TYPE LOCATION: Uintah County, Utah; about 1.5 miles southeast of Ruple Point on Blue Mountain; located about 2,400 feet east and 2,500 feet south of the northwest corner of sec. 19, T.4S., R.25E., SLBM; Split Mountain, Utah USGS quad; lat. 40 degrees 27 minutes 31 seconds N. and long. 109 degrees 8 minutes 43 seconds W., NAD 27
RANGE IN CHARACTERISTICS:
Soil moisture: The soil moisture control section is affected by precipitation that falls evenly through the year with a slight increase in late summer and early fall. Typic Ustic moisture regime.
Mean annual soil temperature: 42 to 45 degrees F.
Depth to paralithic contact: 40 to 60 inches to weathered shale or sandstone
Thickness of the mollic epipedon: 10 to 16 inches
Surface rock fragments: 25 to 50 percent (predominantly flagstones and channers with smaller amounts of stones and boulders derived from sandstone and shale lithology).
Particle-size control section: 7 to 18 percent clay; 35 to 70 percent rocks (predominantly flagstones and channers derived from sandstone and shale lithology).
A horizon:
Hue: 5YR to 10YR
Value: 3 or 4 dry, 2 or 3 moist
Chroma: 2 or 3
Calcium carbonate equivalent: 1 to 10 percent
Reaction: slightly alkaline or moderately alkaline
C horizon:
Hue: 5YR to 10YR
Value: 4 to 6 dry, 3 to 5 moist
Chroma: 4 to 6
Texture: fine sandy loam, loam, sandy loam with very flaggy or extremely flaggy modifiers
Calcium carbonate equivalent: 1 to 10 percent
Reaction: slightly alkaline or moderately alkaline
COMPETING SERIES: These are the Perma and Wimper series.
Perma and Wimper soils do not have a paralithic or lithic contact within 60 inches of the surface.
GEOGRAPHIC SETTING:
Parent material: colluvium derived from sandstone and shale.
Landform: hillslopes.
Slopes: 50 to 80 percent
Elevation: 6,200 to 7,800 feet
Mean annual air temperature: 40 to 43 degrees F.
Mean annual precipitation: 16 to 22 inches.
Frost-free period: 70 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cortyzack, Duffymont, Sheecal, and Splimo series.
Cortyzack soils occur on hill summits and shoulders and are very deep.
Duffymont soils occur on hill summits and shoulders and are shallow to bedrock.
Sheecal soils occur on hillslopes and do not have a mollic epipedon.
Splimo soils occur on hillslopes and are shallow to bedrock.
DRAINAGE AND PERMEABILITY: Well drained, medium runoff, moderately rapid permeability.
USE AND VEGETATION: The major uses are rangeland, wildlife habitat, and recreation. These soils have been correlated to Mountain Very Steep Stony Loam (Browse) - 047CY474UT range sites in Utah.
DISTRIBUTION AND EXTENT: Northeastern Utah. LRR E, MLRA 47. This series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana
SERIES ESTABLISHED: Uintah County, Uintah Area Soil Survey, Utah. 1998. The name is taken from a nearby geographic location.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Particle-size control section: The zone from 10 to 40 inches. (A2, C1, and C2 horizons)
Mollic epipedon: The zone from 0 to 15 inches. (A1 and A2 horizons)
Paralithic contact: The contact with weathered sandstone at 58 inches. (Cr horizon)
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."
