    A1p—0 to 18 centimeters (0.0 to 7.1 inches); black (10YR 2/1) and very dark brown (10YR 2/2) rubbed, very dark gray (10YR 3/1), dry; silty clay loam; 30 percent clay; moderate fine granular structure; friable; fragments; clear boundary. Lab sample # 40A11185. Numerous clear (uncoated) coarse silt and some fine sand grains.
    A12—18 to 28 centimeters (7.1 to 11.0 inches); black (10YR 2/1) and very dark brown (10YR 2/2) rubbed, very dark gray (10YR 3/1), dry; silty clay loam; 32 percent clay; weak and moderate fine granular structure; friable; fragments; gradual boundary. Lab sample # 40A11186. Numerous clear (uncoated) coarse silt and some fine sand grains.
    A3—28 to 41 centimeters (11.0 to 16.1 inches); black (10YR 2/1) and very dark brown (10YR 2/2) rubbed, very dark gray (10YR 3/1), dry; silty clay loam; moderate fine granular, and fine subangular blocky structure; friable; 3.0 fine tubular pores; fragments; gradual boundary. Lab sample # 40A11187. 2 to 3-mm. spots of yellowish brown; the horizon contains several nearly horizontal krotovinas about 1 inch in diameter filled with yellowish brown silty clay loam.
    B21—41 to 53 centimeters (16.1 to 20.9 inches); 50 percent dark grayish brown (10YR 4/2) and 50 percent very dark gray (10YR 3/1) and very dark gray (10YR 3/1) exterior and dark grayish brown (10YR 4/2) interior silty clay loam; moderate very fine and fine subangular blocky structure; friable; 3.0 fine tubular pores; fragments; clear wavy boundary. Lab sample # 40A11188. Few fine spherical dark oxide concretions; mottling appears due to physical mixing of materials for the most part; patches of smooth shiny surfaces on peds and in pores.
    B22—53 to 76 centimeters (20.9 to 29.9 inches); brown (10YR 4/3) silty clay loam; weak fine subangular blocky structure; friable; 21.0 fine tubular pores; 1 percent fine and medium white (10YR 8/1) carbonate concretions; fragments; noneffervescent; clear boundary. Lab sample # 40A11189. Patches of smooth shiny surfaces on most peds; common dark spherical oxide concretions; carbonate concretions in lower 1 to 2 inches; fingers of dark gray (10YR 3.5/1) 2 to 4 mm. across extend into the upper part of this horizon from the horizon above (have the appearance of old root channels or worm burrows).
    B3—76 to 89 centimeters (29.9 to 35.0 inches); light olive brown (2.5Y 5/3) silty clay loam; 1 percent light olive brown (2.5Y 5/4) fine faint and 1 percent light olive brown (2.5Y 5/6) fine faint mottles; weak fine subangular blocky, and weak prismatic structure; friable; 21.0 very fine and fine tubular pores; 1 percent fine noncoherent cemented carbonate concretions; fragments; slight effervescence; clear boundary. Lab sample # 40A11190. Few thin vertical streaks of dark gray appear to be old root channels, wormholes, or cracks.
    C1—89 to 107 centimeters (35.0 to 42.1 inches); 50 percent grayish brown (2.5Y 5/2) and 50 percent light olive brown (2.5Y 5/4) silt loam; weak medium and coarse prismatic parts to medium subangular blocky structure; hard, friable; 21.0 very fine and fine tubular pores; 3 percent coarse and very coarse irregular noncoherent cemented white (10YR 8/1) carbonate concretions; fragments; slight effervescence; clear boundary. Lab sample # 40A11191. Few fine dark oxide concretions; concretions are soft on the outside and hard inside.
    C2—107 to 119 centimeters (42.1 to 46.9 inches); 50 percent grayish brown (2.5Y 5/2) and 50 percent light olive brown (2.5Y 5/4) silt loam; weak medium and coarse prismatic parts to medium subangular blocky structure; hard, friable; 21.0 very fine and fine tubular pores; 30 percent carbonate coats on lower surfaces of peds or rocks; 3 percent coarse and very coarse irregular noncoherent cemented white (10YR 8/1) carbonate concretions; fragments; slight effervescence; clear boundary. Lab sample # 40A11192. Contains a number of pebbles 1/2 to 2 inches in diameter and enough sand to be noticeable. The pebbles occur mostly in the upper part of the horizon and probably represent a stone line, though not a distinct or continuous one. The matrix material has the feel and consistence of the loess in the overlying horizon.
    IIC3—119 to 152 centimeters (46.9 to 59.8 inches); yellowish brown (10YR 5/4) and grayish brown (10YR 5/2) exterior clay loam; 32 percent clay; weak coarse prismatic structure; very hard, firm; 3.0 fine tubular pores; 30 percent grayish brown (10YR 5/2), moist, clay films in root channels and/or pores and 30 percent brown (10YR 5/3), moist, clay films in root channels and/or pores; 3 percent white (10YR 8/1) carbonate concretions; fragments; slight effervescence. Lab sample # 40A11193. Few smooth shiny patches suggestive of clay films; prism faces extend across boundary between horizons C2 and IIC3.; continuous - phpvsfiid 186278; continuous - phpvsfiid 186279; continuous - phpvsfiid 186278; continuous - phpvsfiid 186279
    IIC4—152 to 213 centimeters (59.8 to 83.9 inches); yellowish brown (10YR 5/6) clay loam; 31 percent clay; 3 percent strong brown (7.5YR 5/8) fine distinct and 3 percent grayish brown (10YR 5/2) fine distinct mottles; 3 percent coarse and very coarse white (10YR 8/1) carbonate concretions; fragments. Lab sample # 40A11194. Sampled with bucket auger. There is a visible decrease in abundance of carbonate concretions at about 60 inches.
