Reaction is neutral to moderately acid. Some pedons have an E horizon with hue of 10YR or 7.5YR, value of 4 to 6 and chroma of 3 or 4. The Bt horizon has hue of 10YR or 7.5YR, value of 4 or 5 and chroma of 3 to 6. It is silty clay loam or silt loam. Some pedons have up to 10 percent chert gravel in the lower part of the Bt horizon and the Btx horizon.
Reaction is very strongly acid to moderately acid.
The Btx horizon has hue of 10YR or 7.5YR, value of 4 to 6, and chroma of 2 to 6. Reaction is strongly acid to slightly acid. Brittleness is evident in 30 to 60 percent of the mass. It is clay, silty clay, and, less commonly, silty clay loam or their gravelly or very gravelly analogues. Reaction ranges from strongly acid to slightly alkaline.
