COMPETING SERIES: These are the Appian, Biddleman, and Bighat series.
Appian, Biddleman, and Bighat soils are all very deep
GEOGRAPHIC SETTING:
Parent material: eolian deposits and slope alluvium over residuum derived from sandstone
Landform: strath terraces
Slopes: 2 to 5 percent
Elevation: 4,700 to 5,500 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 Cadrina, Minchey, Muff, and Nakoy series.
Cadrina soils occur on hillslopes and are shallow.
Minchey and Nakoy soils occur on fan remnants and are very deep.
Muff soils occur on structural benches and do not have a sandy substratum.
DRAINAGE AND PERMEABILITY: Well drained, low runoff, moderately slow permeability.
USE AND VEGETATION: The major uses are rangeland, wildlife habitat, and recreation. The potential native plant community is fourwing saltbush, shadscale, Indian ricegrass, sand dropseed, and spiny hopsage. This soil has been correlated to Desert Alkali Sand (Fourwing Saltbush) - 034XY106UT range site at the type location in Utah.
DISTRIBUTION AND EXTENT: Northeastern Utah. LRR D, MLRA 34. This series is of small extent.
