Rock fragments range from 0 to 5 percent in the solum, with gravelly subhorizons in some pedons, and from 0 to 70 percent in the 2C horizon. Rock fragments are dominated by sedimentary source material with some erratics of igneous or metamorphic origin. The Ap on a horizon has hue of 7.5YR through 2.5Y, value of 3 through 5, and chroma of 2 through 4. It is silt loam, loam, very fine sandy loam, or fine sandy loam. The Ap horizon has granular or subangular blocky structure and very friable or friable consistence.
Reaction ranges from very strongly acid to moderately acid, unless limed.
The Bw horizon has hue of 7.5YR through 5Y, value of 4 through 6, and chroma of 3 through 8. It is silt loam or very fine sandy loam. Bw horizons have weak or moderate, granular or subangular blocky structure except some subhorizons can be massive. Consistence is very friable to firm, some pedons may have a BC horizon. Reaction ranges from very strongly acid to moderately acid.
