This is a point file that contains data for coal and other stratigraphic horizons in in the Calico and A-sequences of the Straight Cliffs Formation (Upper Cretaceous) east of 112 degrees of longitude in the Kaiparowits Plateau. The item map# is the number of the data point on the index map (Figure A, Plate 1). The map# that refers to a record in the data table (Appendix 1) in Hettinger and others, chap. T. Buffers were drawn at a three-mile distance from data points in this coverage to create the reliability coverage.

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 polygon coverage that represents areas underlain by the coal-bearing Calico and A-sequences of the Straight Cliffs Formation east of 112 degrees of longitude. It differentiates between areas that contain the entire coal-bearing interval and areas where the coal-bearing strata are partially eroded. The outermost polygon defines the base of the Calico and A-sequences. The inner polygon shows where the complete coal-bearing interval is preserved. The area between the outer and inner polygon shows where the coal-bearing rocks are partially eroded. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.

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 polygon coverage and shapefile that defines areas that are underlain by the Osiris Tuff and Wasatch Fm. (Tert.), Pine Hollow Fm. (Tert.?), Canaan Peak Fm. (Tert.? and Cret.), and the Kaiparowits and Wahweap Fms. (Cret). east of 112 degrees of longitude in the Kaiparowits Plateau, southern Utah. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.

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.
thumbnail
This is a polygon coverage of isopachs of the combined thickness of the Calico and A-sequences in the Kaiparowits Plateau study area. The outside polygon defines the base of the John Henry Member of the Straight Cliffs Formation east of 112 degrees of longitude. The polygon includes areas where the Calico and A-sequences have been partially eroded. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.
thumbnail
This is a shapefile and unioned polygon ownership coverage used to calculate coal resources of the A through D coal zones, Yampa coal field, northwestern Colorado. Polygons that have been combined include counties, 7.5' quadrangles, townships, surface and coal ownership. This ownership coverage was clipped by the largest resource boundary polygon--that of the A coal zone.
thumbnail
This is a shapefile and coverage that outlines the area underlain by coals in the lower Blackhawk Formation, southern Wasatch Plateau coal assessment area. The polygons delimit the area within which resources were calculated and reported.

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.
