Thickness of the solum ranges from 40 to 80 inches. Depth to the base of the argillic horizon is 35 to 54 inches. Rock fragment lithology is mainly sandstone and shale, with a large amount of quartz gravel. The particle size control section averages 18 to 27 percent clay. It is loam, silt loam, gravelly loam, and sandy loam or gravelly sandy loam.
Reaction is very strongly acid to slightly acid, but limed areas range to neutral.
Rock fragment content ranges from 0 to 30 percent. Where present, the BE, BA, or E horizon has hue of 10YR, value of 4 to 6,and chroma of 3 or 4. They have textures and reaction similar to the Ap horizon. Rock fragment content ranges from 15 to 60 percent in individual horizons. Reaction is very strongly acid to slightly acid.
