Mary Hughes was just 17 years old in 1908 when the No. 1 Mine exploded twice in one day—and for the second time in five years—in Hanna, Wyo. Her story shows the devastating impact that coal mine accidents had on families like the Hugheses across Wyoming’s mining communities, and reveals her determination to survive disaster.
In 1843, explorer John C. Frémont reported coal in what’s now southwest Wyoming. In the 1860s, the route of the new transcontinental railroad across Wyoming was chosen partly to access abundant coal deposits for fuel for the locomotives. Coal mining boomed, labor strife increased and Wyoming’s coal industry thrived despite worker strikes and a number of horrific mine accidents. Today, the state produces 40 percent of the nation’s coal, most of it from huge strip mines in the Powder River Basin in northeast Wyoming, for rail shipment to electric power plants in 34 states.
