资源简介：

This dataset is a polygon coverage of counties limited to the extent of the Pond Creek coal zone resource areas and attributed with original resources (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.
