The C horizon has hue of 10YR to 5Y, value of 3 to 5, and chroma of 1 to 4. Texture is silt loam, loam, silty clay loam or clay loam in the fine earth fraction. Consistence is firm or very firm. Rock fragments range from 10 to 60 percent, and include 5 to 10 percent greater than 3 inches in diameter. In some pedons, rock fragments are absent below 40 inches.
Reaction ranges from slightly alkaline to moderately alkaline.
Some pedons lack carbonates in the upper part of the C horizon. These are the Angola , Burdett , Crosier , Haskins , Lamberjack , and Ovid series. Angola soils have bedrock at depths of less than 40 inches. Burdett soils have a lithologic discontinuity at depths of 13 inches or more. Crosier and Haskins soils have a densic contact in the substratum.
