Total rock fragment content is 5 to 30 percent. It is mildly or moderately alkaline . The 2Crkq horizon is paralithic tuff of the Deschutes Formation. This horizon is absent in some pedons. Capona soils are slightly acid or neutral and lack the volcanic glass in the surface.
Lovline soils are channery throughout and are moderately deep over schist.
Quencheroo soils are greater than 40 inches to bedrock. Sutro soils have a paralithic contact at 20 to 40 inches and lack the lithic contact. Agency soils are on terraces and plateaus. Slopes are o to 70 percent but are typically less than 15 percent. These soils formed in medium textured eolian materials and are underlain by tuff, basalt, or other components of the Deschutes Formation.
