    A—0 to 8 centimeters (0.0 to 3.1 inches); light olive brown (2.5Y 5/3) loam; weak and moderate very fine subangular blocky structure; firm; 6.0 very fine and fine roots and 0.1 medium roots; fragments; slightly alkaline, pH 7.6, hellige-truog; clear smooth boundary. Lab sample # MU014113
    C1—8 to 25 centimeters (3.1 to 9.8 inches); strong brown (7.5YR 5/6) and gray (2.5Y 5/1) and grayish brown (2.5Y 5/2) and light olive brown (2.5Y 5/4) gravelly silty clay loam; weak fine subangular blocky structure; firm; 3.0 very fine to medium roots; 20 percent by volume 2-39-75 millimeter unspecified fragments; slightly alkaline, pH 7.5, hellige-truog; clear wavy boundary. Lab sample # MU014114. (Note: The 2.5Y colors are a lithochromic mixture. The gravel is soft to hard with a few bits of coal. There are pockets of dark brown (10YR 3/3) A horizon material along fractures and channels.)
    C2—25 to 51 centimeters (9.8 to 20.1 inches); very dark grayish brown (10YR 3/2) and strong brown (7.5YR 5/8) and gray (5Y 5/1) and gray (5Y 6/1) silty clay loam; weak fine subangular blocky structure; firm; 0.1 very fine roots and 0.1 medium roots and 3.0 fine roots; fragments; moderately acid, pH 6.0, hellige-truog; clear wavy boundary. Lab sample # MU014115. (Note: This is decomposing shale which crushes to SICL. The structure includes mixed rock structure.)
    C3—51 to 94 centimeters (20.1 to 37.0 inches); gray (5Y 6/1) and very dark grayish brown (10YR 3/2) and brownish yellow (10YR 6/8) silt loam; firm; 3.0 very fine and fine roots and 0.1 medium roots; coarse interstitial pores; fragments; neutral, pH 7.3, hellige-truog; diffuse boundary. Lab sample # MU014116. (Note: Fractured saprolitic shale with intermittent pockets of 10YR material, which is located along fractures and interstices. The pores are common.)
    C4—94 to 122 centimeters (37.0 to 48.0 inches); dark brown (10YR 3/3) and dark yellowish brown (10YR 4/6) and yellowish brown (10YR 5/6) silt loam; weak fine subangular blocky structure; firm; 0.1 very fine to medium roots; fragments; moderately acid, pH 6.0, hellige-truog; clear wavy boundary. Lab sample # MU014117. (Note: 75 percent soft to hard saprolitic shale and 25 percent original soil. Structure is mixed rock structure and soil structure.)
    C5—122 to 152 centimeters (48.0 to 59.8 inches); dark brown (10YR 3/3) gravelly clay loam; 1 percent gray (5Y 6/1) and 10 percent gray (2.5Y 6/1) mottles; massive; firm; 0.1 very fine and fine roots; 1 percent brownish yellow (10YR 6/8) masses of oxidized iron; 1 percent light yellowish brown (2.5Y 6/3); fragments; neutral, pH 7.1, hellige-truog. Lab sample # MU014118. Note: There are many soft to hard black coal sand grains.
