DESCRIPTION OF MAP UNITS

ALLUVIAL DEPOSITS

Alluvium (Holocene)—Very recent unconsolidated deposits of 

locally derived sand, silt, clay, and minor gravel of modern 

flood plains and stream channels that occupy post-1880 

arroyo floors. Thickness generally less than 2 m

Alluvium (Holocene)—Sand, silt, clay, and gravel of several cutand-fill deposits, roughly 1 m higher than unit Qam, 

dissected by post-1880 arroyos. Includes eolian sand and 

residuum in places. Radiocarbon ages from deposits along 

Park Wash and Kitchen Corral Wash (east part of 

quadrangle north of U.S. Highway 89) indicate five 

depositional phases beginning at 6,320, 5,650, 5,390, 

4,330, 2,145, and 340 yr B.P. Narrow belts of unit Qam

are mapped with unit Qah in western part of map area

Alluvium, undivided (Holocene and Pleistocene)—Sand, 

gravel, silt, and clay at various altitudes; not correlated with 

alluvial deposits described below

Younger alluvium (Holocene? and Pleistocene?)—Weakly to 

moderately consolidated deposits of sand, gravel, and 

gravelly sand. Forms low terraces 5–10 m topographically 

higher than unit Qah. Thickness 5–20 m

Intermediate alluvium (Pleistocene)—Moderately consolidated 

deposits of gravel, gravelly sand, and coarse sand. Forms a 

moderately dissected intermediate-height terrace as much as 

25 m topographically higher than unit Qay. Thickness 

5–40 m

Older alluvium (Pleistocene)—Firmly consolidated deposits of 

gravel, sandy gravel, and coarse sand. Occurs in 

moderately dissected terraces and pediments higher than 

unit Qai; on larger streams terrace is roughly 50–70 m 

above stream channel. Highest deposits may be of late 

Tertiary age. Thickness 10–50 m

Alluvium (Pleistocene or Pliocene)—-Firmly consolidated 

gravel and sand deposits; contains pebbles and cobbles of 

mostly gray and red quartzite and silicified limestone. 

Preserved in stream terrace remnants west of Sevier fault 

zone at heights of 50–120 m above present streams. Age 

uncertain

EOLIAN DEPOSITS

Eolian sand in active dunes (Holocene)—Light-gray, 

yellowish-gray, and reddish-orange, fine to medium, wellsorted sand composed mostly of quartz; largely derived 

from Navajo Sandstone

Eolian sheet sand, alluvium, and residuum (Holocene and 

Pleistocene)—Sand as in unit Qesh, in widespread, mostly 

stabilized sheets and as fillings of topographically low areas. 

Lacks dune morphology; locally includes small bedrock 

outcrops, slope-wash deposits on gently sloping surfaces, 

residuum, and locally derived sand and silt deposited by 

minor intermittent streams and washes

Eolian sand in mostly inactive dunes (Holocene and 

Pleistocene)—Sand as in unit Qesh, but mostly reddish 

orange; in mostly vegetation-stabilized climbing and falling 

dunes (sand ramps and aprons) that flank buttes and mesas, 

and as small dune fields in canyons or in lowland areas; 

largely derived from Navajo Sandstone. May be as much as 

15 m thick in places. Includes gently sloping areas 

modified by slope wash

MASS-WASTING DEPOSITS

Colluvium, undivided (Holocene and Pleistocene?)—Poorly 

sorted debris flow, talus, and rockfall deposits of sand and 

angular to subangular blocks of rock as unsupported masses 

and as clasts in clayey matrix, and small landslide deposits. 

Includes clayey weathering residuum and slope wash in 

some areas, such as west of Meadow Creek, south of Utah 

State Highway 9

Landslide slump-block deposits (Holocene and 

Pleistocene)—Essentially coherent, slumped and rotated 

blocks of bedrock, such as Toreva blocks, overlying 

incompetent units such as Petrified Forest Member of 

Chinle Formation, Entrada Sandstone, and Tropic Shale. 

Includes relatively small landslide sheet deposits in some 

areas

Mass landslide sheet deposits (Holocene and 

Pleistocene)—Large coherent blocks of rock in a matrix of 

smaller clasts and clay, locally exhibiting landslide scarps, 

sag areas, and downslope creep surface textures. 

