    O1—0 to 3 centimeters (0.0 to 1.2 inches); 21.0 fine roots; fragments; abrupt boundary. Not sampled; 3/4 inch layer of undecomposed leaves resting on apparently older 1/4 inch layer of decomposed leaves permeated by many fine roots but retaining original leaf form; a few mouse burrows extend upward to bottom of layer.
    O21—3 to 5 centimeters (1.2 to 2.0 inches); very dark brown (10YR 2/2) and black (10YR 2/1); medium and coarse granular structure; very fine and fine roots; fragments; abrupt smooth boundary. Not sampled; medium and coarse granules hold in an open very porous fabric by dense network of fine and very fine roots.
    O22—5 to 9 centimeters (2.0 to 3.5 inches); black (10YR 2/1) and white (10YR 8/1) fine sand, very fine sand; moderate medium and coarse granular, and weak fine subangular blocky structure; fine roots; fragments; very strongly acid, pH 4.6, bromcresol green. Lab sample # 40A01180. Black (10YR 2/1) organic material with many white (10YR 8/1) fine and very fine sand grains; blocks adhere to a network of fine roots; many 1 inch rodent burrows; much variation in organic: inorganic ratio, in spots approaching A1.
    A2—9 to 13 centimeters (3.5 to 5.1 inches); brown (7.5YR 5/2) loamy very fine sand; weak very fine granular structure; very friable; 21.0 fine and medium roots; fragments; very strongly acid, pH 4.6, bromcresol green; abrupt wavy boundary. Lab sample # 40A01181. No burrows; although some material has been translocated.
    B21—13 to 27 centimeters (5.1 to 10.6 inches); brown (7.5YR 4/4) and dark brown (7.5YR 3/3) and dark yellowish brown (10YR 4/4) very fine sandy loam; weak very fine granular structure; very friable; 5 percent by volume 75-162-250 millimeter unspecified fragments; very strongly acid, pH 4.6, bromcresol green; gradual wavy boundary. Lab sample # 40A01182
    B22—27 to 42 centimeters (10.6 to 16.5 inches); dark yellowish brown (10YR 4/4) very fine sandy loam; weak fine and medium parts to weak very fine granular structure; very friable; 21.0 fine and medium roots; 5 percent by volume 75-162-250 millimeter unspecified fragments; very strongly acid, pH 5.0, bromcresol green; diffuse wavy boundary. Lab sample # 40A01183
    B3—42 to 60 centimeters (16.5 to 23.6 inches); dark yellowish brown (10YR 4/4) very fine sandy loam; weak very fine granular structure; firm; 3.0 fine roots; 3.0 fine tubular pores; 7 percent by volume 75-162-250 millimeter unspecified fragments; strongly acid, pH 5.2, chlorophenol red; abrupt wavy boundary. Lab sample # 40A01184. Breaks out in irregular fine to medium fragments, some being incipient peds which crush to very weak very fine granules.
    IIA'2x—60 to 80 centimeters (23.6 to 31.5 inches); brown (10YR 4/3) crushed and grayish brown (10YR 5/2) broken face loamy fine sand; massive; very firm; 0.1 roots; 3.0 fine tubular pores; light gray (5YR 7/1), moist, silt coats in root channels and/or pores; fragments; strongly acid, pH 5.4, chlorophenol red; clear wavy boundary. Lab sample # 40A01185. Faces decked with (10YR 6/2) (10YR 7/2) sand grains.
    IIB'x—80 to 116 centimeters (31.5 to 45.7 inches); brown (7.5YR 4/2) crushed and brown (7.5YR 4/2) broken face and dark grayish brown (10YR 4/2) broken face fine sandy loam; very coarse platy parts to fine and medium angular blocky structure; firm; 0.5 fine roots; 3.0 fine tubular pores; clay films in root channels and/or pores; 2-39-75 millimeter limestone, unspecified fragments; moderately acid, pH 5.8, chlorophenol red. Lab sample # 40A01186. Broken faces are most cohesive; clean sand grains coat broken 10YR 4/2 faces, absent on 7.5YR 4/2; common dark brown fragments of weathered sandy limestone.
