    A—0 to 10 centimeters (0.0 to 3.9 inches); very dark brown (10YR 2/2) highly organic very stony fine sandy loam; weak fine granular structure; very friable; fragments. Lab sample # 40A03347. There is no coarse skeleton except for the 1-3 inch in diameter granite and schist boulders on and in the horizon. These stones average 2 to 3 feet apart on the surface. Surface has a 1-1 1/2 foot microrelief principally related to the stones rather than to previous wind throw by trees.
    Bw1—10 to 23 centimeters (3.9 to 9.1 inches); dark yellowish brown (10YR 4/4) and yellowish brown (10YR 5/6) and yellowish brown (10YR 5/8) fine sandy loam; weak fine granular parts to subangular blocky structure; very friable, nonsticky, nonplastic; 12 percent by volume 20-48-75 millimeter metamorphic, unspecified fragments. Lab sample # 40A03348. Skeleton occurs mostly in the 1/4-2 inch diameter range. Large stones occur at distances of about 6 feet. This horizon has distinctly stronger chroma than the horizon below.
    Bw2—23 to 41 centimeters (9.1 to 16.1 inches); dark yellowish brown (10YR 4/4) fine sandy loam; weak very fine granular structure; very friable, nonsticky, nonplastic; 12 percent by volume 20-48-75 millimeter metamorphic, unspecified fragments. Lab sample # 40A03349. When removed, the soil mass consists of about 20-30 percent one inch subangular blocky peds.
    Bw3—41 to 66 centimeters (16.1 to 26.0 inches); olive brown (2.5Y 4/4) gravelly fine sandy loam; weak subangular blocky parts to weak fine granular structure; friable, nonsticky, nonplastic; 25 percent by volume 20-48-75 millimeter metamorphic, unspecified fragments. Lab sample # 40A03350
    Bw4—66 to 86 centimeters (26.0 to 33.9 inches); olive brown (2.5Y 4/4) gravelly fine sandy loam; moderate medium platy structure; firm, nonsticky, nonplastic; 0.5 fine pores; dark brown (7.5YR 3/3) iron-manganese concretions; 25 percent by volume 20-48-75 millimeter metamorphic, unspecified fragments. Lab sample # 40A03351. A few fine glazed pores occur both on the surface and interior of the peds.
    2Bx1—86 to 122 centimeters (33.9 to 48.0 inches); gravelly loam; weak medium platy structure; firm, nonsticky, nonplastic; olive brown (2.5Y 4/4) and grayish brown (2.5Y 5/2); 25 percent by volume 20-48-75 millimeter metamorphic, unspecified fragments. Lab sample # 40A03352. 2.5Y 5/2 surfaced, vertical cracks (polygon faces?) occur at distances of about 2-3 feet. These have a 1/4 inch wide 7.5YR 4/4 border. The cracks are not very distinct in this horizon but become more so in the horizon below. Fine glazed pores common on exterior of plates with fewer on the interior.
    2Bx2—122 to 163 centimeters (48.0 to 64.2 inches); gravelly loam; weak medium platy structure; firm, nonsticky, nonplastic; 25 percent by volume 20-48-75 millimeter metamorphic, unspecified fragments. Lab sample # 40A03353. Essentially like the horizon above but perhaps more distinctly mottled and with vertical cracks slightly more prominent. These cracks are not evident below five feet. Pores are less evident below 5 or 6 feet but the consistence and structure seem to continue unchanged to the unoxidized till at 13 1/2 feet. The 2.5Y-5Y 5/2 gray mottling also disappears below six feet.
    3Cd1—320 to 381 centimeters (126.0 to 150.0 inches); gray (5Y 5/1) and yellowish red (5YR 4/6) gravelly fine sandy loam; weak very coarse platy structure; very firm, slightly sticky, moderately plastic; nonflat indurated 30-52-75 millimeter unspecified fragments and nonflat indurated 75-162-250 millimeter unspecified fragments and nonflat indurated 250-290-330 millimeter unspecified fragments and nonflat weakly coherent cemented 25-50-75 millimeter unspecified fragments and nonflat weakly coherent cemented 75-88-102 millimeter unspecified fragments. Lab sample # 40A03354. Very firm in place and difficult to remove with a shovel even from the side of the pit; coarse skeletons occur mostly in the 1.2-13 inch diameter range, but with stones or boulders at distances of 5 or 6 feet. Brown, soft, weathered finely micaceous ghosts 1-4 inches in diameter occur at distances of from 1 to 4 feet.
    3Cd2—366 to 396 centimeters (144.1 to 155.9 inches); gray (5Y 5/1) and yellowish red (5YR 4/6) gravelly fine sandy loam; weak very coarse platy structure; very firm, slightly sticky, moderately plastic; nonflat indurated 30-52-75 millimeter unspecified fragments and nonflat indurated 75-162-250 millimeter unspecified fragments and nonflat indurated 250-290-330 millimeter unspecified fragments and nonflat weakly coherent cemented 25-50-75 millimeter unspecified fragments and nonflat weakly coherent cemented 75-88-102 millimeter unspecified fragments. Lab sample # 40A03355. Oxidized 12-13 feet (6-18 inches above contact). Like the horizon above but just above the junction.
    3Cd3—442 to 457 centimeters (174.0 to 179.9 inches); dark gray (5Y 4/1) sandy clay loam; weak very coarse platy structure; very firm, slightly sticky, moderately plastic; nonflat indurated 30-52-75 millimeter unspecified fragments and nonflat indurated 75-162-250 millimeter unspecified fragments and nonflat indurated 250-290-330 millimeter unspecified fragments and nonflat weakly coherent cemented 25-50-75 millimeter unspecified fragments and nonflat weakly coherent cemented 75-88-102 millimeter unspecified fragments. Lab sample # 40A03356. Unoxidized 14-1/2 - 15 feet (6-18 inches below contact). Contains about the same coarse skeleton as the horizons above the junction; plates are about 4 x 6 x 2 and lap over one another.
    3Cd4—503 to 533 centimeters (198.0 to 209.8 inches); sandy clay loam; coarse platy structure; nonflat indurated 75-162-250 millimeter unspecified fragments and nonflat indurated 250-290-330 millimeter unspecified fragments and nonflat weakly coherent cemented 25-50-75 millimeter unspecified fragments and nonflat weakly coherent cemented 75-88-102 millimeter unspecified fragments and nonflat indurated 30-52-75 millimeter unspecified fragments. Lab sample # 40A03357. Unoxidized 16-1/2 - 17-1/2 feet (36-48 inches below contact). Like the above except perhaps with coarse platy structure. Noncalcareous.
