Texture is clay, silty clay, clay loam, or silty clay loam with clay content of 27 to 42 percent. Rock fragment content ranges from 1 to 10 percent. Reaction ranges from slightly acid to slightly alkaline. The 2Cd or 2Cdg horizon has color and texture similar to the 2B horizon. Rock fragment content ranges from 1 to 10 percent.
Reaction is slightly alkaline or moderately alkaline.
The calcium carbonate equivalent ranges from 18 to 30 percent. These are the Angola , Baugo , Burdett , Crosier , Darien , Lamberjack , Ovid , and Shebeon series. Angola soils have a lithic contact within 40 inches. Baugo, Crosier and Shebeon soils have less than 27 percent clay in the lower part of the series control section. Burdett soils have more than 10 percent rock fragments in the lower part of the series control section.
