Brequito soils have less than 5 percent cobbles in the argillic horizon. Scaler soils have 30 to 85 percent mica in the 3Bt and 3C horizons. Riswold soils are on canyon sides, hills, plateaus, and benches at elevations of 1,600 to 3,500 feet with slopes of 5 to 70 percent. These soils formed in volcanic ash and loess over material weathered from basalt. The Elkridge soils are loamy-skeletal and are on convex positions.
Grangemont soils contain fragic material and are on concave positions on plateaus.
