REMARKS: Diagnostic horizons and features recognized in this pedon are:
Umbric epipedon - the zone from the surface to a depth of 16 inches. (the Ap and A horizons)
Argillic horizon - the zone between 16 and 45 inches. (Btg1, Btg2, and Btg3 horizons)
Aquic conditions - colors with chroma of 2 or less below the surface layer caused by saturation.
