek") have 

far greater recreational than commercial potential. During this mineral investigation, several families were observed panning gold along the creek. Although no one 

is likely to recover more than a few cents worth of gold 

without a major effort, a weekend gold-panning trip 

can be an enjoyable venture.

Averages for each group of analyses calculated as arithmetic mean of the reported values, arbitrarily assuming Nr=O, L = one-half lower 

determination limit, and G = upper determination limit; parentheses indicate averages were derived from too few values to be reliably represented. Most chemical analyses by J. G. Viets ; others by R. N. Babcock, R. R. Carlson, R. B. Culbertson, J. G. Frisken, J. R. Hassemer, H. D. 

King, R. W. Leinz, R. L. Miller, D. G. Murrey, M. S. Rickard, L. A. Vinnola, and A. W. Wells. Spectrographic analyses by B. F. Cooley, G. W.
