Ap—0 to 18 centimeters (0.0 to 7.1 inches); very dark grayish brown (10YR 3/2), very dark brown (10YR 2/2), moist; silty clay; weak granular structure; hard, firm; 8 percent by volume angular chalk fragments; moderately alkaline, pH 8.2, hellige-truog; abrupt boundary. Lab sample # 40A34660
A11—18 to 38 centimeters (7.1 to 15.0 inches); very dark grayish brown (10YR 3/2), very dark brown (10YR 2/2) and very dark grayish brown (10YR 3/2) crushed, moist; silty clay; moderate and strong fine subangular blocky, and moderate and strong fine granular structure; very hard, very firm; 10 percent by volume angular 2-39-75 millimeter chalk fragments; moderately alkaline, pH 8.2, hellige-truog; clear wavy boundary. Lab sample # 40A34661. Boundary has an amplitude of plus or minus 4" in pit.
