Estimated resources of non-leased federal coal, Powder River Basin, Montana and Wyoming
V. A. Trent
1986, Miscellaneous Field Studies Map 1887
Maps are generated by combining digital ownership data with geologic resource estimates and other spatial coal data in a geographic information system (GIS). For example, we merged the newly compiled Federal coal ownership files with resource calculations from the 1970's for the Powder River Basin (Trent, 1986). For the first...