Thickness largely unknown due to poor exposures, but in 

part at least as much as 24 m thick. Originates in and 

mostly overlies incompetent units, notably the Tropic Shale, 

Dakota, and Chinle Formations. Includes small unmapped 

areas of alluvial, pond, and slope-wash deposits, and 

surface slump material

IGNEOUS ROCKS

Olivine basalt (Holocene and Pleistocene)—Medium- to darkgray, dense to vesicular basalt as blocky lava; includes 

downslope concentrations of blocks that may be flow 

margins or talus; contains phenocrysts and groundmass 

minerals of olivine, labradorite, titaniferous augite, and irontitanium oxides. Minor basalt dikes as local features. Flows 

occur on topographic benches and in part along present 

stream valleys. Radiometric age of basalt along Tenny 

Creek (26 km east-northeast of Glendale) is 1.1 Ma; basalts 

in western part of quadrangle are 0.36, 0.56, and 0.8 Ma 

(Best and others, 1980). Maximum thickness of unit Qb

probably about 20 m

Cinder cones and vents—Gray, black, and red cinders, 

scoria, and minor volcanic bombs

SEDIMENTARY ROCKS

Brian Head Formation (sandstone and conglomerate unit 

as revised in Sable and Maldonado, 1997) (lower 

Tertiary)—Sandstone, conglomerate, mudstone, and minor 

limestone, shale, and clay. Mostly slope forming; weathers 

drab gray and brown; includes pale-orange to yellowish 

gray conglomerate that contains moderately well rounded 

pebbles and cobbles of chert, quartzite, and limestone, and 

litharenite that is poorly sorted, strongly crossbedded, and 

poorly to moderately indurated. Lowermost beds are 

yellowish-orange-weathering clay and siltstone. Lower 

contact appears to be abrupt and may be an unconformity. 

Maximum exposed thickness of unit is about 120 m

Claron Formation (lower Tertiary)—Forms the Pink Cliffs. 

Consists of two mapped informal units described below. 

Previously referred to as Wasatch Formation (Cashion, 

1967) or Cedar Breaks Formation (Hintze, 1973) within 

the quadrangle or in adjoining areas. Maximum thickness 

about 300 m. Base is a low-angle regional unconformity. 

Apparent sparsity of primary depositional features 

suggested to Mullet and others (1988) that pedogenic 

processes have largely altered the original strata of fluvial 

and lacustrine origin

White limestone unit—Limestone and minor limy shale and 

chalky clay that forms cliffs and steep slopes. Limestone is 

white to very light gray, massive, in part brecciated; calcitefilled solution cavities, vugs, calcite veins, and dolomitic 

patches are common. Thickness about 20–40 m

Lower unit—Largely limestone and limy mudstone, and 

lesser channel-form sandstone and conglomerate, siltstone, 

limestone breccia, and dolomite; mostly vivid to pale pink 

to orange and light to very light gray; bedding features are 

absent to poorly defined in carbonate rocks, which exhibit 

mottled to nodular textures and calcite veins and vug 

fillings; root casts and oncholites occur in some beds; 

locally contains very rare casts and molds of gastropods 

and pelecypods. Well-rounded pebbles and cobbles in 

conglomerate are abundant mostly in eastern parts of 

quadrangle, such as Bryce Canyon area. Locally weathers 

to spectacular cliffs, columns, and spires. Uppermost beds 

are about 15 m of reddish-orange claystone and siltstone 

underlain by about 30 m of light-gray limestone; in places 

west of the Sevier fault zone these beds were mapped by 

Cashion (1967) as the “uppermost prominent light-gray 

ledge-forming limestone,” but elsewhere this unit name 

was applied to unit Tcw. Basal beds, 0 to about 30 m 

thick, consist of yellowish-orange-weathering shale, 

claystone, and siltstone, possibly equivalent to the Pine 

Hollow Formation (Bowers, 1972), underlain by gray, wellindurated quartzose conglomerate and sandstone that is 

possible equivalent of the Canaan Peak Formation 

(Bowers, 1972).

