The soils have cracks from 0.5 to 2 inches wide and 12 inches or more long that extend from the surface or the lower boundary of the Ap horizon to depths of 30 to more than 40 inches and are open most of the time if the soil is not irrigated. The soil ranges from calcareous to noncalcareous in the upper 12 inches, and is calcareous below this depth. Some pedons have calcic horizons below 40 inches. The A horizon has hue of 5YR to 10YR, value of 4 or 5, and chroma of 2 to 4. More than half of each pedon, to a depth of 12 or more inches, has chroma of less than 3 moist or dry.
Texture is clay, clay loam, silty clay, or their cobbly or very cobbly counterparts.
Clay content ranges from 35 to 60 percent. Coarse fragments range from 0 to 65 percent of which 0 to 25 percent are gravel, and 0 to 45 percent cobbles. Some pedons are slightly effervescent.
