These are the Kingtain , Pheeney , Sheld , Tumac and Waca series. Kingtain soils are dry in the centrol section for 45 to 60 consecutive days each year. Sheld soils have buried Bt horizons. Tumac soils have greater than 60 percent volcanic ash in the upper 13 inches of the soil. Pheeney and Waca soils are less than 40 inches to bedrock.
Washougal soils have mesic temperature regimes.
Windy soils are on mountains and plateaus in the Sierra Nevada and Cascade Range of northern California. They formed in material weathered from volcanic mud flow, primarily of andesite but including dacite or basalt in some areas. Elevation ranges from 4,000 to 9,000 feet and annual precipitation ranges from 40 to 80 inches, mostly as winter snow. Slopes are 5 to 75 percent. The average frost-free period is 30 to 60 days.
