    A11—0 to 23 centimeters (0.0 to 9.1 inches); very dark grayish brown (10YR 3/2), very dark brown (10YR 2/2), moist; cobbly silty clay; strong very fine subangular blocky, and strong medium granular structure; firm, moderately sticky, moderately plastic; 21.0 roots; 40 percent by volume limestone, unspecified fragments; gradual boundary. Lab sample # 40A34576. Limestone fragments are dominantly about 3-6"""" across their long axis; about 20-30% of the coarse fragments are smaller than 3"""" across, mostly angular and some fine gravel size; some of the larger fragments appear to be etched.
    A12—23 to 41 centimeters (9.1 to 16.1 inches); brown (10YR 4/3), dark brown (10YR 3/3) crushed, moist; silty clay; strong very fine subangular blocky, and strong medium granular structure; firm, moderately sticky, moderately plastic; 0.5 fine roots; 75-162-250 millimeter limestone, unspecified fragments and 250-425-600 millimeter limestone, unspecified fragments; abrupt wavy boundary. Lab sample # 40A34577. The limestone fragments dominantly are about 3-5"""" thick vertically and are about 4-10"""" across the horizontally lying long axis; vertical cracks between the fractured limestones are mostly less than about 1"""" wide; the soil is concentrated mostly in horizontal bands between apparent layers of the limestone; the tops of the limestone fragments are etched and the outsides are colored with brownish organic and soil stains.
    R—41 to 79 centimeters (16.1 to 31.1 inches); 2 percent clay; 3.0 fine roots; fragments. Lab sample # 40A34578. Indurated crystalline fractured limestone layer to a depth of 25"""" in which the fractures are not wide enough to see and can be distinguished only after the limestone is broken out with a heavy bar and the brownish stains can be seen in the fine fracture planes; at depths between 25-31"""" laminated or very thin bedded, alternating soft limestone that can be broken in the hand, and indurated limestone that is 1 or 2"""" thick and has occasional fractures that are almost indistinguishable prior to breaking with a bar occur; also has thin layers of marl or clay; upper surfaces of the hard limestone are etched and lower surfaces appear to have secondary coatings of indurated CaCO3.
