    Btk—76 to 94 centimeters (29.9 to 37.0 inches); very dark grayish brown (10YR 3/2), grayish brown (10YR 5/2), dry; loam; weak medium prismatic parts to weak medium subangular blocky structure; slightly hard, very friable, slightly sticky, moderately plastic; moderate permeability; 10 percent clay films on faces of peds; 3 percent carbonate concretions; fragments; strong effervescence; moderately alkaline, pH 8.2, unspecified; gradual wavy boundary. Lab sample # 40A24294. This is a weak ca horizon with some small lime carbonate concretions.
    BCk—94 to 152 centimeters (37.0 to 59.8 inches); grayish brown (2.5Y 5/2), light brownish gray (2.5Y 6/2), dry; loam; slightly hard, very friable, nonsticky, slightly plastic; moderate permeability; carbonate coats on bottom of rock fragments; 3 percent noncoherent cemented carbonate concretions and gypsum threads and 5 percent irregular carbonate masses and 5 percent threadlike carbonate masses; fragments; strong effervescence; moderately alkaline, pH 8.2, unspecified.
