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 ARC/INFO polygon coverages showing the isopachs of total net coal in beds greater than or equal to 1 ft thick for the Cameo/Fairfield coal group and for the Cameo/Wheeler, South Canyon, and Coal Ridge coal zones, southern Piceance Basin coal assessment area. Also included are isopachs of total net coal in beds 1-2.3 ft thick, 2.3-3.5, 3.5-7.0, and 7.0-14, and greater than 14 ft thick in the Cameo/Wheeler coal zone.

This is a shape file and coverage of the top of the Rollins Sandstone Member. It outlines the area underlain by the coal-bearing Cameo/Fairfield coal group in the southern Piceance Basin coal assessment area. Also, it delimits the area within which resources were calculated and reported in the southern Piceance Basin coal assessment area. The polygon was adjusted to match the topography of the DEM.

This is a shapefile and point coverage of 627 data points used in the assessment of coal in the southern Piceance Basin study area. Information in this file includes x, y location and point identifier. Lithologic and stratigraphic data and the geographic distribution of coal are based on our interpretations of geophysical logs from 526 drill holes as well as published lithologic descriptions from 31 coal exploration holes and 70 published stratigraphic sections described from outcrops.

This is a shapefile and coverage of ownership in the southern Piceance Basin coal assessment area, northwestern Colorado. Polygons that make up the coverage include counties, 7.5' quadrangles, townships, and surface and coal ownership. The ownership coverage was clipped by the resource boundary polygon for the coal-bearing Mesaverde Formation and Mesaverde Group which is described in the metadata file for the psmv_bnd coverage.
