HARTLETON SERIES

TAXONOMIC CLASS: Loamy-skeletal, mixed, active, mesic Typic Hapludults

TYPICAL PEDON: Hartleton channery silt loam in a cultivated field. (Colors are for moist soil unless otherwise indicated.)

Ap-- 0 to 20 centimeters (0 to 8 inches); dark grayish brown (10YR 4/2) channery silt loam; weak fine granular structure; friable, nonsticky, slightly plastic; many fine roots; 30 percent rock fragments; moderately acid; abrupt smooth boundary. Combined thickness of the Ap horizon is 12 to 25 centimeters (5 to 10 inches) thick.

Bt1-- 20 to 38 centimeters (8 to 15 inches); yellowish brown (10YR 5/6) very channery silt loam; moderate medium subangular blocky structure; friable, slightly sticky, slightly plastic; few fine roots; few distinct clay films on all faces of peds; 40 percent rock fragments; moderately acid; clear wavy boundary.

Bt2-- 38 to 66 centimeters (15 to 26 inches); yellowish brown (10YR 5/6) very channery silt loam; moderate medium subangular blocky structure; friable, slightly sticky, slightly plastic; few fine roots; few distinct clay films on all faces of peds; 40 percent rock fragments; moderately acid; clear wavy boundary.

Bt3-- 66 to 84 centimeters (26 to 33 inches); yellowish brown (10YR 5/4) extremely channery loam; weak fine and medium subangular blocky structure; friable, nonsticky, slightly plastic; few fine roots; few faint clay films on all faces of peds; 60 percent rock fragments; strongly acid; gradual wavy boundary. Combined thickness of Bt horizon ranges from 15 to 75 centimeters (6 to 30 inches).

C-- 84 to 117 centimeters (33 to 46 inches); brown (7.5YR 5/4) extremely channery loam; massive; friable, nonsticky, nonplastic; common black coatings on rock fragments; 75 percent rock fragments; strongly acid; clear wavy boundary. Combined thickness of the C horizon ranges from 12 to 50 centimeters (5 to 20 inches thick).

R-- 117 centimeters (46 inches); brown (7.5YR 4/4) fractured sandstone and shale bedrock.
