Reaction is moderately acid to moderately alkaline, but some pedons are strongly acid in the lower part of the Bw and C horizon. Some pedons have buried A or B horizons below a depth of 20 inches. The Ap horizon has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 2 or 3. Texture is loam, silt loam, or silty clay loam. The Bw horizon has hue of 7.5YR to 2.5Y, value of 4 or 5, and chroma of 3 to 6.
Texture is silt loam or silty clay loam.
The C horizon has hue of 7.5YR to 2.5Y, value of 4 or 5, and chroma of 2 to 6. Texture is silty clay loam, silt loam, loam, fine sandy loam, or sandy loam, the range also includes stratified layers of these or their gravelly or cobbly analogs. These are Jamesfin , Kinnick , Moshannon , and Ray series in the same family. Jamesfin soils are close competitors and better differentiation is needed between these two series. Kinnick soils have redox depletions indicative of a seasonal water table between depths of 3 to 6 feet.
