COMPETING SERIES: These are the Bigmon (T), Kenzo, Lazear, Rizno, Redspear, Rizozo, Skyvillage, Travson, Travessilla, and Zukan series.
Bigmon: have Cr horizons and have MAAT of 47 to 49 degrees F.
Kenzo: have soil temperatures greater than 50 degrees F.
Lazear: have more than 18 percent clay in the particle-size control section.
Redspear, Rizno, and Rizozo: have hue redder than 7.5YR.
Skyvillage: Do not have soil moisture control sections affected by an even distribution of precipitation throughout the year. The soil moisture control section is dry mid-February through June and periodically moist November to mid-February.
Travson: has dry periods in late summer and early fall and receives most of its precipitation during April, May, and June
Travessilla and Zukan: have mean annual soil temperatures greater than 50 degrees F. Zukan also has secondary calcium carbonate accumulations.
GEOGRAPHIC SETTING:
Parent material: eolian deposits and slope alluvium over residuum derived from sandstone and interbedded sedimentary rock
Landform: hillslopes, ledges, scarps and structural benches
Slopes: 2 to 50 percent
Elevation: 4,500 to 7,000 feet
Mean annual air temperature: 45 to 50 degrees F.
Mean annual precipitation: 8 to 12 inches
Precipitation pattern: Wettest months are July to October and driest months are December and June.
Frost-free period: 110 to 150 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Begay, Mespun, and Montwel series.
Begay soils are on fan remnants and are very deep.
Mespun soils are on ridges and are very deep.
Montwel soils are hillslopes and are moderately deep.
DRAINAGE AND PERMEABILITY: Well drained, low and medium runoff, moderately rapid permeability.
USE AND VEGETATION: The major uses are wildlife habitat, rangeland, and recreation. The potential native plant community is Utah juniper, black sagebrush, Indian ricegrass, galleta, and bluebunch wheatgrass. This soil has been correlated to Semidesert Shallow Loam (Utah Juniper-Pinyon) - 034XY233UT range site in Utah.
DISTRIBUTION AND EXTENT: Northeast and central 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 taken from a geographic location in the area.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Particle-size control section: The zone from the surface to 10 inches. (A and C horizons)
Ochric epipedon: The zone from 0 to 2 inches. (A horizon)
Lithic contact: The contact with unweathered sandstone bedrock at 10 inches. (R layer)
The cation exchange activity class was inferred from laboratory data from similar soils in the Uintah Area Soil Survey.
