Depth to secondary calcium carbonate: 1 to 4 inches
Depth to lithic contact: 5 to 20 inches to sandstone or shale bedrock
Particle-size control section: 18 to 27 percent clay and 35 to 90 percent rock fragments (consisting of channers, flagstones, and stones from sandstone and shale)
A horizon:
Hue: 10YR or 2.5Y
Value: 5 to 7 dry, 4 or 5 moist
Chroma: 2 to 4 dry or moist
Texture (fine earth): loam
Rock fragments: 60 to 80 percent channers, flagstones, and stones.
Reaction: moderately alkaline or strongly alkaline
Bk horizon:
Hue: 10YR or 2.5Y
Value: 5 to 7 dry, 4 to 6 moist
Chroma: 2 to 4 dry or moist
Texture (fine earth): loam
Rock fragments: 35 to 90 percent (consisting of channers, flagstones, and stones)
Calcium carbonate equivalent: 3 to 15 percent
Gypsum: 0 to 1 percent

COMPETING SERIES: Current competitors are the Pintwater, Singatse, and Sojur series. Competitors prior to the Eighth Edition, 1998 Keys to Soil Taxonomy are the Berzatic, Blacktop, and Tsaya series.
Berzatic, Blacktop, Pintwater, Sojur, and Tsaya: have soil moisture control sections that are affected by a xeric precipitation pattern and have mean annual soil temperatures greater than 50 degrees F.
GEOGRAPHIC SETTING:
Parent material: slope alluvium and colluvium over residuum derived from sandstone and shale
Landform: hillslopes
Slopes: 2 to 50 percent
Elevation: 4,700 to 6,600 feet
Mean annual air temperature: 45 to 47 degrees F.
Mean annual precipitation: 5 to 8 inches.
Frost-free period: 110 to 125 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ioka, Casmos, Gilston, Muff, and Walknolls series.
Ioka soils have bedrock at greater than 20 inches in depth and are sandy-skeletal.
Casmos soils have less than 35 percent rocks fragments in the particle-size control section.
Gilston soils occur on alluvial fans and toeslopes, are deeper than 20 inches, and have less than 35 percent rocks in the particle-size control section.
Muff soils occur on fan remnants, are deep than 20 inches, and have less than 35 percent rocks in the particle-size control section, and has a natric horizon.
Walknolls soils have a calcic horizon.
DRAINAGE AND PERMEABILITY: Well drained, high runoff, moderate permeability.
USE AND VEGETATION: These soils are used principally for rangeland, wildlife habitat, and recreation. Potential native vegetation consists of black sagebrush, shadscale, Utah greasebush, and bottlebrush squirreltail. These soils are correlated to Desert Shallow Loam (Black Sagebrush) - 034XY118UT, Desert Shallow Loam (Shadscale) - 034XY121UT, and Desert Shaly Shallow Loam (Utah Greasebush) - 034XY131UT range sites in Utah.
DISTRIBUTION AND EXTENT: Northeastern Utah. LRR D, MLRA 34. This series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana
SERIES ESTABLISHED: Uintah County, Uintah Area Soil Survey, Utah. 1998. The name is coined.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Particle-size control section: The zone from 10 to 15 inches. (Bk horizon)
Ochric epipedon: The zone from 0 to 2 inches. (A horizon)
Secondary calcium carbonate: The zone from 2 to 15 inches. (Bk horizon)
Lithic contact: The contact with sandstone bedrock at 15 inches. (R layer)
The cation exchange activity class was inferred from laboratory data from similar soils in the Uintah Area Soil Survey.
The surface texture modifier was determined following the guidelines outlined in the Utah document, "Procedures for Distributing Rock Fragments on the Surface Layer into the Upper 6 inches of Soil and Subsequent Naming of Map Units, April 1979."
