TYPE LOCATION: Uintah County, Utah; about 1.2 miles west of Whiterocks; located about 2,300 feet south and 300 feet east of the northwest corner of sec. 24, T. 1 N., R. 1 W., USBM; Whiterocks, Utah USGS quad; lat. 40 degrees 27 minutes 36 seconds N. and long. 109 degrees 57 minutes 9 seconds W., NAD 027
RANGE IN CHARACTERISTICS:
Soil moisture: The soil moisture control section (smcs) is usually moist. The smcs is affected by precipitation that falls evenly throughout the year, with a slight increase in the late summer and early fall.
Mean annual soil temperature: 44 to 47 degrees F.
Mean annual summer soil temperature: 67 to 70 degrees F.
Depth to endosaturation: 1.5 to 3.5 feet during the months of March to July
Depth to redox concentrations: 0 to 6 inches
Depth to lithologic discontinuity: 6 to 16 inches horizons with greater than 35 percent rock fragments
Particle-size control section: 0 to 10 percent clay; 50 to 80 percent subrounded and rounded gravel, cobbles and stones from quartzite and sandstone.
A horizon:
Hue: 7.5YR or 10YR
Value: 4 or 5 dry, 2 or 3 moist
Chroma: 2 to 4; the combination of color and thickness makes an ochric epipedon
Rock fragments: 0 to 15 percent gravel, cobbles and stones
Calcium carbonate equivalent: 0 to 5 percent
Reaction: neutral to moderately alkaline
C horizon:
Hue: 7.5YR or 10YR
Value: 4 to 6 dry, 4 or 5 moist
Chroma: 3 to 6 dry, 3 or 4 moist
Rock fragments: 0 to 15 percent gravel, cobbles and stones
Calcium carbonate equivalent: 0 to 5 percent
2AB horizon:
Hue: 5YR or 7.5YR
Value: 4 or 5 dry, 3 or 4 moist
Chroma: 2 to 4 dry or moist
Rock fragments: 35 to 60 percent gravel, cobbles and stones
Calcium carbonate equivalent: 0 to 5 percent
Reaction: neutral to moderately alkaline
2Cb horizon:
Hue: 5YR, or 7.5YR
Value: 4 to 7 dry, 4 to 6 moist
Chroma: 3 or 4 dry
Texture: extremely cobbly sand and extremely cobbly loamy sand
Rock fragments: 60 to 80 percent gravel, cobbles and stones
Calcium carbonate equivalent: 0 to 5 percent
Reaction: neutral to moderately alkaline
COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING:
Parent material: alluvium derived from sedimentary and quartzite rocks
Landform: flood plain
Slopes: 1 to 3 percent
Elevation: 5,900 to 6,300 feet
Mean annual air temperature: 42 to 45 degrees F.
Mean annual precipitation: 10 to 12 inches
Frost-free period: 90 to 110 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Moynier and Wonsits series.
Moynier soils occur on flood plains, are very poorly drained and have fine-loamy particle-size control sections.
Wonsits soils occur on flood plains and have mollic epipedons 16 to 24 inches thick.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained, very low runoff, rapid permeability. These soils are occasionally flooded for very long periods during the months of March to July.
USE AND VEGETATION: The main uses are wildlife habitat, woodland grazing and recreation. The potential native plant community is ponderosa pine with an understory of baltic rush, needleandthread, sagebrush, skunkbush sumac and silverberry. These soils have been correlated to Semimoist Stream Terrace (Ponderosa Pine) - 047CY007UT range site in Utah.
DISTRIBUTION AND EXTENT: Northeastern. LRR E, MLRA 047. 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 comes from a geographic feature in the survey area.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Particle-size control section: The zone from 10 to 40 inches. (C, 2Ab, and 2C1b horizons)
Ochric epipedon: The zone from 0 to 7 inches. (A1 and A2 horizons)
Redoximorphic concentration: The presence of redox concentrations in the zone from 2 to 14 inches. (A2 and C horizons)
Endosaturation: The presence of a saturated zone from 1.5 to 3.5 feet during the month of March to July.
Lithologic discontinuity: At the upper boundary of the 2Ab horizon.
The siliceous mineralogy was inferred from laboratory data in the Uintah Area Soil Survey.
