COMPETING SERIES: Current competitors are Avalon and Kilroy. Competitors prior to the Eighth Edition, 1998 Keys to Soil Taxonomy are Redhouse, and Minchey. All these soils are 60 inches or more deep.
GEOGRAPHIC SETTING:
Parent material: slope alluvium over residuum derived from shale interbedded with sandstone and siltstone
Landform: fan remnants and strath terraces
Slope: 2 to 8 percent
Elevation: 4,700 to 5,700 feet
Mean annual 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 Casmos, Greybull, Hiko Springs, Leeko and Walknolls soils.
Casmos and
Greybull soils are on hillslopes and do not have a calcic horizon.
Hiko Springs soils are on stream terraces and are 60 inches or more deep.
Leeko soils are on fan remnants and strath terraces and have a natric horizon.
Walknolls soils are on hillslopes and have a lithic contact within 20 inches of the surface.
DRAINAGE AND PERMEABILITY: Well drained; low and medium runoff; moderate permeability.
USE AND VEGETATION: The Pariette soils are used for irrigated cropland, rangeland, recreation, and wildlife habitat. Potential native vegetation is Indian ricegrass, galleta, globemallow, shadscale, bud sagebrush, and winterfat. This soil has been correlated to the Desert Loam (Shadscale) - 034XY106UT range site at the type location in Utah.
DISTRIBUTION AND EXTENT: The Pariette soils are small in extent and are in northeastern Utah. LLR D; MLRA 34
