    AP—0 to 23 centimeters (0.0 to 9.1 inches); very dark grayish brown (10YR 3/2) loam; weak medium granular structure; friable; 21.0 roots; fragments; abrupt smooth boundary. Lab sample # 40A04163. Few small iron-impregnated volcanic fragments.
    B21T—23 to 48 centimeters (9.1 to 18.9 inches); yellowish brown (10YR 5/6) clay; 1 percent yellowish red (5YR 5/8) medium faint mottles; moderate medium subangular blocky structure; moderately sticky, moderately plastic; 0.5 roots; fragments; clear smooth boundary. Lab sample # 40A04164. Streaks of very dark grayish brown (10YR 3/2) from Ap; many iron-impregnated volcanic fragments.
    B22T—48 to 76 centimeters (18.9 to 29.9 inches); red (2.5YR 4/8) clay; 1 percent yellowish brown (10YR 5/8) medium faint mottles; moderate medium subangular blocky structure; moderately sticky, moderately plastic; 0.5 roots; clay films on faces of peds; fragments; clear smooth boundary. Lab sample # 40A04165. Many iron-impregnated volcanic fragments.
    C1—76 to 102 centimeters (29.9 to 40.2 inches); red (2.5YR 4/8) clay; 3 percent white (7.5YR 8/1) medium prominent and 3 percent yellowish brown (10YR 5/8) medium prominent mottles; massive; moderately sticky, moderately plastic; fragments; gradual irregular boundary. Lab sample # 40A04166
    C2CS—102 to 132 centimeters (40.2 to 52.0 inches); strong brown (7.5YR 5/8) and white (7.5YR 8/1) clay; massive; moderately sticky, moderately plastic; 21 percent gypsum crystals, unspecified; fragments. Lab sample # 40A04167. Zone of concentration of gypsum crystals. The high concentration of crystals is unusual, although adjacent areas of this soil appear to have disseminated gypsum.
