Coal Seams Map

This map displays coal fields by coal type in the Big Sky Region. Deep unminable coal seams may prove to be particularly suitable sinks for CO₂ injection and have been analyzed by BSCSP to estimate the potential CO₂ storage capacities. The Powder River and Green River basins of the Big Sky region contain significant coal and coal-bed methane resources. These resources are important economically for power generation. However, there is significant CO₂ storage potential within coal seams that are too deep, or too thin to be economically viable as mineable resources.

Data sources: 1991 The Geological Society of America, Inc.; coal capacity estimates were calculated by BSCSP.
