TYPE LOCATION: Kittitas County, Washington, about 3.5 miles southwest of Vantage, WA, about 3,100 feet east and 850 feet north of the southwest corner of section 28, T. 17 N., R. 22 E.; USGS Ginkgo topographic quadrangle; lat. 46 degrees 55 minutes 48 seconds N. and long. 120 degrees 04 minutes 42 seconds W.
RANGE IN CHARACTERISTICS: The average annual soil temperature at the lithic contact ranges from 50 to 56 degrees F. These soils are dry in all parts of the moisture control section more than half of the time. The particle-size control section averages 35 to 42 percent clay in the fine earth fraction and 35 to 50 percent coarse fragments by volume. Organic matter is estimated to range from 0.5 to 1 percent. Solum thickness and depth to bedrock ranges from 20 to 40 inches.
The A horizon has a value of 4 or 5 dry, and a chroma of 2 or 3 moist.
The Bt horizons have value of 4 or 5 dry, and chroma of 2 or 3 moist. They are gravelly clay loam or very gravelly clay loam. They are neutral or slightly alkaline.
The 2Btk and 3Btk horizons have hue of 10YR or 7.5YR, chroma of 2 through 4 dry or moist. They are very gravelly clay, extremely cobbly clay, or extremely gravelly clay. Structure is moderate to strong subangular blocky, angular blocky or prismatic. They are slightly or moderately alkaline.
COMPETING SERIES: These are the Berning, Bilbo, Havingdon, Lizzysprings (T), Maderbak, Pula, Pulcan, Surgem, Tenmile, Vanwyper and Zephan series. Berning, Bilbo, Lizzysprings, Pula and Tenmile soils are more than 40 inches to bedrock. Havingdon soils have clay films along fracture planes of chert bedrock and have 50 to 80 percent pebbles of dominantly angular chert and shale in the particle-size control section. Maderbak soils lack fractured basalt with silica coatings and lack a lithologic discontinuity in the argillic horizon. Pulcan and Zephan soils have a paralithic contact within 40 inches. Surgem and Vanwyper soils lack accumulations of secondary lime at the lithic contact and lack a lithologic discontinuity in the argillic horizon.
GEOGRAPHIC SETTING: Clenage soils are on ridgetops and hill slopes and have slopes of 15 to 30 percent. These soils formed in interbedded sediments, residuum and colluvium from basalt and some loess. Elevations are 600 to 2,000 feet. These soils are in an arid climate with hot dry summers and cool moist winters. The average annual precipitation ranges from 6 to 9 inches. The average January temperature is about 29 degrees F.; the average July temperature is about 50 degrees F.; and the average annual temperature is about 49 to 51 degrees F. The frost-free season is 135 to 195 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Fortyday, Drino, Kiona, Nevo, and Sohappy series. Drino soils are on hillslopes and are 20 to 40 inches to bedrock. Fortyday soils are on ridges and plateau sideslopes and are 12 to 20 inches to a lithic contact. Kiona soils are on hillslopes and colluvial sideslopes and are more than 40 inches deep. 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 more than 40 inches deep.
DRAINAGE AND PERMEABILITY: Well drained, medium to rapid runoff; slow permeability.
USE AND VEGETATION: Used for livestock grazing and wildlife habitat. Native vegetation is bluebunch wheatgrass, Sandburg bluegrass and Wyoming big sagebrush.
DISTRIBUTION AND EXTENT: Yakima and Kittitas Counties, Washington. Series is of small extent.
