    A2—0 to 8 centimeters (0.0 to 3.1 inches); dark grayish brown (10YR 4/2), light brownish gray (10YR 6/2), dry; silt loam; strong very fine granular structure; soft, very friable; fragments; neutral, pH 6.8, unspecified; abrupt smooth boundary. Lab sample # 40A29602. This horizon grades from a silt loam to a silty clay loam; the bottom 1/4 to 1/2 inch has strong very fine platy structure coating the tops of the columns of the B2.
    B2t—8 to 25 centimeters (3.1 to 9.8 inches); dark brown (10YR 3/3), brown (10YR 4/3), dry; clay; moderate medium columnar parts to strong fine angular blocky structure; very hard, very firm; 21.0 roots; clay films on faces of peds; fragments; slightly alkaline, pH 7.6, unspecified; abrupt wavy boundary. Lab sample # 40A29603. Top 2 inches have darker staining on outside of peds; columns are coated with bleached fine sand grains.; continuous - phpvsfiid 196760; continuous - phpvsfiid 196760
    B2ca—25 to 33 centimeters (9.8 to 13.0 inches); brown (10YR 4/3), brown (10YR 5/3), dry; silty clay; moderate medium prismatic parts to moderate and strong fine angular blocky structure; hard, firm; 21.0 roots; clay films on faces of peds; fragments; strong effervescence; strongly alkaline, pH 8.6, unspecified; clear smooth boundary. Lab sample # 40A29604. patchy - phpvsfiid 196748; patchy - phpvsfiid 196748
    B31ca—33 to 51 centimeters (13.0 to 20.1 inches); brown (10YR 5/3), pale brown (10YR 6/3), dry; silty clay loam; moderate medium prismatic parts to moderate medium subangular blocky, and angular blocky structure; hard, friable; 21.0 roots; clay films on vertical faces of peds; 3 percent medium carbonate concretions; fragments; violent effervescence; strongly alkaline, pH 9.0, unspecified; gradual smooth boundary. Lab sample # 40A29605. patchy - phpvsfiid 196749; patchy - phpvsfiid 196749
    B32ca—51 to 74 centimeters (20.1 to 29.1 inches); brown (10YR 5/3), pale brown (10YR 6/3), dry; silty clay loam; weak medium prismatic parts to weak medium subangular blocky structure; hard, friable; 21.0 roots; 10 percent clay films on vertical faces of peds; 3 percent medium carbonate concretions; fragments; violent effervescence; gradual smooth boundary. Lab sample # 40A29606. Many roots readily penetrate peds; small holes less than one millimeter in diameter are common; lime concretions are common medium and faint.
    C1—74 to 102 centimeters (29.1 to 40.2 inches); brown (10YR 5/3), pale brown (10YR 6/3), dry; silt loam; weak coarse prismatic structure; slightly hard, friable; 3.0 roots; fragments; violent effervescence; diffuse boundary. Lab sample # 40A29607. But many holes less than one millimeter in diameter.
    C2—102 to 140 centimeters (40.2 to 55.1 inches); brown (10YR 5/3), pale brown (10YR 6/3), dry; silt loam; massive; soft, very friable; 0.1 roots; fragments; violent effervescence; abrupt boundary. Lab sample # 40A29608. But many holes less than one millimeter in diameter.
    C3—140 to 173 centimeters (55.1 to 68.1 inches); brown (10YR 5/3), pale brown (10YR 6/3), dry; silt loam; massive; soft, very friable; 0.0 roots; fragments; violent effervescence. Lab sample # 40A29609. But small holes continue.
