    Ap—0 to 18 centimeters (0.0 to 7.1 inches); dark brown (10YR 3/3), brown (10YR 5/3), dry; gravelly loam; weak very fine and fine subangular blocky structure; slightly hard, very friable, slightly sticky, slightly plastic; 3.0 medium roots; 15 percent by volume rounded 2-?-20 millimeter unspecified fragments; noneffervescent; slightly alkaline, pH 7.6, phenol red; abrupt smooth boundary. Lab sample # 69C00612. 15 percent rounded fragments less than 19 mm diameter
    C1—18 to 28 centimeters (7.1 to 11.0 inches); brown (10YR 4/3), pale brown (10YR 6/3), dry; gravelly loam; moderate very fine and fine subangular blocky structure; slightly hard, very friable, slightly sticky, slightly plastic; 3.0 medium and coarse roots; 10 percent by volume 20-?-75 millimeter unspecified fragments and 15 percent by volume rounded 2-?-20 millimeter unspecified fragments; strong effervescence; moderately alkaline, pH 8.0, phenol red; gradual wavy boundary. Lab sample # 69C00613. 15 percent rounded fragments less than 19 mm diameter, 10 percent between 19 mm and 76 mm diameter, some fragments have lime coatings.
    IIC2—28 to 51 centimeters (11.0 to 20.1 inches); brown (10YR 4/3), pale brown (10YR 6/3), dry; very gravelly loam; massive; soft, very friable, slightly sticky, nonplastic; 0.5 fine to coarse roots; 5 percent by volume 75-162-250 millimeter unspecified fragments and 15 percent by volume 20-?-75 millimeter unspecified fragments and 35 percent by volume rounded 2-?-20 millimeter unspecified fragments; strong effervescence; moderately alkaline, pH 8.2, thymol-blue; gradual wavy boundary. Lab sample # 69C00614. 35 percent rounded fragments less than 19 mm diameter, 15 percent between 19 mm and 76 mm diameter, 5 percent larger than 76 mm diameter, most of the fragments are coated with lime.
    IIIC3—51 to 152 centimeters (20.1 to 59.8 inches); dark grayish brown (10YR 4/2) and yellowish brown (10YR 5/4), light brownish gray (10YR 6/2) and light yellowish brown (10YR 6/4), dry; very gravelly sandy loam; single grain; loose, loose, nonsticky, nonplastic; 0.1 roots; carbonate concretions; 10 percent by volume 75-162-250 millimeter unspecified fragments and 25 percent by volume 20-?-75 millimeter unspecified fragments and 50 percent by volume rounded 2-?-20 millimeter limestone-sandstone fragments; strong effervescence; moderately alkaline, pH 8.2, thymol-blue.
