资源简介：
This dataset is a polygon coverage of counties limited to the extent of
the Pittsburgh coal bed resource areas and attributed with original resource
values (millions of short tons) in aggregated reporting categories as described
in USGS Circular 891. The file has been generalized from detailed geologic
coverages found elsewhere in Professional Paper 1625-C.
