This ArcView shapefile contains a representation of the Hanna 79 coal zone study limit boundary in the Hanna coalfield, Hanna Basin, Wyoming. This shapefile was created specifically for the National Coal Resource Assessment in the Northern Rocky Mountains and Great Plains Region.

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.
thumbnail
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.

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.

This ArcView shapefile contains a representation of the Ferris 25 coal zone study limit in the Ferris coalfield, Hanna Basin, Wyoming. This theme was created specifically for the National Coal Resource Assessment in the Northern Rocky Mountains and Great Plains Region.

This ArcView shapefile contains a representation of the Hanna 81 coal zone study limit boundary in the Hanna coalfield, Hanna Basin, Wyoming. This shapefile was created specifically for the National Coal Resource Assessment in the Northern Rocky Mountains and Great Plains Region.
thumbnail
This ArcView shapefile contains a polygon representation of the land use/land cover in the Hanna and Carbon Basins, Wyoming. This shapefile was created as part of the National Coal resource assessment in the Northern Rocky Mountains and Great Plains Region, and can be shown in relation to other relevant themes of this area.
thumbnail
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.
thumbnail
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.
thumbnail
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.

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,...