Elsewhere, basal beds in some places are pink to 

reddish-orange limestone breccia. Thickness of unit about 

250 m; east of Sevier fault zone thickness is as little as 150 m

Kaiparowits(?) Formation (Upper Cretaceous)—Sandstone, 

clay, mudstone, minor ironstone lenses and concretions 

and limestone-clast conglomerate. Sandstone; subarkose 

to litharenite; drab yellowish-gray to medium-gray, salt-andpepper appearance, and clay matrix; weathers brownish 

gray with earthy bluish appearance; contains abundant 

small- to medium-scale trough crossbeds; contains lesser 

amounts of yellowish-orange-weathering, fine-grained 

sandstone lenses. Clay and mudstone are mostly medium to 

dark gray, in part carbonaceous, containing a few pale-red 

beds. Unit contains scattered vertebrate (probably dinosaur) 

bones, poorly preserved pelecypod shells, and plant 

fragments. Basal contact characteristics are vague; unit 

appears to interfinger with underlying Wahweap Formation. 

Estimated thickness 0 to about 75 m; absent or 

intermittently present in vicinity of, and east of, Sevier fault 

zone. Depositional environment: upper(?) alluvial plain. 

Palynology indicates that Kaiparowits(?) Formation in 

Markagunt Plateau is of mid-Coniacian through Santonian 

age, older than typical Kaiparowits Formation (Campanian) 

in southern Kaiparowits Plateau (Nichols, 1997)

Wahweap Formation (Upper Cretaceous)—-Slope- and ledgeforming shale, clay, siltstone, and sandstone; minor 

concretionary limonite, carbonaceous shale, silty limestone, 

and clay-gall and limestone-clast conglomerate. Shale and 

clay are medium to light gray and pale red, having a 

relatively high clay mineral content. Sandstone constitutes 

about 10–25 percent of unit, mostly in lower part; is mostly 

fine to medium grained, subarkosic, trough crossbedded, 

calcareous; commonly weathers to vivid yellowish orange 

hues; is mostly well indurated but less indurated and coarser 

grained in upper part; occurs in beds mostly less than 5 m 

thick but as much as 15 m thick. Lenticular channel-fill 

sandstone is common and most abundant between Meadow 

Creek and East Fork of Virgin River. Formation contains 

sparse fresh-water pelecypods and gastropods and limonitic 

wood fragments. Formation thins eastward to feather edge. 

Basal contact drawn at top of quartzose sandstone and 

conglomerate (Drip Tank Member equivalent) at top of 

upper unit of Straight Cliffs Formation. Thickness about 

100–200 m east of Sevier fault zone and about 245–305 m 

west of zone. Depositional environments: upper(?) alluvial 

plain, fluvial and lacustrine 

Straight Cliffs Formation, upper unit (Upper Cretaceous)— 

Slope- and ledge-forming, interbedded claystone, mudstone, 

siltstone, sandstone, conglomerate, and minor ironstone, 

limestone-clast conglomerate, carbonaceous shale, and thin 

coal beds. Sandstone forms 10–30 percent of unit; is 

yellowish gray, subarkosic, fine-grained to very coarse 

grained, moderately to poorly sorted; moderately indurated; 

weathers to drab light-brown to pale-yellow tabular sets of 

beds having cavelike, fretted reentrants; has low- to 

moderate-angle trough crossbeds and commonly contorted, 

convolute bedding. Finer-grained lithologies are commonly 

light to medium gray and minor pale red and reddish brown. 

Upper unit consists of three subunits (not mapped 

separately): upper, middle, and lower. Upper subunit is 

distinctive interbedded gray quartzose sandstone and granule 

to pebble conglomerate that contains well-rounded, resistate 

clasts, is moderately indurated, weathers to low-angle slopes 

and saddles and is 15–30 m thick. This upper subunit is 

interpreted to be the Drip Tank Member of the Straight 

Cliffs Formation of the Kaiparowits Plateau (Peterson, 

1969). Middle subunit forms steep slopes and ledges; 

contains sandstone cliffs as much as 25 m high, especially 

in area between Muddy Creek and East Fork of Virgin River, 

where sandstone is about 35 percent of subunit; sandstone 

is much less abundant in westernmost areas of quadrangle. 

Middle subunit, about 240–245 m thick, contains thin coal 

beds and is interpreted to be roughly equivalent to John 

Henry Member of Straight Cliffs Formation of Kaiparowits 

Plateau (Peterson, 1969). Lower subunit is slope forming, 

approximately 50- to 75-m thick, mostly poorly resistant 

mudstone and siltstone and minor Ostrea-bearing limestone 

and sandstone; interpreted to be an approximate correlative 

of the Smoky Hollow Member of the Straight Cliffs 

Formation of the Kaiparowits Plateau (Peterson, 1969). 

