This shapefile and coverage includes anticlines and synclines in the Yampa coal field captured at 1 : 500,000 scale.
These are shapefiles and final unioned polygon coverages used to calculate coal resources of the A through D coal zones, Yampa coal field, northwestern Colorado. Yamafing was used for the A coal zone, yambfing 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, leased areas, net coal thickness categories, and overburden categories. The final unioned coverage for each coal zone, was clipped by the resource boundary polygon of each coal zone. These polygons are described in the metadata files for the yam_bnd coverages.
