Ap--0 to 35 centimeters (0.0 to 13.8 inches); brown (10YR 4/3) loamy sand; weak medium subangular blocky structure, and weak coarse subangular blocky structure; subrounded 2- to 75-millimeter unspecified fragments; common very fine and few fine roots; abrupt smooth boundary.
Bw1--35 to 56 centimeters (13.8 to 22.0 inches); light olive brown (2.5Y 5/6) loamy sand; massive; subrounded 2- to 75-millimeter unspecified fragments; common very fine roots; clear wavy boundary.
Bw2--56 to 76 centimeters (22.0 to 29.9 inches); light olive brown (2.5Y 5/4) loamy fine sand; massive; few very fine roots; clear wavy boundary.
BC--76 to 94 centimeters (29.9 to 37.0 inches); 80 percent light yellowish brown (2.5Y 6/3) and 20 percent light brownish gray (2.5Y 6/2) loamy fine sand, silt loam; massive; few very fine roots; clear wavy boundary.
C1--94 to 178 centimeters (37.0 to 70.1 inches); sand, coarse sand; single grain; subrounded 2- to 75-millimeter unspecified fragments; abrupt wavy boundary. Horizon Notes: Unable to determine color – individual sand grains, mixed lithology (approx 30 % dark shales, 50 % quartz).
2C--178 to 203 centimeters (70.1 to 79.9 inches); 95 percent olive gray (5Y 5/2) and 5 percent light olive brown (2.5Y 5/6) silt loam (high chrom colors are associated with textural breaks between plates); weak fine platy structure, and weak medium platy structure (geologic); 1 percent irregular weakly cemented light olive brown (2.5Y 5/6), moist, iron-manganese concretions around rock fragments. Horizon notes: Silty textures continue to 85 inches, below 85 inches is stratified LS and SIL textures to 130 inches then SIL to 160 inches.
