CA--0 to 10 centimeters (0.0 to 3.9 inches); olive gray (5Y 4/2) interior, loamy sand; massive; very friable, nonsticky, nonplastic; nonfluid; low penetration resistance; low excavation difficulty; negative reaction to alpha-alpha' dipyridyl; clear boundary.

Ab--10 to 21 centimeters (3.9 to 8.3 inches); very dark gray (5Y 3/1) interior, loamy sand; massive; very friable, nonsticky, nonplastic; nonfluid; low penetration resistance; low excavation difficulty; common fine roots throughout; negative reaction to alpha-alpha' dipyridyl; clear boundary.

Cg--21 to 41 centimeters (8.3 to 16.1 inches); 95 percent olive gray (5Y 5/2) interior, very fine sandy loam; massive; friable, nonsticky, nonplastic; nonfluid; low penetration resistance; low excavation difficulty; negative reaction to alpha-alpha' dipyridyl; 1 cm horizontal bands of A material mixing 5Y3/1; abrupt boundary.

2Cg1--41 to 68 centimeters (16.1 to 26.8 inches); 95 percent light brownish gray (2.5Y 6/2) interior, loamy coarse sand; single grain; moderate excavation difficulty; 5 percent coarse prominent irregular iron concretions with clear boundaries in matrix; 20 percent nonflat subangular indurated mixed rock fragments; clear boundary.

2Cg2--68 to 105 centimeters (26.8 to 41.3 inches); light brownish gray (2.5Y 6/2) interior, coarse sand; single grain; loose, nonsticky, nonplastic; nonfluid; moderate penetration resistance; moderate excavation difficulty; 40 percent nonflat subangular indurated 2- to 6-millimeter mixed rock fragments; negative reaction to alpha-alpha' dipyridyl; clear boundary.
