These soils formed in slope alluvium and residual material weathered from noncalcareous sedimentary rock. Slopes range from 2 to 40 percent. Depth to soft bedrock is 20 to 40 inches. The mollic epipedon is 7 to 15 inches thick. An Oi horizon is present in some pedons.
Reaction ranges form medium acid through neutral.
The texture modified by rock fragments is sandy loam, clay loam, or loam averaging 18 to 35 percent clay and less than 35 percent fine or coarser sand. Pebbles or channers range from 0 to 35 percent. Reaction is medium acid through neutral. The texture modified by rock fragments is loam, clay loam, or sandy clay loam with 18 to 30 percent clay. Rock fragments range from 0 to 50 percent pebbles or channers and 0 to 10 percent flagstones.
