    Oi—0 to 3 centimeters (0.0 to 1.2 inches); slightly decomposed plant material; fragments.
    A1—3 to 18 centimeters (1.2 to 7.1 inches); very dark brown (10YR 2/2), brown (10YR 4/3), dry; loam; moderate fine granular structure; very friable; 10.0 fine to coarse roots; 3 percent by volume 2-39-75 millimeter unspecified fragments; strongly acid, pH 5.4, hellige-truog; clear wavy boundary. Lab sample # MU042017. Rubbed colors were the same as unrubbed.
    A2—18 to 46 centimeters (7.1 to 18.1 inches); dark brown (7.5YR 3/4), light brown (7.5YR 6/4), dry; stony loam; moderate very fine and fine subangular blocky structure; friable; 3.0 fine and medium roots; 35 percent faint dark brown (10YR 3/3) organic stains; 1 percent by volume 75-162-250 millimeter unspecified fragments and 8 percent by volume 250-425-600 millimeter unspecified fragments and 11 percent by volume 2-39-75 millimeter unspecified fragments; moderately acid, pH 5.6, hellige-truog; abrupt wavy boundary.
