The Ap or A horizon has hue of 2.5YR to 10YR, value of 3 to 5, and chroma of 1 to 3. Some pedons are overwashed with fine sandy loam or textures similar to the A horizon, but have hue of 2.5YR to 7.5YR, value of 4 or 5, and chroma of 4. The overwash material is less than 20 inches thick. Reaction of the Ap or A horizon ranges from moderately acid to slightly alkaline. The Bk or Bw horizon has hue of 2.5YR to 10YR, value of 3 to 6, and chroma of 1 to 6.
Reaction ranges from slightly acid to moderately alkaline.
Visible calcium carbonate in the form of masses and films ranges from 0 to 5 percent by volume. The C horizon has hue of 2.5YR to 7.5YR, value of 3 to 6, and chroma of 1 to 6. Thin strata of coarser or fine textures occur in this horizon. Reaction is moderately alkaline and calcareous. Visible calcium carbonate in the form of masses and films ranges from 0 to 5 percent by volume.
