These are shapefiles and ARC/INFO coverages of coal fields and coal-bearing formations in the Colorado Plateau. These GIS layers were created by combining numerous ARC/INFO coverages created for the Colorado Plateau coal assessment. The coal field outlines are approximate boundaries based on criteria provided below under Data Quality Information, Process Steps. These coal field outlines may not overlap exactly with other published coal field boundaries or with criteria used in the geochemistry data. We used existing polygons taken from numerous digital geologic maps, as described in Process Steps, but did not use overburden cutoffs.

These are shapefiles and coverages of final unioned polygon coverages used to calculate coal resources of the Cameo/Fairfield coal group east of 107 deg 15' longitude, and the Cameo/Wheeler, South Canyon, and Coal Ridge coal zones west of 107 deg 15' longitude in the southern Piceance Basin, northwestern Colorado. Pscbfing was used for the area east of 107 deg 15' longitude; pscwfing was used for the Cameo/Wheeler coal zone; psscfing was used for the South Canyon coal zone; pscrfing was used for the Coal Ridge coal zone. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, reliability, and, overburden. The final unioned coverage for each coal...

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.
