COMPETING SERIES: These are the Waca and Windy soils. The Waca soils are moderately deep to a paralithic contact. The Windy soils are deep or very deep to a paralithic contact.
GEOGRAPHIC SETTING: The Badgerwash soils are on outwash plains in the Southern Cascade mountains. Slopes are 2 to 15 percent. These soils formed in mixed tephra and outwash over outwash from volcanic rocks. Elevation is 6200 to 6600 feet 91890 to 2012 m). The mean annual precipitation is 41 to 49 inches (1041 to 1245 mm). The mean annual temperature is 42 to 43.5 degrees F (5.7 to 6.4 degrees C). Frost free season is 60 to 85 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Badgerflat and Buttewash soils. The Badgerflat soils are moderately deep to dense till and are on moraines. The Buttewash soils are deep to a duripan, have tephra from Cinder Cone on the surface and are on outwash plains.
DRAINAGE AND PERMEABILITY: Well drained; saturated hydraulic conductivity is moderately rapid to rapid in A horizon, very rapid in the AC horizon, moderately rapid in the 2Ab and 2Bwb horizons, and slow to very slow in the 2Bqmb horizon.
USE AND VEGETATION: This soil is used for wildlife habitat, recreation, ecosystem management and watershed. Vegetation is lodgepole pine, western needlegrass, squirreltail, carex, and narrowleaf lupine.
DISTRIBUTION AND EXTENT: The soils are inextensive and are mapped in MLRA: 22B Southern Cascade Mountains
