This dataset is a polygon coverage of structure contours (elevation) for the Pond Creek coal zone in Kentucky, West Virginia, and Virginia. The surface was created by gridding information from 137,355 points and contouring the grid into 100-ft intervals. Many of the points were derived from existing structure contoure maps obtained from Kentucky and West Virgina. In Virginia, data were searched from the StratiFact database created from the National Coal Resource Data System (NCRDS). Data from specific quadrangles in the StratiFact database from the West Virginia Geological and Economic Survey were also searched. The grid was created in EarthVision, was contoured and imported to ARC/INFO as polygons using an AML. State line discrepancies were expected and rectified. Offsets existed because State contours were created from more local, not regional data sets. The data from the West Virginia Geological and Economic Survey are not final in nature, as correlation of the beds in this stratigraphic sequence is ongoing. Thus the nature of this coverage is necessarily provisional. The polygons have elevation values halfway between values of the bounding contour arc values, therefore the polygon values will end in '50'. This map is one of many Geographic Information System (GIS) products of the National Coal Assessment that is being conducted by the U.S. Geological Survey in cooperation with State geological surveys and other Federal and State agencies. The Middle Pennsylvanian Pottsville Group Pond Creek coal is an important resource in the Central Appalachian Basin coal region and has been mined for the last one hundred years. The Pond Creek coal is most commonly referred to as the Lower Elkhorn in Kentucky, the Imboden in Virginia, and the Eagle in West Virginia. The Pond Creek coal and its equivalent beds occur within a zone of coal-bearing rocks that contain a number of distinct coals. This resource model for the Pond Creek coal must be considered provisional, because the correlation of the zone continues to be evaluated in West Virginia.
