The Bt2 and Bt3 horizons have hues of 5YR through 10R, values of 3 to 5, and chroma or 4 though 8. Some pedons have chroma of 3 in most individual layers, and some are mottled in shades of brown, olive or gray in the lower part. They are silty clay or clay and their gravelly, cobbly, very gravelly or very cobbly modifiers. Some pedons are silty clay loam or gravelly silty clay loam in the upper part. The Bt4 horizons are usually mottled and are in shades of red, brown, olive, and gray, but some pedons are like the Bt2 and Bt3 horizons.
Texture is silty clay or clay and their gravelly, cobbly, very gravelly, or very cobbly modifiers.
The C or BC horizon is similar to the Bt4. These are the Maury , Shenval and Vertrees series inthe same family. Maury and Vertrees soils have a weighted average chert content of less than 15 percent in the Bt horizon. Shenval soils formed in a mantle of old alluvium and the underlying residuum from cherty limestone with a discontinuity at a depth of 24 to 40 inches. Baxter soils are on hillsides and ridgetops on the uplands.
