    Ap—0 to 15 centimeters (0.0 to 5.9 inches); dark grayish brown (10YR 4/2), light brownish gray (10YR 6/2), dry; silt loam; strong fine granular structure; very friable; many (10.0) fine roots throughout; fragments; slightly acid, pH 6.2, hellige-truog; clear smooth boundary. Lab sample # MU011056
    BA—15 to 28 centimeters (5.9 to 11.0 inches); yellowish brown (10YR 5/4), very pale brown (10YR 7/3), dry; silt loam; moderate fine subangular blocky structure; very friable; common (3.0) fine roots throughout; fragments; slightly acid, pH 6.2, hellige-truog; gradual wavy boundary. Lab sample # MU011057. Pedon horizon designation was changed to BA because there was a slight increase in clay from the A, and so could not be considered a BE, but the clay increase was not enough for a Bt.
    Bt—28 to 53 centimeters (11.0 to 20.9 inches); dark yellowish brown (10YR 4/4) gravelly silty clay loam; moderate fine subangular blocky structure; friable; common (3.0) fine roots throughout; 10 percent distinct clay films on faces of peds; 15 percent by volume 2-20-75 millimeter limestone, cherty fragments; very strongly acid, pH 4.8, hellige-truog; abrupt wavy boundary. Lab sample # MU011058
    2Btx1—53 to 61 centimeters (20.9 to 24.0 inches); yellowish brown (10YR 5/4) cobbly silt loam; 1 percent strong brown (7.5YR 5/6) fine distinct mottles; weak fine platy parts to weak very fine platy structure; very firm; brittle; common (3.0) very fine roots throughout and common (3.0) fine roots throughout; 10 percent distinct clay films on all faces of peds; 10 percent by volume 75-150-250 millimeter limestone, cherty fragments and 15 percent by volume 2-20-75 millimeter limestone, cherty fragments; strongly acid, pH 5.5, hellige-truog; gradual wavy boundary. Lab sample # MU011059. Pedon horizon designation was changed from a 2E to a 2Btx1 because this horizon and the original 2Btx were combined for the series description in the Cedar and Dade Counties manuscripts. These could not be combined in NASIS, as lab data was taken on each horizon, and so was given 2Btx1 and 2Btx2 designations.
    2Btx2—61 to 76 centimeters (24.0 to 29.9 inches); grayish brown (10YR 5/2) and strong brown (7.5YR 5/6) very gravelly silty clay loam; strong very coarse prismatic parts to weak thin platy structure; very firm; brittle; many (10.0) very fine and fine roots top of horizon and few (0.5) fine roots in cracks; 10 percent distinct clay films on all faces of peds; 10 percent fine dark red (2.5YR 3/6) masses of oxidized iron; 10 percent by volume 75-150-250 millimeter limestone, cherty fragments and 30 percent by volume 2-20-75 millimeter limestone, cherty fragments; very strongly acid, pH 4.5, hellige-truog; abrupt wavy boundary. Lab sample # MU011060
    3Bt1—76 to 99 centimeters (29.9 to 39.0 inches); dark red (2.5YR 3/6) gravelly clay; strong fine angular blocky structure; firm; 30 percent distinct clay films on all faces of peds; 10 percent fine brown (7.5YR 5/3) masses of oxidized iron and 10 percent fine reddish yellow (7.5YR 6/6) masses of oxidized iron; 15 percent by volume 2-20-75 millimeter limestone, cherty fragments; very strongly acid, pH 4.5, hellige-truog; gradual wavy boundary. Lab sample # MU011061
    3Bt2—99 to 152 centimeters (39.0 to 59.8 inches); dark red (2.5YR 3/6) gravelly clay; strong fine angular blocky structure; firm; 30 percent distinct clay films on all faces of peds; 10 percent fine brown (7.5YR 5/4) masses of oxidized iron and 10 percent fine strong brown (7.5YR 5/6) masses of oxidized iron; 15 percent by volume 2-20-75 millimeter limestone, cherty fragments; very strongly acid, pH 4.7, hellige-truog. Lab sample # MU011062
