Solum thickness ranges from 40 to 60 inches. Depth to the base of the argillic horizon ranges from 30 to 40 inches. Depth to bedrock ranges from 40 to 72 inches. Shale is the dominant rock fragment but thin flat siltstone or sandstone channers are in many pedons. Bt horizons and 15 to 90 percent in the BC and C horizons.
Reaction is strongly or very strongly acid throughout unless the soil has been limed.
The Ap horizon has hue of 10YR, value of 3 through 5, and chroma of 2 through 4. Dry value is 6 or more. Texture of the fine-earth fraction is silt loam or loam. The B horizon has hue of 7.5YR or 10YR, value of 4 through 6, and chroma of 4 through 8. Texture of the fine-earth fraction is loam, silt loam, clay loam or silty clay loam with more than 40 percent silt.
