Guernsey and Sees soils have mottles with chroma of 2 or less within a depth of 10 inches below the top of the argillic horizon. Muse soils have less than 35 percent base saturation. Woolper soils have a mollic epipedon. Brookside soils are on foot slopes, fans, and benches. Slopes range from 3 to 60 percent.
Landslips are common in many areas as are small seepy areas and springs.
These soils formed in clayey colluvium mainly from interbedded acid and some calcareous gray shale, siltstone, limestone, and sandstone which has been mixed by downslope movement. The colluvium is commonly 6 to 20 feet thick. Brooke soils are on ridge crests or on saddles between ridges and are underlain by fractured limestone at depths of 20 to 40 inches. Culleoka soils are on narrow summits and shoulder slopes where fine-grained sandstone bedrock is at a depth of 20 to 40 inches. Elba soils are on side slopes and benches formed in clayey residuum from limestone shale and siltstone and have free carbonates at depths of 10 to 30 inches.
