    AP—0 to 18 centimeters (0.0 to 7.1 inches); dark brown (10YR 3/3), grayish brown (10YR 5/2), dry; silty clay loam; fine granular structure; slightly hard, friable, moderately sticky, moderately plastic; 21.0 very fine and fine roots; 21.0 very fine and fine interstitial pores; fragments; extremely acid, pH 4.0, unspecified; gradual smooth boundary. Lab sample # 40A23460
    A12—18 to 36 centimeters (7.1 to 14.2 inches); very dark grayish brown (10YR 3/2), grayish brown (10YR 5/2), dry; silty clay loam; massive parts to fine granular; hard when dry, friable, moderately sticky, moderately plastic; 21.0 very fine and fine roots; 21.0 very fine and fine interstitial and tubular pores; fragments; extremely acid, pH 4.3, unspecified; abrupt wavy boundary. Lab sample # 40A23461
    C1G—36 to 56 centimeters (14.2 to 22.0 inches); strong brown (7.5YR 5/6), light brownish gray (10YR 6/2), dry; silty clay; 3 percent brownish yellow (10YR 6/6) fine distinct and 3 percent strong brown (7.5YR 5/6) fine distinct mottles; weak coarse subangular blocky structure; extremely hard, firm, moderately sticky, moderately plastic; 21.0 very fine and fine roots; 21.0 very fine and fine tubular pores; light gray (2.5Y 7/2), dry, coats in root channels and/or pores; fragments; very strongly acid, pH 4.5, unspecified; gradual smooth boundary. Lab sample # 40A23462
    2C2G—56 to 79 centimeters (22.0 to 31.1 inches); strong brown (7.5YR 5/6) and black (10YR 2/1), gray (5Y 6/1) and dark gray (5Y 4/1), dry; silty clay; 3 percent yellowish red (5YR 5/6) fine prominent mottles; massive parts to very coarse prismatic; extremely hard, firm, moderately sticky, very plastic; 21.0 very fine and fine roots; 3.0 very fine and fine tubular pores; light gray (2.5Y 7/2), dry, coats in root channels and/or pores; fragments; very strongly acid, pH 4.5, unspecified; gradual smooth boundary. Lab sample # 40A23463
    2C3G—79 to 130 centimeters (31.1 to 51.2 inches); strong brown (7.5YR 5/6) and brown (7.5YR 4/4), gray (N 6/0) and dark gray (5Y 4/1), dry; silty clay; 3 percent strong brown (7.5YR 5/6) fine prominent and 3 percent brown (10YR 5/3) fine distinct mottles; weak very coarse prismatic structure; extremely hard, firm, moderately sticky, moderately plastic; 21.0 very fine and fine roots; 21.0 very fine and fine tubular pores; fragments; very strongly acid, pH 4.5, unspecified; gradual smooth boundary. Lab sample # 40A23464. These stains are also affected by organic root remains and sulfur-like residues.
    2C4G—130 to 160 centimeters (51.2 to 63.0 inches); dark gray (5Y 4/1) and gray (N 5/0) and dark greenish gray (5GY 4/1), gray (N 5/0) and black (N 2/0), dry; silty clay; 1 percent yellowish brown (10YR 5/6) fine distinct mottles; massive; extremely hard, firm, moderately sticky, moderately plastic; 3.0 very fine and fine tubular pores; fragments; extremely acid, pH 4.0, unspecified. Lab sample # 40A23465. The dark colors appear to be blotches from carbonized fragments of tules and are accompanied by hydrogen sulfide odor from anaerobic bacteria activity; organic remains replace roots here; reactions range from extremely acid. This horizon is wet and mucky and hard to observe in place.
