These soils formed in alluvium or colluvium and in residuum of limestone, sandstone and shale. They are on hillsides, benches and foot slopes. Slopes range from 2 to 60 percent. Solum thickness is greater than 60 inches. Depth to bedrock is 6 feet or more.
Reaction is very strongly acid or strongly acid except the surface layer is less acid where limed.
Rock fragments range from 15 to about 35 percent in each horizon. The fragments are mostly sandstone and range from 0.25 inch to about 20 inches in diameter. The A horizon has hue of 10YR or 7.5YR, value of 3 to 5, and chroma of 2 to 4. The Ap horizon has hue of 10YR or 7.5YR, value of 4 to 6 and chroma of 3 to 6 except severely eroded areas also have hue of 5YR and chroma of 8. The E horizon has hue of 10YR or 7.5YR, value of 4 to 6 and chroma of 2 to 4.
