Rock fragments consist of dark phyllite, slate, and schist. Rock fragments, by volume, larger than 10 inches range from 0 to 20 percent in the surface and 0 to 5 percent in the subsoil and substratum. The soil, below the A or Ap horizon and above a depth of 30 inches, is very strongly acid to moderately acid where not limed, and ranges from very strongly acid to slightly acid below a depth of 30 inches. Unplowed areas have 0 horizons l to 4 inches thick underlain by a thin A horizon with hue of 10YR, value of 2 to 3 and chroma of l to 3. The Ap horizon has hue of 10YR, value of 2 to 4, and chroma of 2 or 3.
Structure is weak or moderate fine or medium granular.
Consistence is friable or very friable. Some pedons have a thin E horizon. The upper part of the Bw horizon has hue of 7.5YR to 2.5Y, value of 4 or 5, and chroma of 3 to 6. The lower part of the Bw horizon has hue of 2.5Y or 5Y, value of 4 or 5, and chroma of 3 to 6. Redoximorphic depletions and concentrations are few or common in the upper part of the Bw and from few to many in the lower part.
