    A2—0 to 8 centimeters (0.0 to 3.1 inches); grayish brown (10YR 5/2), white (10YR 8/1), dry; fine sandy loam; weak coarse platy parts to moderate fine granular structure; soft, very friable; fragments; noneffervescent; clear smooth boundary. Lab sample # 40A26579
    B2t—8 to 23 centimeters (3.1 to 9.1 inches); dark grayish brown (10YR 4/2), grayish brown (10YR 5/2), dry; silty clay; moderate medium columnar parts to strong medium angular blocky structure; very hard, very firm; 30 percent clay films; fragments; noneffervescent; abrupt smooth boundary. Lab sample # 40A26580. structural aggregates have well rounded caps.
    B3sa—23 to 38 centimeters (9.1 to 15.0 inches); light olive brown (2.5Y 5/3), light yellowish brown (2.5Y 6/3), dry; silty clay loam; moderate coarse prismatic parts to moderate coarse angular blocky structure; very hard, firm; 1 percent carbonate concretions; fragments; strong effervescence; gradual irregular boundary. Lab sample # 40A26581. the horizon contains a few small calcium carbonate concretions.
    C1sa—38 to 58 centimeters (15.0 to 22.8 inches); light olive brown (2.5Y 5/3), light brownish gray (2.5Y 6/2), dry; clay loam; weak coarse angular blocky structure; very hard, firm; carbonate masses and 1 percent carbonate concretions; fragments; strong effervescence; gradual smooth boundary. Lab sample # 40A26582. the horizon contains much calcium carbonate and other salts; calcium carbonate chiefly as lime flour but with a few concretions.
    C2sa—58 to 76 centimeters (22.8 to 29.9 inches); olive gray (5Y 5/2), light olive gray (5Y 6/2), dry; sandy clay loam; massive, and weak coarse subangular blocky; very hard, firm; carbonate concretions and carbonate masses and gypsum crystals, unspecified; fragments; strong effervescence; gradual smooth boundary. Lab sample # 40A26583. horizon contains much accumulated calcium carbonate and other salts; calcium carbonate chiefly as lime flour; there are a few concretions believed to be calcium sulfate in the lower part.
    C3sa—76 to 104 centimeters (29.9 to 40.9 inches); pale olive (5Y 6/3), pale olive (5Y 6/3), dry; sandy clay loam; massive; very hard, firm; fragments; strong effervescence. Lab sample # 40A26584. horizon contains some visible calcium carbonate and other salts but much less than the horizons above; this horizon consists principally of reworked clayey alluvium washed down the sides of old terrace levels.
