This dataset is a polygon coverage of minable thickness for the Pond Creek coal zone in Kentucky, West Virginia, and Virginia. The coverage was created by gridding 4,391 points and contouring the grid with 1.17-ft intervals. The polygons have elevation values halfway between the bounding contour arc values. This dataset honors data submitted for the asessment from the Kentucky Geological Survey; therefore contour lines may not match across State lines (see Process Steps). 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.
