    Ap—0 to 18 centimeters (0.0 to 7.1 inches); black (10YR 2/1) silt loam; moderate fine granular structure; friable; fragments; clear boundary. Lab sample # 40A11255
    A21—18 to 29 centimeters (7.1 to 11.4 inches); dark grayish brown (10YR 4/2) and very dark gray (10YR 3/1) and yellowish brown (10YR 5/4) and dark grayish brown (10YR 4/2) rubbed silt loam; weak very fine platy, and weak very fine subangular blocky structure; friable; fragments; gradual boundary. Lab sample # 40A11256
    A22—29 to 39 centimeters (11.4 to 15.4 inches); dark grayish brown (10YR 4/2) exterior and dark grayish brown (10YR 4/2) interior and strong brown (7.5YR 5/6) interior and yellowish brown (10YR 5/4) rubbed clay loam; 21 percent yellowish brown (10YR 5/6) fine distinct mottles; moderate and strong very fine and fine subangular blocky structure; firm; fragments; gradual boundary. Lab sample # 40A11257. Very little mixing as evidence by worm casts; pebble band present.
    IIB21—39 to 51 centimeters (15.4 to 20.1 inches); gray (2.5Y 5/1) exterior and gray (2.5Y 5/1) interior and strong brown (7.5YR 5/6) interior and yellowish brown (10YR 5/6) rubbed clay loam; 3 percent yellowish brown (10YR 5/6) fine and medium distinct mottles; moderate and strong very fine and fine subangular blocky structure; firm; fragments; gradual boundary. Lab sample # 40A11258
    IIB22—51 to 66 centimeters (20.1 to 26.0 inches); gray (2.5Y 5/1) and dark yellowish brown (10YR 4/6) rubbed clay loam; 1 percent yellowish brown (10YR 5/6) medium distinct and 3 percent brown (7.5YR 4/4) fine distinct mottles; moderate medium prismatic parts to moderate and strong medium subangular blocky structure; firm; fragments; gradual boundary. Lab sample # 40A11259. If any very dark gray (N 3/0 moist) transported clay is smeared on ped surfaces, it is masked by gray sand coatings.
    IIB23—66 to 86 centimeters (26.0 to 33.9 inches); gray (2.5Y 5/1) and gray (2.5Y 5/1) interior and yellowish brown (10YR 5/6) interior and yellowish brown (10YR 5/4) rubbed clay loam; 3 percent yellowish brown (10YR 5/6) medium distinct mottles; moderate coarse prismatic parts to moderate coarse angular blocky structure; very firm; fragments; diffuse boundary. Lab sample # 40A11260. Very dark gray (N 3/0 moist) transported clay in small root channels and as streaks on ped surfaces; the sand coating on prism faces in above horizons is absent in this horizon.
    IIB24—86 to 104 centimeters (33.9 to 40.9 inches); gray (5Y 5/1) exterior and 75 percent yellowish brown (10YR 5/4) interior and 25 percent gray (5Y 5/1) interior and yellowish brown (10YR 5/4) rubbed and yellowish brown (10YR 5/6) rubbed clay loam; 21 percent yellowish brown (10YR 5/4) medium distinct and 21 percent yellowish brown (10YR 5/6) medium distinct mottles; weak coarse prismatic structure; firm; fragments; gradual boundary. Lab sample # 40A11261. Transported clay is of a lesser extent in this horizon. Mottles occur only on horizontal faces.
    IIB3—104 to 122 centimeters (40.9 to 48.0 inches); gray (5Y 5/1) and yellowish brown (10YR 5/4) and gray (5Y 6/1) and yellowish brown (10YR 5/4) rubbed clay loam; massive; firm; fragments; gradual boundary. Lab sample # 40A11262. Some large vertical faces present. This horizon is transitional to carbonates; the carbonate line being wavy. All horizons above are leached and all below are unleached; fewer small root channels but some larger ones filled with transported clay.
    IIC1—122 to 142 centimeters (48.0 to 55.9 inches); 50 percent dark yellowish brown (10YR 4/4) and 50 percent gray (5Y 6/1) and yellowish brown (10YR 5/4) rubbed and light olive brown (2.5Y 5/4) rubbed clay loam; massive; firm; fragments; diffuse boundary. Lab sample # 40A11263. Some vertical faces.
    IIC2—142 to 160 centimeters (55.9 to 63.0 inches); 50 percent dark yellowish brown (10YR 4/4) and 50 percent gray (5Y 6/1) and light olive brown (2.5Y 5/4) rubbed and yellowish brown (10YR 5/4) rubbed clay loam; massive; firm; fragments. Lab sample # 40A11264
