    AP—0 to 20 centimeters (0.0 to 7.9 inches); dark grayish brown (10YR 4/2), very dark gray (10YR 3/1) and very dark brown (10YR 2/2), moist; silt loam; moderate very fine and fine granular structure; slightly hard, moderately sticky, slightly plastic; 21.0 fine pores; fragments; 5.9000001 Chlorophenol re; moderately acid, pH 6.0, bromthymol blue. Lab sample # 40A07156. this layer is underlain abruptly by a plowsole 5 mm thick that is similar in color but hard and more compact-slightly to moderately dense but moderate number of fine channels
    A31—20 to 30 centimeters (7.9 to 11.8 inches); dark grayish brown (10YR 4/2), very dark brown (10YR 2/2), moist; silt loam; weak coarse angular blocky, and moderate fine granular structure; hard when dry, moderately sticky, slightly plastic; 21.0 very fine and fine roots; fragments; 6.19999981 Chlorophenol re; slightly acid, pH 6.2, bromthymol blue. Lab sample # 40A07157. vertical faces of prisms faintly or very weakly coated with light-gray or light brownish gray very fine siliceous coating that increases somewhat with depth; the color of the upper part is very slightly darker and browner than the top horizon, and it is very gradually lighter and browner with depth
    A32—30 to 38 centimeters (11.8 to 15.0 inches); dark grayish brown (10YR 4/2), very dark brown (10YR 2/2), moist; silt loam; weak coarse angular blocky, and moderate fine granular structure; hard when dry, moderately sticky, slightly plastic; 21.0 very fine and fine roots; fragments; 6.4000001 Chlorophenol re; slightly acid, pH 6.3, bromthymol blue. Lab sample # 40A07158. faintly more grayish coating on vertical cracks
    B21—38 to 61 centimeters (15.0 to 24.0 inches); dark grayish brown (10YR 4/2), very dark grayish brown (10YR 3/2), moist; silt loam; weak prismatic structure; very hard, moderately sticky, slightly plastic; 21.0 very fine roots; fragments; neutral, pH 6.6, bromthymol blue. Lab sample # 40A07159. aggregates, especially on vertical cracks, are slightly but distinctly coated with light-gray or light brownish gray very fine siliceous coating as in above layer
    B22—61 to 76 centimeters (24.0 to 29.9 inches); brown (10YR 5/3), very dark grayish brown (10YR 3/2), moist; silt loam; weak prismatic structure; very hard, moderately sticky, slightly plastic; 21.0 very fine and fine roots; fragments; 6.80000019 Chlorophenol re; neutral, pH 6.8, bromthymol blue. Lab sample # 40A07160. aggregates smaller, browner, and less grayish coating than above; some root channels filled with darker material; very slight grayish coating on main vertical cracks but practically none on the other cracks
    B23—76 to 94 centimeters (29.9 to 37.0 inches); brown (10YR 5/3), dark grayish brown (10YR 4/2), moist; silt loam; medium and coarse subangular blocky structure; hard when dry; 21.0 very fine and fine roots; fragments; 6.80000019 Chlorophenol re; neutral, pH 7.0, bromthymol blue. Lab sample # 40A07161. structure is slightly less harsh than above layer but distinctly lighter brown; very faint or no grayish coating
    B3—94 to 119 centimeters (37.0 to 46.9 inches); brown (10YR 5/3), brown (10YR 4/3), moist; silt loam; weak medium and coarse angular blocky structure; hard when dry, friable, moderately sticky, slightly plastic; 21.0 very fine roots; fragments; 7.4000001 Chlorophenol re; noneffervescent, by hcl, unspecified; neutral, pH 7.2, bromthymol blue. Lab sample # 40A07162. aggregates not appreciably coated; somewhat massive; scattered very hard rounded nodules of soil material that are dense inside
    C1—119 to 147 centimeters (46.9 to 57.9 inches); pale brown (10YR 6/3), brown (10YR 4/3), moist; silt loam; weak medium angular blocky structure; slightly hard, slightly sticky, slightly plastic; 21.0 very fine roots; fragments; 7.5999999 Chlorophenol re; noneffervescent, by hcl, unspecified; slightly alkaline, pH 7.4, bromthymol blue. Lab sample # 40A07163. nearly massive
    C2—147 to 183 centimeters (57.9 to 72.0 inches); brown (10YR 5/3) and light yellowish brown (10YR 6/4), brown (10YR 4/3), moist; silty clay loam; weak fine and medium angular blocky structure; very hard, slightly sticky, slightly plastic; 1.0 roots; fragments; 8 Chlorophenol re; noneffervescent, by hcl, unspecified; slightly alkaline, pH 7.8, bromthymol blue. Lab sample # 40A07164. this material although likely mostly from loess, is influenced by basaltic sand and probably is an old buried soil horizon; somewhat massive; very few lime veins in lower part
