资源简介：
This dataset is a polygon coverage of counties limited to the extent of
the Pocahontas No. 3 coal bed resource areas. The eastern limit of the coal
bed is along the Allegheny structural front, where the bed is either folded
to vertical, overturned to the northwest, or covered by thrust sheets in the
western part of the Valley and Ridge Province. The western limit of minable
coal is in the subsurface and was selected at the 14-inch isoline.
The file has been generalized from detailed geologic
coverages found elsewhere in Professional Paper 1625-C.
