GEOGRAPHIC SETTING: Fisherhill soils are on hillslopes and benches at elevations of 800 to 2,800 feet. Slopes are 2 to 65 percent. These soils formed in slope alluvium from loess. Summers are warm and dry and winters are cool and moist. The mean annual precipitation is 12 to 15 inches. The average January temperature is 33 degrees F. and average July temperature is 63 degrees F. The mean annual temperature is 49 to 52 degrees F. The frost-free season is 150 to 170 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Lickskillet, Stacker and Walla Walla soils. Lickskillet soils are on uplands, are shallow and have more than 35 percent rock fragments in the particle-size control section. Stacker soils are on side slopes, footslopes and benches and are moderately deep. Walla Walla soils are on terraces and are coarse-silty.
DRAINAGE AND PERMEABILITY: Well drained; slow to very rapid runoff; moderately slow permeability.
USE AND VEGETATION: These soils are used mainly for livestock grazing, crop production, and wildlife habitat. Native vegetation is mainly bluebunch wheatgrass, Idaho fescue, yarrow, and fiddleneck.
DISTRIBUTION AND EXTENT: Klickitat County, Washington; MLRA 8. The series is of moderate extent.
