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.

These are shapefiles and ARC/INFO polygon coverages showing the isopachs of total net coal in beds greater than or equal to 1.2' thick for the A through G coal zones, Danforth Hills coal field. The coverage danathkg is the isopach coverage for the A coal zone; danbthkg is for the B coal zone, and so on.
thumbnail
These are shapefiles and coverages that represent areas of combined State and Federal coal leases and mined-out areas in the Yampa coal field. Yamaleasg contains polygons for which resources were not calculated for the A coal zone. Yambleasg contains polygons for which resources were not calculated for the B coal zone, etc.

This shapefile includes anticlines and synclines of the Lower White River coal field. Nominal map scale is 500,000. The original digital source data for this shapefile was the digital geologic map of Colorado.

These are shapefiles and ARC/INFO polygon coverages showing the isopachs of total net coal in beds greater than or equal to 1.2' thick for the A, B, C, and D coal zones in the Williams Fork Formation, Yampa coal field, northwestern Colorado. YAMATHKG is for the A coal zone, YAMBTHKG is for the B coal zone, etc.
thumbnail
These are shapefiles and ARC/INFO coverages that outline the areas within which coal resources are calculated and reported for the A/B through G coal zones, Danforth Hills coal field. The shapefile DANABBNDG is the defining resource polygon for the A and B coal zones; DANCbndg is the defining resource polygon for the C coal zone, and so on.
thumbnail
These are shape files of final unioned polygon coverages used to calculate coal resources of the B and D coal zones, Lower White River coal field, Deserado assessment area, northwestern Colorado. Desbfing was used for the B coal zone; Desdfing was used for the D coal zone. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, lease area, 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 des_bnd coverages.
thumbnail
Land status and Federal mineral ownership in the Danforth Hills coal field, northwestern Colorado. Polygons that make up the ownership coverage include counties, 7.5' quadrangles, townships, surface and coal ownership. The ownership coverage was clipped to the base of the A and B coal zones or top of the Trout Creek Sandstone Mbr.
