Thickness of the solum ranges from 30 to 50 inches. Depth to bedrock is more than 40 inches. Rock fragments, mainly gravel, channers, and flagstones range from 5 to 35 percent by volume, in the upper part of the solum, from 15 to 50 percent in the lower part of the solum and from 20 to 65 percent in the substratum. Weighted average for rock fragment volume is less than 35 percent in the particle-size control section. The Ap or A horizon has hue of 10YR or 2.5Y, value of 3 or 4, and chroma of 2 through 4.
Texture is silt loam or loam in the fine earth fraction.
Reaction ranges from extremely acid to moderately acid. The B horizon has hue of 7.5YR through 2.5Y, value of 4 through 6, and chroma of 3 through 6. In some pedons there are redoximorphic features in the lower part of the B horizon. Texture is silt loam, loam or fine sandy loam in the fine-earth fraction. Structure is subangular blocky, prismatic or granular.
