The mollic epipedon is 10 to 20 inches in thickness and extends into the AB horizon, the BA horizon, or the upper part of the Bg horizon in some pedons. Depth to carbonates ranges from 15 to 35 inches. Pedons that have carbonates at depths at the shallower end of the range are not as deep to the base of the cambic horizon and have clay content at the low end of the range. In places, carbonate concretions are on the soil surface and in the A horizon because of crayfish activity or other mixing. The particle-size control section averages between 27 and 35 percent clay and less than 5 percent fine sand or coarser.
Reaction ranges from slightly acid to slightly alkaline.
It is dominantly silty clay loam, but in some pedons it grades to silt loam in the lower part. Reaction is neutral to moderately alkaline. Calcium carbonate concretions are in the lower part in most pedons, and range from few in number to almost continuous masses in horizontal bands or irregular bodies or pockets. In some pedons the only evidence of carbonates is effervescence of the fine earth fraction. Krotovina are common throughout the B and C horizons and in places make horizon boundaries obscure.
