Most pedons are noneffervescent. The Bk or 2Bkb horizon, where present, has hue of 2.5YR or 5YR, value of 4 or 5, and chroma of 4 or 6. Texture is loam, sandy clay loam, silty clay loam or clay loam. Clay content ranges from 18 to 38 percent. Calcium carbonate occurs as masses or concretions.
Reaction is moderately alkaline and is strongly effervescent.
The BC, BCk, or 2BCkb horizon, where present, have color, texture, and reaction similar to the Bk or 2Bkb horizon. These are the Braman , Corbin , Irene , Pond Creek , St. Paul, and Westview series. Corbin and Pond Creek soils are on uplands. Corbin soils have hues of 7.5YR or 10YR in the argillic horizon, and over 35 percent clay in the lower argillic horizon. Braman soils developed in Pleistocene sediments on high flood plains of major streams.
