COMPETING SERIES: Current competitors are the Geer, Shotnick and Wentridge series. Competitors prior to the Seventh Edition, 1996 Keys to Soil Taxonomy are the Apron, Fang, Fruitland, Ganaflan, Jeddito, Kumiva, Marcou, Mazuma, Moepitz, Piltdown, Sodaspring, Tooele, Trachute, Vanderhoff, and Worland series.
Apron soils have hue yellower than 10YR in the substratum.
Fang, Geer, and Kumiva: have pyroclastic materials in particle-size control section, and have xeric moisture patterns.
Fruitland soils have soil temperatures greater than 51 degrees F, and have soil moisture control sections that are affected by peaks precipitation during December through March and July through September, and are driest during May and June.
Ganaflan, Mazuma, Piltdown, and Tooele: have xeric moisture patterns.
Jeddito: and have soil moisture control sections that are affected by peaks precipitation during December through March and July through September, and are driest during May and June.
Marcou: has hue redder than 7.5YR.
Moepitz, Vanderhoff, Wentridge, and Worland: have bedrock within 40 inches.
Shotnick: have SARs less than 5.
Sodaspring soils have greater than 15 percent gravel in the particle-size control section.
Trachute soils have accumulations of secondary gypsum and calcium carbonate.
GEOGRAPHIC SETTING:
Parent material: alluvium derived from sedimentary rocks
Landform: alluvial flats
Slopes: 0 to 2 percent

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Eghelm, Green River, and Motto series.
Eghelm soils occur on flood plains, are rarely flooded, and have sandy substratum.
Green River soils occur on flood plains and have a seasonal high water table at a depth of 40 to 60 inches.
Motto soils are on hillslopes and have a lithic contact within 20 inches of the surface.
DRAINAGE AND PERMEABILITY: Well drained, low runoff, moderate permeability.
USE AND VEGETATION: Used for livestock grazing, wildlife habitat, and recreation. Potential native plant community is black greasewood, bottlebrush squirreltail, alkali sacaton, shadscale, and Indian ricegrass. This soil has been correlated to the Alkali Flat (Black Greasewood) - 034XY006UT range site at the type location .
