TYPE LOCATION: Douglas County, Washington; near center section 5, T. 23 N., R. 22 E.
RANGE IN CHARACTERISTICS: The mean annual soil temperature is 47 to 51 degrees F. These soils are usually moist, but are dry in all parts between depths of 8 and 25 inches for 90 to 105 consecutive days. Depth to bedrock is 40 to more than 60 inches. The particle-size control section contains 35 to 90 percent rock fragments. The mollic epipedon is 10 to 20 inches thick
.
The A horizon has hue of 10YR or 7.5YR, a value of 4 or 5 dry, 2 or 3 moist and chroma of 2 or 3 dry or most. Soil reaction is neutral or slightly alkaline. Texture is very cobbly silt loam or very stony silt loam.
The Bt horizon has hue of 7.5YR or 10YR, dry value of 4 through 6 and chroma of 2 through 4 moist or dry. It is very gravelly extremely gravelly, very cobbly, extremely cobbly, or very stony. The fine-earth fraction is clay loam, silty clay loam, loam or silt loam with 18 to 35 percent clay. Soil reaction is neutral or slightly alkaline. The lower Bt horizon is very stony in some pedons.
The C horizon has hue of 2.5Y, 10YR, or 7.5YR, value of 4 through 6 dry, 3 through 5 moist and chroma of 2 through 4 moist or dry. Texture is loam, silt loam or clay loam in the fine-earth fraction and has 35 to 70 percent rock fragments. Clay content is 20 to 28 percent. It has white mycelial lime in some pedons. Some gravel and cobbles in the C horizon have white lime-silica coatings on the underside. Soil reaction is slightly alkaline or moderately alkaline.

GEOGRAPHIC SETTING: These soils are on hills, mountains, and canyon walls and sideslopes at elevations of 1,500 to 4,000 feet. Elevations in Idaho range from 4,000 to 5,500 feet. They formed in mixed loess and colluvium. Slope ranges from 3 to 70 percent. Summers are warm and dry, and winters are cool and moist. The mean annual precipitation is 12 to 18 inches. The average January temperature is 25 degrees F. and the average July temperature is 70 degrees F. The mean annual temperature is about 49 degrees F. The frost-free season is 110 to 165 days in Washington and 85 to 110 days in Idaho.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bagdad, Cheviot, Condon, Cordy, Ralls, Rock Creek, Tronsen and Timentwa soils. Bagdad soils are on uplands and hills and lack rock fragments. Cheviot soils are on footslopes and sideslopes and lack an argillic horizon. Condon soils are on uplands and are 20 to 40 inches deep to basalt. Cordy soils are on mountains and are frigid. Ralls soils are on hillsides and are coarse-loamy and have an aridic moisture regime. Rock Creek soils are on ridgetops and plateaus and have a clayey argillic horizon and are 8 to 20 inches deep to basalt. Tronsen soils are on benches and ridgetops and have greater than 35 percent clay in the particle- size control section. Timentwa soils are on uplands and are ashy over loamy and have a mollic epipedon more than 20 inches thick.
DRAINAGE AND PERMEABILITY: Well drained; slow to very rapid runoff; moderately slow permeability.
USE AND VEGETATION: These soils are used for domestic livestock grazing. Vegetation is mainly Sandberg bluegrass, bluebunch wheatgrass, Idaho fescue, and Wyoming big sagebrush.
