Latham silt loam, in a pastured area of Dormont-Latham complex, 15 to 25 percent
slopes, in Wayne County, West Virginia; about 300 yards east-southeast of the
intersection of West Virginia State Routes 152 and 37 and about 200 yards southeast
of the confluence of Trace Fork and the West Fork of Twelvepole Creek; USGS
Wayne topographic quadrangle; lat. 38 degrees 10 minutes 35 seconds N. and
long. 82 degrees 28 minutes 35 seconds W.
A—0 to 4 inches; dark brown (10YR 3/3) silt loam, light yellowish brown (10YR 6/4)
dry; moderate fine and medium granular structure; very friable; many fine and
medium roots; 5 percent siltstone and shale channers; slightly acid; abrupt
smooth boundary.
BA—4 to 7 inches; yellowish brown (10YR 5/4) channery silt loam; moderate medium
granular structure; friable; many fine and medium roots; 20 percent siltstone and
shale channers; slightly acid; clear wavy boundary.
Bt1—7 to 16 inches; yellowish brown (10YR 5/6) channery silty clay loam; moderate
fine and medium subangular blocky structure; friable; common fine and medium
roots; many distinct clay films on faces of peds; 15 percent siltstone and shale
channers; very strongly acid; clear smooth boundary.
Bt2—16 to 23 inches; light yellowish brown (2.5Y 6/4) channery silty clay; many fine
and medium light gray (2.5Y 7/2) redox depletions; weak fine and medium
subangular blocky structure; firm; common fine roots; many distinct clay films on
faces of peds; 25 percent siltstone and shale channers; very strongly acid; clear
wavy boundary.
Bt3—23 to 29 inches; yellowish brown (10YR 5/6) channery silty clay; many medium
and coarse light gray (10YR 7/1) redox depletions; weak medium subangular
blocky structure; firm; few fine roots; few or common distinct clay films on faces of
peds; 30 percent siltstone and shale channers; very strongly acid; clear wavy
boundary.
C—29 to 34 inches; yellowish brown (10YR 5/6) channery silty clay; many medium
and coarse light gray (10YR 7/1) redox depletions; massive; firm; 30 percent
siltstone and shale channers; very strongly acid; abrupt wavy boundary.
Cr—34 to 39 inches; soft interbedded acid gray shale and siltstone bedrock.
