    Ap—0 to 15 centimeters (0.0 to 5.9 inches); dark grayish brown (10YR 4/2), grayish brown (10YR 5/2), dry; Error; weak medium and coarse granular, and platy structure; friable; fragments; moderately acid, pH 5.8; abrupt smooth boundary. Lab sample # OSU0009259. Considerable erosion has probably taken place and part of the BE layer has probably been mixed with the Ap layer.
    BE—15 to 25 centimeters (5.9 to 9.8 inches); brown (10YR 4/3), grayish brown (10YR 5/2), dry; Error; firm; 15 percent faint clay films; 1 percent fine faint grayish brown (10YR 5/2), moist, masses of reduced iron; fragments; moderately acid, pH 5.8; clear wavy boundary. Lab sample # OSU0009260
    B1—25 to 38 centimeters (9.8 to 15.0 inches); dark yellowish brown (10YR 3/4) and gray (10YR 5/1) and dark grayish brown (10YR 4/2) Error; strong medium and coarse subangular blocky, and prismatic structure; firm; clay films; fragments; moderately acid, pH 5.6; abrupt smooth boundary. Lab sample # OSU0009261. Roots are very evident in place. Very compact and dense. A few small shale fragments encountered and horizon appears to increase in density and compactness with depth.
    B2—38 to 48 centimeters (15.0 to 18.9 inches); very dark grayish brown (10YR 3/2) and dark grayish brown (10YR 4/2) and dark yellowish brown (10YR 4/4) Error; strong coarse prismatic, and strong subangular blocky structure; extremely firm; clay films; fragments; moderately acid, pH 5.6; gradual irregular boundary. Lab sample # OSU0009262. Structure very evident in places with good vertical cleavage but not many horizontal fractures. Roots located along fractures. Very compact and dense.
    B3—48 to 61 centimeters (18.9 to 24.0 inches); dark yellowish brown (10YR 4/4) and dark grayish brown (10YR 4/2) and very dark grayish brown (10YR 3/2) Error; strong subangular blocky, and strong coarse prismatic structure; extremely firm; clay films; fragments; moderately acid, pH 6.0; gradual irregular boundary. Lab sample # OSU0009263. Prismatic structure evident in place; very little horizontal cleavage. Roots located along cleavage planes. Very compact and dense.
