Amplitude of the boundary, between the mollic epipedon and the lower horizons, ranges from about 20 to 40 inches. When dry, these soils have cracks 0.4 inches to about 3 inches wide that extent from the surface or from the base of an Ap horizon to 60 inches or more. The soils are calcareous, except for the A horizon which is noncalcareous in the micro-lows to a depth of 18 inches in some pedons that are not cultivated. The A horizon has hue of 10YR, value of 2 to 4, and chroma of 1. Texture is clay or silty clay.
Reaction is slightly alkaline or moderately alkaline.
The Bss horizon has hue of 10YR, value, of 2 to 4, and chroma of 1 or 2. Texture is clay or silty clay. Reaction is moderately alkaline. The Bssky and Bky horizons have hue of 10YR, value of 5 or 6, and chroma 1 to 3. Texture is clay or silty clay.
