Most of the coal produced in the PRB supports electric power generation in the United States. Starting in the 1990s, many coalfired power plants switched to subbituminous coal from the PRB—which has relatively low sulfur content—to meet tightening Clean Air Act emission 2003, the Powder River Basin yielded more coal than the Appalachian coal basins in the eastern United States.

The Powder River Basin. The Powder River Basin is a geologic structural basin in southeast Montana and northeast Wyoming, about 120 miles (190 km) east to west and 200 miles (320 km) north to south, known for its extensive coal former hunting grounds of the Oglala Lakota, the area is very sparsely populated and is known for its rolling grasslands and semiarid climate.

Coal. Wyoming, the nation's leading coal producer since 1986, provides about 40% of America's coal through the top 10 producing mines located in the Powder River Basin. Most Wyoming coal is subbituminous, which makes it an attractive choice for power plants because it has less sulfur and burns at around 8,400 to 8,800 BTUs per pound.

Some of these maps arn't very good or detailed. One map shows this basin covering both Wyoming and Montana. The reason I ask is OGE sends a UP coal train from the Powder River Basin to Red Rock, Oklahoma, near Ponca City. They have trackage rights over BNSF to get there which is why I see them. I'm looking at an a 1988 UP system map.
