All mining lease boundaries found in the Powder River Basin. This data layer has many overlapping polygon features and is thus more applicable if used as Arc/Info regions. Each region is attributed relating to the name of the coal mine utilizing the leased area. The data layer was originally produced by the Bureau of Land Management and distributed in an ASCII text format which was then converted into a GIS layer.

Coal croplines found in the Powder River Basin, 1:24000 scale. Coal cropline is the exposed coal seam due to erosion and tectonics. Each linear feature is attributed with reference to the name of the coal seam that is exposed. The data were originally produced by digitizing photointerpreted coal cropline features off of 1:24,000 USGS quadrangles.

This data set was developed from a Bureau of Land Management database containing information on coal thickness from core samples, converted into a spatial database using kriging techniques. The data set covers the Little Thunder Creek watershed in the Powder River Basin, Wyoming. Each polygon is attributed with reference to a range of thickness describing the coal seam (measured in feet).

Clinker regions found in the Powder River Basin, 1:24000-scale. Clinker is baked and fused geologic material generated during the combustion of a coal seam. Each area is attributed with reference to the name of the coal seam responsible for producing the clinker. The data were originally produced by digitizing photointerpreted clinker polygons off of 1:24,000 USGS quadrangles.
