    Ap—0 to 15 centimeters (0.0 to 5.9 inches); very dark gray (10YR 3/1), black (10YR 2/1), moist; silty clay; moderate fine subangular blocky, and moderate fine granular structure; very hard, friable, very sticky, moderately plastic; fragments; moderately alkaline, pH 8.0, hellige-truog. Lab sample # 40A34942
    A12—15 to 36 centimeters (5.9 to 14.2 inches); very dark gray (10YR 3/1), black (10YR 2/1), moist; silty clay; moderate and strong very fine and fine angular blocky, and weak angular blocky structure; extremely hard, very firm, very sticky, moderately plastic; 0.5 fine pores; fragments; moderately alkaline, pH 8.0, hellige-truog. Lab sample # 40A34943
    A13—36 to 61 centimeters (14.2 to 24.0 inches); very dark gray (10YR 3/1), black (10YR 2/1), moist; silty clay; strong very fine and fine angular blocky structure; extremely hard; 3.0 fine pores; pressure faces; fragments; moderately alkaline, pH 8.0, hellige-truog. Lab sample # 40A34944
    A14—61 to 84 centimeters (24.0 to 33.1 inches); very dark gray (10YR 3/1), black (10YR 2/1), moist; silty clay; moderate coarse subangular blocky, and moderate fine angular blocky structure; very firm, very plastic; 1 percent carbonate masses; fragments. Lab sample # 40A34945
