These soils have cracks at least 0.5cm wide that extend from below 20 inches to the surface during the summer in at least 6 out of 10 years. Intersecting slickensides occur between 10 and 40 inches. The A horizons haves hue of 5YR to 10YR, value of 2 to 4, and chroma of 1 to 3. Where the A horizons are less than 12 inches thick, the moist value is less than 3.5 to depths of more than 12 inches. Where chromas of 1 occur between depths of 15 inches and 20 inches, the 1 chroma material will make up less than half of the pedon.
Texture is silty clay loam, silty clay, or clay.
Reaction is slightly acid to slightly alkaline. The Bw horizons have hue of 5YR to 10YR, value of 3 to 5, and chroma of 2 to 4. Texture is silty clay or clay. Reaction ranges from slightly alkaline to moderately alkaline. Intersecting slickensides range from few to many.
