    A11—0 to 10 centimeters (0.0 to 3.9 inches); very dark brown (10YR 2/2) and very dark grayish brown (10YR 3/2) crushed silt loam; moderate fine granular structure; friable; 21.0 fine roots; 21 percent fine worm casts; fragments; gradual boundary. Lab sample # 40A11085. Worm casts mainly as individual pellets; post-Farmdale loess.
    B1—10 to 20 centimeters (3.9 to 7.9 inches); very dark grayish brown (10YR 3/2) and dark brown (10YR 3/3) and dark brown (10YR 3/3) crushed silt loam; weak and moderate fine subangular blocky structure; friable; 21.0 roots; 21 percent spherical worm casts and 21 percent threadlike worm casts; fragments; gradual boundary. Lab sample # 40A11086
    B2—20 to 33 centimeters (7.9 to 13.0 inches); dark brown (10YR 3/3) and very dark grayish brown (10YR 3/2) silt loam; weak fine subangular blocky structure; friable; 3.0 roots; 21 percent worm casts; fragments; gradual boundary. Lab sample # 40A11087
    B3—33 to 48 centimeters (13.0 to 18.9 inches); dark yellowish brown (10YR 3/4) and brown (10YR 4/3) crushed silt loam; weak medium subangular blocky parts to very fine granular structure; friable; 3.0 roots; 1 percent dark brown (10YR 3/3) worm casts and 1 percent very dark grayish brown (10YR 3/2) worm casts and 3 percent spherical worm casts; fragments; clear boundary. Lab sample # 40A11088. Granular structure appears to be mainly worm cast pellets.
    C1—48 to 64 centimeters (18.9 to 25.2 inches); brown (10YR 4/3) and brown (10YR 5/3) crushed silt loam; massive; very friable; 21 percent worm casts; fragments; abrupt boundary. Lab sample # 40A11089. Structure breaks into very fine individual worm cast pellets.
    C2—64 to 122 centimeters (25.2 to 48.0 inches); brown (10YR 5/3) and brown (10YR 5/3) crushed silt loam; massive; friable; 3 percent worm casts and fine carbonate concretions; fragments; slight effervescence. Lab sample # 40A11090. Sampled 36 to 48 inches; post-Farmdale loess.
