boom and bust

Rock Springs was bursting in 1977 when “60 Minutes” came to town to cover sleaze and alleged corruption. Soon after, top cop Ed Cantrell shot his undercover agent, Mike Rosa, in a police cruiser in front of the Silver Dollar Bar. The crime, the trial and its drama fixed boomtime Wyoming in the national imagination as a new kind of wild West.

Wyoming’s coal mining industry was secure until the early 1950s, when the Union Pacific switched to diesel-powered locomotives. Laid-off miners and their families struggled; little company towns disappeared. Eventually, trona mining expanded and replaced many of the coal jobs—and in the 1970s, coal came roaring back.

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.

The Powder River Basin coal-bed methane boom in the early 2000s stirred controversies over land rights, mineral rights, environmental stewardship, the disposal of water and—at every turn—politics. Now, few of the 29,000 wells drilled produce much gas and around 3,000 wells are abandoned and left to the state to clean up. 

Prospectors first struck oil in the Salt Creek Oil Field in northern Natrona County, Wyo. late in the 1880s. The first gusher came in in 1908. The subsequent boom lasted until the late 1920s, peaking in 1923, when the field produced more than 35 million barrels of oil. Tom Wall, who went to work in the field in 1917, stayed for decades and in the 1970s wrote out his memories of life in the oil patch through boom and bust. After 125 years and thanks to new technologies, the Salt Creek Field continues to produce today.
