Coarse fragments of caliche or igneous material typically range from about 35 to 65 percent. Some pedons have very thin surface layers that contain less coarse fragments. Secondary carbonates in the lower part consist of masses or concretions and range from 2 to 15 percent by volume. The Bkm horizon has hue of 5YR to 10YR, value of 8, and chroma of 1 to 3. The BCk horizon has hue of 5YR to 10YR, value of 7 or 8, and chroma of 1 to 3.
Texture is very gravelly, extremely gravelly or cobbly loamy calcareous material.
There are no competing series. Similar soils are the Amistad , Cho , Eola , Espy , Kimbrough , Mereta , Noelke , Olmos , and Tencee series. Amistad and Eola soils have carbonatic mineralogy and are underlain by limestone. Cho, Espy, and Kimbrough soils contain less than 35 percent coarse fragments. Mereta soils contain more than 35 percent clay.
