GEOGRAPHIC SETTING: Goldendale soils are on plateaus, ridgetops, footslopes and backslopes at elevations of 800 to 3,500 feet. Slopes are 2 to 65 percent. They formed in alluvium, loess and residuum from basalt, with minor amounts of volcanic ash. Summers are warm and dry, winters are cool and moist. The mean annual precipitation is 15 to 18 inches. The average January temperature is 29 degrees F. and the average July temperature is 67 degrees F. The mean annual temperature is 47 to 50 degrees F. The frost-free season is 90 to 150 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Blockhouse, Gunn, Konert, and Lorena soils. Blockhouse soils are on alluvial plains, have a mollic epipedon more than 20 inches thick and are moderately well drained. Gunn soils are on plateaus and side slopes and lack a mollic epipedon. Konert soils are on flood plains, have an aquic moisture regime and have more than 35 percent clay in the argillic horizon. Lorena soils are on plateaus and side slopes and have a lithic contact at a depth of 20 to 40 inches.
DRAINAGE AND PERMEABILITY: Well drained; slow to medium runoff; moderate permeability.
USE AND VEGETATION: These soils are used mainly for cropland. Small grains, hay and pasture are principal crops. It is also is used for limited livestock grazing. Native vegetation is Oregon white oak, antelope bitterbrush, bluebunch wheatgrass, Idaho fescue, Sandberg bluegrass and eriogonum.
DISTRIBUTION AND EXTENT: Klickitat County, Washington; MLRA 8. The series is moderately extensive.