Basal contact of unit placed at top of uppermost cliffforming sandstone of the lower unit of Straight Cliffs, 

believed to be generally coeval throughout map area. A 

distinctive sandstone and conglomerate about 15 m thick, 

similar to the Drip Tank Member equivalent, occurs in 

places in lower part of middle subunit; it is tentatively 

correlated with the Calico bed of Peterson (1969). Middle 

and lower subunits contain sparse mollusks, wood 

fragments, and plant impressions. Total thickness of unit 

about 300–380 m; thickest in areas of abundant sandstone. 

Depositional environment: lower coastal plain or lower 

alluvial plain; Drip Tank equivalent probably of braided 

stream system origin

Straight Cliffs Formation, lower unit (Upper Cretaceous)— 

Predominantly cliff-forming sandstone; fine to medium 

grained, well sorted, quartzose, calcareous, medium gray to 

grayish orange; weathers grayish orange and dark yellowish 

orange; in medium to very thick planar beds and low-angle 

crossbeds; interbedded with shale, mudstone, and silty to 

sandy limestone. Shale, in part carbonaceous, contains thin 

coaly lenses and lenses of coquinoid Ostrea-bearing organic 

limestone. Fossils include pelecypods, ammonoids, and 

trace fossils; bioturbation features are locally common. Unit 

is approximately equivalent to Tibbet Canyon Member of 

Straight Cliffs Formation of Kaiparowits Plateau (Peterson, 

1969) east of the mapped area. Thickness varies from 

about 25 m to as much as 100 m; unit thickens westward 

mostly by intertonguing with underlying Tropic Shale from 

about 50 m to as much as 180 m. Depositional environments: mostly marine shoreface and foreshore with minor 

lagoon or bay influence

Straight Cliffs Formation, undivided (Upper Cretaceous)— 

Mapped in eastern part of quadrangle, east of Slide 

Canyon; includes both upper and lower units of Straight 

Cliffs where lower unit is too thin (generally less than 15 m) 

to portray at scale of map. Lithologies similar to those 

described above. Total thickness about 300–340 m; 

uppermost subunit (Drip Tank Member equivalent) is about 

30–50 m thick

Tropic Shale (Upper Cretaceous)—Slope-forming, drab, thinbedded mudstone that weathers gray to olive gray and 

yellowish gray; dark upper part generally has higher organic 

content than lower part; bentonitic mudstone in lower part. 

Minor carbonaceous shale and coal occur in western part of 

quadrangle. Generally west of Muddy Creek (north of Mt. 

Carmel Junction), successions of cliff-forming, yellowishgray quartzose sandstone as much as 50 m thick having 

planar beds to low-angle crossbeds occur in lower part and 

thinner successions are present in uppermost part. 

Limestone and calcitic septarian limestone concretions are 

locally present. Unit contains marine fossils ranging in age 

from upper Cenomanian to Turonian. The Tropic grades 

into, and interfingers with, overlying Straight Cliffs 

Formation mostly west of Muddy Creek; its basal contact is 

placed at top of an upper coal zone of Dakota Formation 

(Cashion, 1967). Thickness variable, but Tropic generally 

thickens eastward from about 90 m to more than 305 m. 

Depositional environments: mostly marine offshore, 

grading upwards to foreshore and shoreface

Dakota Formation (Upper and Lower? Cretaceous)—Slopeto ledge-forming, interbedded mudstone and sandstone, and 

minor but distinctive bentonitic mudstone, coal, conglomerate, and ironstone. Mudstone is gray to very dark gray, 

brown, and olive gray; sandstone is mostly yellowish-gray to 

light-gray litharenite, moderately cemented, lenticular, 

trough crossbedded, and resistant. Two or three coal beds 

as much as 1.5 m thick occur in eastern part of quadrangle, 

and two persistent coal zones having coal beds as much as 

5.5 m thick are present along the southern Markagunt and 

Paunsaugunt Plateaus (Cashion, 1961, 1967; Doelling, 

1972). Conglomerate as much as 25 m thick is common as 

channel fills in basal part of formation; contains wellrounded clasts of resistate chert, quartzite, limestone, 

