    A—0 to 8 centimeters (0.0 to 3.1 inches); pale brown (10YR 6/3), yellowish brown (10YR 5/4), moist; loam; weak medium platy parts to weak fine subangular blocky structure; slightly hard, friable; 21.0 very fine and fine roots throughout; fragments; violent effervescence, by hcl, 1n; moderately alkaline, pH 8.2, hellige-truog; clear smooth boundary. Lab sample # 98P02451; observed in trench. Many distinct continuous white (10YR 8/1) calcium carbonate coatings on rock fragments; 5 percent subangular limestone fragments 2 to 20 mm in diameter, and 2 percent subangular chert fragments 2 to 20 mm in diameter. The A horizon has hue of 7.5YR or 10YR, value of 6 or 7, and chroma of 2 to 4. Texture is loam or clay loam with a clay content of 18 to 30 percent. Limestone and chert fragments range from 0 to 15 percent. (2 to 10 inches thick)
    Bk1—8 to 41 centimeters (3.1 to 16.1 inches); pale brown (10YR 6/3), yellowish brown (10YR 5/4), moist; gravelly clay loam; weak fine and medium subangular blocky structure; hard when dry, firm; 21.0 very fine roots and fine and medium roots throughout; fragments; violent effervescence, by hcl, 1n; moderately alkaline, pH 8.2, hellige-truog; clear wavy boundary. Lab sample # 98P02452; observed in trench. Many distinct continuous white (10YR 8/1) calcium carbonate coatings on rock fragments; 15 percent subangular limestone fragments 2 to 20 mm in diameter, 5 percent subangular limestone fragments 20 to 75 mm in diameter, 2 percent subrounded chert fragments 2 to 20 mm in diameter, and 3 percent angular limestone channers. The Bk horizon has hue of 7.5YR or 10YR, value of 6 or 7, and chroma of 3 or 4. Texture of the fine earth fraction is loam or clay loam with a total clay content of 25 to 40 percent. Limestone and shale pebbles range from 0 to 25 percent.
    Bk2—41 to 61 centimeters (16.1 to 24.0 inches); very pale brown (10YR 7/3), brownish yellow (10YR 6/6), moist; gravelly loam; weak fine and medium subangular blocky structure; slightly hard, friable; 3.0 fine and medium roots throughout; fragments; violent effervescence, by hcl, 1n; moderately alkaline, pH 8.2, hellige-truog; abrupt smooth boundary. Lab sample # 98P02453; observed in trench. Common coarse and very coarse irregular very pale brown (10YR 8/3) slightly hard masses of calcium carbonate and common very coarse and extremely coarse plate-like pale yellow (25YR 8/3) slightly hard calcium carbonate nodules throughout, calcium carbonate nodules are weathered, soft limestone fragments that would slake in water; many distinct continuous white (10YR 8/1) calcium carbonate coatings on rock fragments; 15 percent subangular limestone fragments 2-20 mm in diameter. The Bk horizon has hue of 7.5YR or 10YR, value of 6 or 7, and chroma of 3 or 4. Texture of the fine earth fraction is loam or clay loam with a total content of 25-40%. (Combined thickness of Bk horizons is 18 to 30 inches)

Lab sample # 98P02454; observed in trench. Weathered marly limestone bedrock; many distinct continuous white (10YR 8/1) calcium carbonate coatings in fractures. The Cr layer has hue of 10YR or 2.5Y, value of 7 or 8, and chroma of 1 to 3. It is weakly to moderately cemented weathered limestone or shale bedrock.
