The thickness of the solum, depth to the base of the argillic horizon, and depth to the lithic contact range from 20 to 40 inches. The particle-size control section averages 35 to 45 percent clay. Rock fragments are glacial erratics, primarily of limestone, dolostone, and crystalline lithology. Texture is silty clay loam, clay loam, loam, or silt loam. Rock fragment content ranges from 0 to 14 percent.
Reaction is slightly acid or neutral.