silicified logs, and organic “trash,” some of which is 

uranium bearing. Diverse fossil pollen assemblage from 

lowermost part of formation suggests Barremian and Aptian 

ages, and pollen from middle part suggests late Albian to 

late Cenomanian age (Doelling and Davis, 1989, p. 73); 

marine pelecypods and scarce ammonoids occur in lower 

and upper parts of the Dakota. Base of formation 

corresponds to K–0 unconformity of Pipiringos and 

O’Sullivan (1978). Thickness east of Muddy Creek is about 

60–75 m; thickens westward to about 230 m in northwest 

corner of quadrangle. Depositional environments are 

varied: fluvial, lagoonal, brackish to marine shoreface, 

foreshore and offshore(?) marine

Entrada Sandstone (Middle Jurassic)—Ledge-forming 

sandstone and minor interbedded siltstone and claystone; 

mostly light to medium light gray, fine to medium grained, 

quartzose, round to subround; moderately indurated, with 

calcareous, siliceous, and iron-oxide cement; in part 

containing medium- to large-scale, wedge-planar crossbeds.

near Hildale

Lamb Point Tongue of Navajo Sandstone (Lower Jurassic)— 

Predominantly sandstone similar to that in Navajo 

Sandstone; conformably lies between Tenny Canyon 

Tongue and main part of Kayenta Formation; mapped only 

where overlain by unit Jkt; contact between unit Jnl and 

lower part of unit Jn is an artificial cutoff. Mapped from 

approximately west of Johnson Canyon to Moquith 

Mountains; thins westward from about 150 m to about 85 

m; farther west, it is about 8 m thick in the vicinity of 

Hildale, where it is mapped with Kayenta Formation

Kayenta Formation, main unit (Lower Jurassic)—Widespread

Kayenta unit is about 35–45 m thick in south-central part of 

quadrangle, and about 200 m thick in westernmost 

exposures. Depositional environment: alluvial plain

Moenave Formation (Lower Jurassic)—In southwestern part 

of quadrangle consists of Springdale Sandstone, Whitmore 

Point, and Dinosaur Canyon Members; in south-central and 

southeastern parts consists of members not mapped 

separately in either area. Springdale Sandstone Member is 

cliff-forming, pale-reddish-brown to pale-red, fine-grained to 

very fine grained sandstone; blocky to massive, with trough 

crossbeds, ripple marks, and mud cracks; contains 

distinctive lenses of claystone- and siltstone-pebble 

conglomerate and minor thin siltstone and mudstone 

partings; locally intertongues with underlying Whitmore 

Point Member and, where that member is absent, with 

Dinosaur Canyon Member. Thickness of Springdale is

30–35 m in southwestern part. Whitmore Point Member, 

present west of Johnson Canyon, is greenish-gray to 

grayish-red, thin-bedded siltstone, variegated claystone, and 

interbedded thin sandstone beds similar to those in the 

Springdale; contains fresh-water fish remains that have 

been considered to be of Triassic age and palynomorphs 

dated as Early Jurassic (Peterson and Pipiringos, 1979, p. 

B31). Whitmore Point is slope-forming and forms a 

reentrant below the Springdale; thickness is 0 to about 15

(Lower Jurassic) less than 2 m thick has been reported at 

base of the Moenave at the Managanese King Mine, about 

2 km west of the eastern quadrangle boundary (Doelling 

and Davis, 1989, p. 41). West of this, the Moenave 

Formation or intermittent, very thin Wingate, mapped with 

the Moenave, overlies Chinle Formation. Depositional 

environments: alluvial flood plain and lacustrine. Total 

Moenave thickness is about 150 m in southwestern part 

and about 100–130 m in south-central and eastern areas

and manganese-rich nodules. Sandstone has clay matrix; 

contains silicified logs and log fragments. Rocks of member 

are extremely slippery and unstable when wet, forming 

unstable slopes prone to landsliding. Member ranges in 

thickness from about 130–240 m. Depositional 

environments: lacustrine and fluvial with volcanic influx

Shinarump Sandstone Member—Cliff- to ledge-forming, 

gray, yellowish-gray, and grayish-orange sandstone and 

conglomerate having low- to moderate-angle trough

in southeastern part of quadrangle. About 275–300 m 

thick in eastern areas; thickens westward. Base is d–1 

unconformity of Pipiringos and O’Sullivan (1978). Mapped 

as undivided Moenkopi in southeast corner of quadrangle 

because of narrow outcrop belts due to steep dips; there, 

however, the Timpoweap Member is mapped separately

Upper red member (Middle? and Lower Triassic)— 

Reddish-brown to light-brown siltstone and very fine grained 

to fine-grained sandstone having a clayey matrix; in part 

calcareous and micaceous; includes interbedded mudstone;

