TYPE LOCATION: Yakima County, Washington, 1,600 feet west, 800 feet north of southeast corner, section 7, T. 14 N., R. 23 E.; USGS Priest Rapids topographic quadrangle; Lat. 46 degrees 42' 36" W. and Long. 119 degrees 59' 07" W.
RANGE IN CHARACTERISTICS: The average annual soil temperature at depth of 20 inches ranges from 50 to 55 degrees F. These soils are usually dry in the soil moisture control section. The particle-size control section averages 15 to 27 percent clay in the fine earth fraction and 35 to 60 percent coarse fragments by volume. Organic matter is estimated to range from 0.5 to 1 percent. Solum thickness and depth to a lithic contact ranges from 20 to 40 inches.
The A horizon has value of 3 or 4 moist. It is neutral or slightly alkaline.
The BA horizon is very gravelly loam or very cobbly loam.
The Bt horizons have chroma of 3 or 4 dry or moist. They are very gravelly loam or very gravelly loam. They are neutral or slightly alkaline.
The Bk horizons have a value of 5 or 6 dry, 3 or 4 moist and chroma of 3 or 4, dry or moist. They are extremely cobbly loam, very gravelly loam, or extremely gravelly loam. They are slightly or moderately alkaline.
COMPETING SERIES: These are the Bairs (T), Breko, Cowgil, Daint (T), Hefed, Hunewill, Jungo, Lithgow, Plush, Stucky and Washoe. Bairs soils have stones and boulders in the profile. Breko soils have a mean annual soil temperature of more than 55 degrees F. Cowgil, Daint, Plush, Stucky and Washoe soils are more than 40 inches deep. Hefed soils have sandy loam or loamy sand textures with 40 to 60 percent rock fragments below the Bt horizon. Hunewill soils have extremely gravelly or cobbly sand below the Bt horizon. Jungo soils are very deep and have secondary carbonates 4 to 8 inches below the surface. Lithgow soils have a Bt horizon with 27 to 35 percent clay.
GEOGRAPHIC SETTING: Drino soils are on hillslopes and have slopes of 15 to 75 percent. These soils formed in loess and colluvium from basalt. Elevations are 500 to 2,000 feet. These soils occur in an arid climate with hot, dry summers and cool, moist winters. The average annual precipitation ranges from 6 to 9 inches. The average annual temperature is about 50 degrees F. The average January temperature is about 29 degrees F.; the average July temperature is about 71 degrees F. The frost-free season is 135 to 195 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Disage, Fortyday, Kiona, Nevo, and Sohappy series. Disage soils are on ridge tops and hillslopes, are clayey-skeletal and 12 to 20 inches to a lithic contact. Fortyday soils are on ridges and plateau sideslopes and are 14 to 20 inches to a lithic contact. Kiona soils are on hillslopes and colluvial sideslopes and are greater than 40 inches to a lithic contact. Nevo soils are on hillslopes, ridgetops and benches and are 5 to 12 inches to a lithic contact. Sohappy soils are on benches and toeslopes and are coarse-loamy and greater than 40 inches to a lithic contact.
DRAINAGE AND PERMEABILITY: Well drained; runoff is medium to very rapid; moderate permeability.
USE AND VEGETATION: Rangeland and wildlife. Native vegetation is bluebunch wheatgrass, stiff sagebrush, Sandberg bluegrass, arrowleaf balsamroot, Wyoming big sagebrush, rock eriogonum, and spiny hopsage.
DISTRIBUTION AND EXTENT: Yakima and Kittitas Counties, Washington. Series is of small extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are an ochric epipedon from the surface to 7 inches, an argillic horizon from 7 to 19 inches and a lithic contact at 38 inches. The particle-size control section is the zone from 7 to 19 inches (argillic horizon). This soil is reclassified based on amendment 17 of Soil Taxonomy.
