Permeability is moderate and slopes range from 1 to 60 percent. Broad soils have a soil temperature that ranges from 44 to 46 degrees F, and have a calcic horizon at 23 to 36 inches. Drage soils have less than 15 percent calcium carbonates and are very deep. Searla soils are greater than 40 inches deep, and contain 60 to 80 percent coarse fragments in the argillic. Sheep Creek soils have very cobbly B2t horizons and are underlain by limestone.
Coarse fragments are limestone or calcareous sandstone.
Bt horizons and lack Btk horizons. The Custco and Swampydraw soils are greater than 40 inches to bedrock and more than 5 inches to lime. Small soils are on nearly level to undulating mountain slopes at elevations of 5,500 to 6,600 feet. Slopes range from 1 to 60 percent. Small soils formed in rhyolite, influenced by slope alluvium and loess from mixed sources.
