This is a coverage of the Colorado Plateau coal assessment study area. The study area outline was drawn on the county lines that most closely outline the coal-bearing rocks in the Colorado Plateau Region. The county outlines originate from a national coverage for which lines were extracted from U.S. Census 1990 TIGER/line files using an AML program written by Nebert, D., and Negri, M., USGS-Water Resources Division (WRD), running on two Data General 6220 servers.

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.

This is a polygon coverage of the structure contours of the Calico sequence boundary in the Kaiparowits Plateau, southern Utah. Sequence boundary elevations are based on 166 drill sites. The Calico sequence boundary occurs from 50-100 ft below the base of the John Henry Member, therefore an inferred elevation of the sequence boundary was used at numerous locations along the outcrop where the John Henry Member was mapped. The outside polygon defines the base of the coal-bearing Calico and A-sequences of the Straight Cliffs Formation east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.

This is a line coverage of the geologic structural features within the Kaiparowits Plateau. Structural features include synclines, anticlines, folds and faults; and are shown in Hettinger and others, chap. T. Faults and fold axes are located along the Earth's surface. This does not imply where they are located in the subsurface.

This is a polygon coverage of the outcrop of the John Henry Member of the Straight Cliffs Formation east of 112 degrees of longitude in the Kaiparowits Plateau, southern Utah. This polygon was used to represent the areas underlain by the Calico Sequence boundary. This polygon was also used as the "outside" clipping polygon for several of the data layers including the overburden and isopach coverages. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.

This is a polygon coverage and shapefile that contains undivided Upper Cretaceous rocks that include (in descending order) the Smoky Hollow and Tibbet Canyon Mbs. of the Straight Cliffs Fm., and the Tropic Shale and Dakota Fm. This coverage shows where these rocks are exposed along the outcrop and are buried in the subsurface in the Kaiparowits Plateau study area, southern Utah. The base of the Dakota Fm. was used to define the Kaiparowits Plateau for areas east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and volcanic rocks of Tertiary age.

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.

This is a coverage that shows areas in the Kaiparowits Plateau where geologic conditions in the Calico and A-sequences are more favorable for current underground mining technology (Hettinger and other, chap. T). This coverage contains numerous attributes of information. It was compiled by computing the geometric intersection of nine polygon coverages using the ARC/INFO UNION command. This coverage is characterized as being a GUIDE TO WHERE THE MORE FAVORABLE COAL AREAS ARE LIKELY TO BE for current underground mining technology: areas where coal beds in the Calico and A-sequences are greater than 3.5 feet thick, less than 3,000 feet deep, and inclined by less than 12 degrees, as described in Hettinger and others,...

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.

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.

These are shapefiles and polygon coverages that contain numerous attributes of information on coal in the Calico and A-sequences of the Upper Cretaceous Straight Cliffs Formation in the Kaiparowits Plateau study area in southern Utah. These layers were derived from a "union" process of combining numerous polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick. The outside polygon defines the base of the coal-bearing Calico and A-sequences east of 112 degrees of longitude. The northern boundary is delineated by...

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 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 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.
