COMPETING SERIES: There are no competing series. The following series are similar and some may qualify as Vertic; Devoy, Embargo, Home Camp, Lemco (T), Passar, Redchief, Resoot (T), Rooset, Spinlin, Tatiyee, Tellura, Threedot (T), Wesdy (T), and Wilpar series. The Devoy, Embargo, and Home Camp soils have a lithic contact above 40 inches. Lemco soils have a O horizon and precipitation greater than 22 inches. Passar soils have rock fragments mainly larger than 10 inches. Redchief soils are medium to strongly acid. Resoot soils have lime below 22 inches. Rooset soils lack 10YR hues in the argillic horizon and recieve equal amounts of precipitation during most months. Tatiyee soils have ustic soil moisture regimes. Tellura soils have lime below 40 inches. Threedot soils have E horizons. Wesdy (T) have a udic soil moisture regime. Spinlin soils have highly weathered bedrock above 40 inches. Wilpar soils have a mean annual soil temperature of 44 to 47 degrees F.
GEOGRAPHIC SETTING: Frymire soils are on foothills and mountainsides at elevations of 6,000 to 8,000 feet. Slopes range from 15 to 50 percent. The soils formed in colluvium and alluvium from challis volcanics. The average annual precipitation ranges from 14 to 16 inches. The average annual air temperature is about 38 to 40 degrees F. The frost free season is 50 to 60 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cronks, Howcan, Hutchley, and Riverlost soils. Cronks, Howcan, Hutchley, and Riverlost soils all have a frigid temperature regime. Hutchley soils are shallow to bedrock. Cronks and Riverlost have calcic horizons.
DRAINAGE AND PERMEABILITY: Well drained; medium to very high runoff and slow permeability.
USE AND VEGETATION: Used primarily for range and wildlife habitat. Vegetation is mainly mountain big sagebrush and bluebunch wheatgrass.
DISTRIBUTION AND EXTENT: Southeast Idaho. These soils are of small extensive.
