    A1p—0 to 15 centimeters (0.0 to 5.9 inches); black (10YR 2/1) and black (10YR 2/1) rubbed silty clay loam; 30 percent clay; massive parts to weak fine granular, and subangular blocky; friable; fragments; clear boundary. Lab sample # 40A11195
    A12—15 to 28 centimeters (5.9 to 11.0 inches); black (10YR 2/1) and black (10YR 2/1) rubbed silty clay loam; moderate fine granular structure; friable; fragments; gradual boundary. Lab sample # 40A11196
    A3—28 to 43 centimeters (11.0 to 16.9 inches); very dark brown (10YR 2/2) and very dark grayish brown (10YR 3/2) rubbed silty clay loam; 33 percent clay; 20 percent very dark grayish brown (10YR 3/2) mottles; moderate fine subangular blocky, and medium granular structure; friable; fragments; gradual wavy boundary. Lab sample # 40A11197. Few fine hard oxide concretions; mottles in lower part of horizon only.
