union pacific coal

Coal production at the Union Pacific mines at Reliance, Wyo., north of Rock Springs peaked at 1.4 million tons per year in the early 1940s. The mines are closed now but a vast steel-and-concrete tipple remains. Visitors are welcome, with a caveat: Stay out of the interior.

Stability can be fleeting in a boom-and-bust economy, especially for racial minorities facing discrimination. African-Americans struggled to earn respect in early 20th century Wyoming, and building churches in Rock Springs and other towns helped them anchor their lives with a sense of belonging.

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.

Hanna, Wyo., best known for its coal mines, was founded in 1889 by the Union Pacific Coal Co. as a company town. It has survived mining disasters and a long cycle of booms and busts. The last mines around Hanna closed in the mid-2000s. The town survives today as a bedroom community, with hopes of future mineral development.
