The A horizon has colors in shades of brown or gray, hue of 10YR or 2.5Y, value of 3 to 5, and chroma of 1 to 3. Colors with chroma of 2 or less in the subsoil are considered to be litho-chromic. Mottles with chroma of 3 or more, or redox concentrations, are considered to be relic or litho-chromic. Mottles in shades of brown and yellow range from none to common. When matrix values are less than 3.5, thickness of the A horizon is less than 12 inches thick.
Texture is clay or clay loam.
The B horizons have colors in shades of brown and yellow hue of 7.5YR to 5Y, value of 4 to 7, and chroma of 2 to 8. Mottles range from few to many in shades of gray, brown, yellow, and olive. Reddish mottles range from few to many and occur in the upper B horizons, typically above the layers containing concretions or masses of calcium carbonate. Pitted concretions and threads or pockets of soft calcium carbonate range from 0 to 15 percent in the upper B horizons and from 3 to 20 percent in the lower B horizons. Some pedons have calcic horizons.
