Final unioned polygon coverages and shapefiles used to calculate coal resources of the A through G coal zones, Danforth Hills coal field, northwestern Colorado. Danafing was used for the A coal zone; Danbfing was used for the B coal zone; etc. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, lease boundaries, overburden, and coal thickness categories. The final coverages were clipped to the resource areas for each coal zone, which are described in the metadata files for the *_bnd coverages.
