    1Ap—0 to 13 centimeters (0.0 to 5.1 inches); dark grayish brown (10YR 4/2) interior clay; moderate fine subangular blocky structure; firm; 5.5 fine roots throughout; fragments; very strongly acid, pH 5.0, hellige-truog; clear wavy boundary. Lab sample # 85P03967; very moist when described;. Clay eontenct exceeds 60% in all horizons.; many fine roots throughout
    1Bw1g—13 to 33 centimeters (5.1 to 13.0 inches); gray (10YR 5/1) interior clay; 30 percent strong brown (7.5YR 5/6) medium prominent mottles; weak coarse subangular blocky structure; very sticky, very plastic; 0.5 very fine roots throughout; fragments; very strongly acid, pH 5.0, hellige-truog; clear wavy boundary. Lab sample # 85P03968; very moist when described;.