Davis, 1989, p. 35), thickens westward; lower contact is 

conformable and gradational. Depositional environments: 

lower coastal plain, tidal flat, sabkha

Middle red member (Lower Triassic)—Poorly resistant, 

slope-forming, medium-red to reddish-brown mudstone and 

siltstone containing veinlets and thin seams of gypsum and 

lesser fine-grained and silty sandstone; gypsum increases

Virgin Limestone Member (Lower Triassic)—Limestone, 

dolomite, sandstone, shale and mudstone; dolomitic 

limestone and dolomite are mostly yellowish gray, mostly 

micritic, in part oolitic; birdseye structure locally present; 

ledge forming. Sandstone is yellowish-gray with small-scale 

crossbedding. Shale, siltstone, and mudstone are brownish 

gray, generally calcareous. Member forms low hogbacks 

and caps low buttes; contains locally abundant pelecypods, 

gastropods, crinoid columnal fragments, and scarce Early 

Triassic ammonite Tirolites. Lower contact is apparently 

gradational. Member is about 4–10 m thick (Doelling and 

Davis, 1989, p. 34), thickening westward. Virgin 

Limestone Member is widespread but too thin to map as a 

separate unit; outcrop of this thin member along the 

vaguely exposed contact between units dmm and dml in 

southeastern part of map area is indicated by line 

decoration Depositional environment: very shallow, 

restricted, low-energy marine

Lower red member (Lower Triassic)—Slope-forming, 

reddish-brown to grayish-red and grayish-brown siltstone 

and interbedded fine-grained, arkosic, micaceous, 

calcareous sandstone; ripple marks and small-scale 

crossbeds common; unit generally coarsens upwards. About 

43–67 m thick (Doelling and Davis, 1989, p. 34), 

thickening westward. Depositional environment: similar to 

that of upper red member, probably coastal plain

Timpoweap Member (Lower Triassic)—-Ledge- to cliffforming, tan to yellowish-gray limestone, dolomitic 

limestone, dolomite, calcareous sandstone, siltstone, chert 

breccia, and chert granule- to pebble- conglomerate; minor 

yellow shale; thin to thick bedded; lower contact with 

underlying Kaibab Formation is a disconformity commonly 

marked by a 1- to 2-m-thick chert breccia and (or) 

conglomerate; contact locally difficult to recognize because 

lithologies of underlying and overlying beds are similar. 

Thickness of Timpoweap about 6–15 m (Doelling and 

Davis, 1989, p. 32). Base is d–1 unconformity of 

Pipiringos and O’Sullivan (1978). Depositional 

environments: very shallow, restricted(?) marine shelf and 

lower coastal plain having low-energy stream input

Kaibab Formation (Lower Permian)—Upper part is slope- and 

ledge-forming, gray to yellowish-gray limestone, dolomitic 

limestone, dolomite, sandstone, and banded chert; thickness 

about 24 m. Gypsum beds in western areas. Best exposed 

in Kaibab Gulch. This is the informal Alpha member of 

McKee (1938) and the Harrisburg Member of Nielson 

(1981). Underlain by about 60 m of cliff-forming, gray, 

cherty limestone (80 percent) and calcareous, tan to gray, 

fine- to coarse-grained sandstone; chert occurs as white and 

brown spherical nodules, irregular masses, and tabular 

layers in limestone and sandstone. Corals, brachiopods, 

bryozoans, and crinoids common in some limestone beds.

Member of Nielson (1986). Lower part is cliff-forming, gray 

to yellowish-gray limestone, siliceous to arenaceous, in part 

containing gray chert as nodules, irregular masses, and 

tabular bands; includes lesser amounts of calcareous 

sandstone. Fossils consist mostly of large brachiopods 

locally abundant in limestone; unit is 30 m thick. This is the 

Brady Canyon Member of Nielson (1981). Depositional 

environments: coastal plain, restricted marine, and open 

marine; breccias possibly post-depositional due to solution 

of evaporite beds. Upper and lower parts similar to upper 

and lower parts, respectively, of overlying Kaibab Formation
