Encyclopedia | 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.
Encyclopedia | Billy Owen never saw a railroad until he was eight years old. His mother had told him about railroads. But in his mind as he traveled east by wagon train across Wyoming in the spring of 1868, he had imagined railroad wheels that looked something like wagon wheels. They rolled in grooves. Each groove was made by two rails. That meant it took four rails, as he imagined it, to make a track.
Encyclopedia | The Mineral Leasing Act of 1920 established the modern system by which oil and coal companies may lease federal land. This system has proven enormously beneficial to Wyoming’s state coffers since it was first enacted nearly 100 years ago. How this all came about is a story of early oil producers looking for a way around a presidential order and a highly contentious Supreme Court case, all with lucrative results for the state of Wyoming—and a stabilizing result for the industry.
Encyclopedia | A late-1960s Atomic Energy Commission plan to extract Wyoming natural gas with five underground nuclear explosions won strong initial support from the oil and gas industry and the federal government. Finally, however, the idea stalled, thanks to the emergence of more information on possible dangers, to Washington politics, and especially to intense local opposition in Sublette County, Wyo., where the devices were slated to be detonated.
Encyclopedia | Wyoming’s sheep business never had the fame or cachet of Wyoming’s cattle business, but at the turn of the last century sheep raising was more widespread and probably more lucrative. Cattlemen, however, reacted violently to sheepmen’s entry onto the public range, and for a time deadly raids by cattlemen on flocks, sheepdogs and sheepherders were chronic. A gradual decline in wool and lamb prices since the 1920s has left only about a twentieth as many sheep on Wyoming ranges now as there were in 1909.
Encyclopedia | 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.
Encyclopedia | Natural gas has been flowing from the Jonah Field and Pinedale Anticline in western Wyoming since the early 1990s, bringing with it substantial profits, tax revenues, prosperity, social change, air pollution, and declines in local mule-deer populations. The story goes to the heart of Wyoming’s oil and gas culture, and raises important questions about energy production’s long-term costs and benefits.
Encyclopedia | The construction of the Union Pacific in 1868 gave rise to the towns, geography of settlement and the economy of new Wyoming Territory in 1869. Obstacles to construction were both physical and financial, and the railroad overcame them with sometimes slapdash results—hastily laid track and rickety bridges, watered stock and Congressional corruption. But the Union Pacific contributed enormously to Wyoming’s growth and development, made its modern economy possible and continues today as an economic power in the state.
