COMPETING SERIES: These are the
Crib and
Lind series.
Crib soils have lithologic discontinuities with skeletal layers below 40 inches and have total(silicate + carbonate) clay.greater than 18 percent.
Lind soils have greater than 18 percent total (silicate + carbonate) clay.
GEOGRAPHIC SETTING:
Parent material: eolian material over alluvium derived from sandstone, shale, limestone and quartzite
Landform: fan remnants
Slopes: 0 to 2 percent
Elevation: 4,700 to 5,300 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 Nakoy and Shotnick series.
Nakoy soils occur on fan remnants and are well drained
Shotnick soils occur on alluvial flats and do not have calcic horizons
DRAINAGE AND PERMEABILITY: somewhat poorly drained, very low runoff, moderately rapid permeability.
USE AND VEGETATION: These soils are used for irrigated cropland and pasture. Principle crops grown are alfalfa hay, grass hay, and small grains.
DISTRIBUTION AND EXTENT: Northeastern Utah. LRR D, MLRA 34. This series is of small extent.
MLRA OFFICE RESPONSIBLE: Lakewood, Colorado
SERIES ESTABLISHED: Uintah county, Utah, Uintah Area SSA, 1998. The name is coined.
