In some pedons the surface layer is slightly lighter colored because of recent overwash. It is silt loam, loam, clay loam or silty clay loam. In some areas this horizon has redox features. In some pedons this horizon is absent but the mollic epipedon is at least 24 inches thick. Some pedons have an AC horizon with color and texture similiar to the AB and Bg horizons and ranges from 0 to 15 inches thick.
Texture is silt loam, clay loam, sandy clay loam or silty clay loam.
The particle size control section averages between 28 and 35 percent clay. Some pedons contain thin strata with less than 20 percent clay or more than 35 percent clay. A sandy substratum phase is recognized that allows coarse sand and gravelly sand at depths below 40 inches. Accumulations of calcium carbonates are common below a depth of 24 inches. Where chroma of 2 is present, the soil commonly has distinct or prominent redox features in the soil matrix.
