    A—0 to 14 centimeters (0.0 to 5.5 inches); very dark grayish brown (10YR 3/2), very dark brown (10YR 2/2), moist; silt loam; moderate fine subangular blocky parts to moderate medium granular structure; slightly hard, friable, slightly sticky, slightly plastic; many (8.0) very fine roots throughout; 3 percent by volume nonflat subangular indurated 2-10-20 millimeter sandstone, unspecified fragments observed by visual inspection method; clear smooth boundary.
    BA—14 to 25 centimeters (5.5 to 9.8 inches); dark grayish brown (10YR 4/2), very dark grayish brown (10YR 3/2), moist; silty clay loam; moderate fine subangular blocky structure; hard, firm, moderately sticky, moderately plastic; many (7.0) very fine roots throughout; 3 percent by volume nonflat subangular indurated 20-40-76 millimeter sandstone, unspecified fragments observed by visual inspection method and 4 percent by volume nonflat subangular indurated 2-10-20 millimeter sandstone, unspecified fragments observed by visual inspection method; clear smooth boundary.
    Bt—25 to 43 centimeters (9.8 to 16.9 inches); brown (10YR 5/3), brown (10YR 4/3), moist; clay; moderate medium subangular blocky structure; very hard, very firm, very sticky, very plastic; common (4.0) very fine roots throughout; 40 percent distinct clay films on all faces of peds; 1 percent fine very weakly coherent cemented iron-manganese concretions and 2 percent fine faint brown (7.5YR 4/4), moist, masses of oxidized iron; 2 percent by volume nonflat subangular indurated 5-10-20 millimeter sandstone, unspecified fragments observed by visual inspection method; gradual smooth boundary.
    Btss—43 to 69 centimeters (16.9 to 27.2 inches); grayish brown (2.5Y 5/2), dark grayish brown (2.5Y 4/2), moist; clay; moderate medium subangular blocky structure; very hard, very firm, very sticky, very plastic; common (2.0) very fine roots throughout; 10 percent distinct slickensides (pedogenic) and 30 percent distinct clay films on all faces of peds; 1 percent fine very weakly coherent cemented iron-manganese concretions and 5 percent fine distinct strong brown (7.5YR 4/6), moist, masses of oxidized iron; 1 percent fine gypsum crystals, unspecified; 1 percent by volume nonflat subangular indurated 20-50-76 millimeter sandstone, unspecified fragments observed by visual inspection method and 2 percent by volume nonflat subangular indurated 5-10-20 millimeter sandstone, unspecified fragments observed by visual inspection method; clear wavy boundary.
    2C—69 to 99 centimeters (27.2 to 39.0 inches); light gray (2.5Y 7/1), gray (2.5Y 5/1), moist; silty clay; structureless massive; very hard, very firm, very sticky, very plastic; few (0.5) very fine roots throughout; 10 percent distinct slickensides (pedogenic); 10 percent coarse prominent olive yellow (2.5Y 6/8), moist, masses of oxidized iron and 20 percent coarse prominent strong brown (7.5YR 5/6), moist, masses of oxidized iron; 2 percent fine gypsum crystals, unspecified; fragments; clear wavy boundary. This horizon was called a 2C. It has massive structure and looks like like soft bedrock. However there are slickensides present. The parent material is clayey shale and the shrinking/swelling over time has formed slickensides. Horizonation may need to be looked at (possibly call it a Bss horizon).
    2Cd—99 to 140 centimeters (39.0 to 55.1 inches); light gray (2.5Y 7/1), gray (2.5Y 5/1), moist; silty clay; structureless massive; 15 percent coarse prominent strong brown (7.5YR 5/8), moist, masses of oxidized iron and 25 percent coarse prominent yellow (2.5Y 7/6), moist, masses of oxidized iron; 5 percent fine gypsum crystals, unspecified; fragments. Clayey shale with the characteristic platy geologic structure. It has bedding planes that are 1 cm or less thick. Historically was called a Cr horizon. Samples were tested and it slaked, so it was called a 2Cd horizon.
