The depth to the base of soil development ranges from 38 to 60 inches. The mollic epipedon ranges from 24 to 36 inches in thickness and includes the upper part of the Bg horizon in most pedons. The particle-size control section averages between 35 and 45 percent clay and less than 10 percent fine sand or coarser. The grade of structure commonly is moderate or strong in some or all subhorizons in the subsoil. It is silty clay loam.
Reaction is moderately acid to slightly alkaline.
The AB or BA horizon, where present, has the same range of colors and reaction as the Ap or A horizon. Redoximorphic features occur in some pedons. It is silty clay loam or silty clay, except the lower part is silt loam in some pedons. Reaction ranges from slightly acid to slightly alkaline. Some pedons contain carbonates in the lower part.
