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 | 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 | In 1869, explorer John Wesley Powell named the red-walled canyon on the Green River in Wyoming Territory “Flaming Gorge.” The Flaming Gorge Dam, completed in 1964, helps regulate water flows and its power plant generates electricity. The dam is located in Utah, but the reservoir stretches north into Wyoming near the town of Green River. In 1968, the U.S. Congress created the Flaming Gorge National Recreation Area, which is located in the states of Utah and Wyoming and draws visitors from around the world.
Encyclopedia | The story of uranium in Wyoming is a high-stakes drama whose cast includes fever-driven prospectors, ranchers defending their property rights, government officials intent on national security, entrepreneurs, engineers and world-class mining companies.
Encyclopedia | Sweetwater County’s history is as rich and diverse as its mineral wealth and population. The area became a transportation pathway, with the early pioneer trails and the transcontinental railroad and today’s Interstate 80 serving as important trade and travel routes. Mining of coal and trona and the production of oil and natural gas have been and continue to be significant industries, contributing to the county’s economic wealth and to Sweetwater County’s position as one of the top three revenue producing counties in Wyoming.
Encyclopedia | Accidents and disasters have plagued Wyoming coal mines since territorial times. In 1886, legislators created the office of the state mine inspector to help improve safety. Still, explosions and cave-ins killed hundreds of miners in the following decades. The worst accidents happened in Hanna in 1903 and near Kemmerer in 1923. Lawmakers continued to increase safety measures and eventually expanded the duties of the state mine inspector. Modern strip mining is far safer.
Encyclopedia | Seminoe and Kortes dams, both located in a remote stretch of northern Carbon County, Wyo., were constructed in the 1930s and 1940s primarily for the production of hydropower. While power plants at both dams still generate electricity, the area is frequented by tourists, especially fishermen who travel to the renowned Miracle Mile, just downstream from Kortes Dam, to catch trout.
Encyclopedia | Alcova Dam, a Bureau of Reclamation project, was completed in 1937. The reservoir opened in 1938 and a power plant was completed in 1955. The $20 million dam project didn’t achieve the high expectations of immense wealth that were forecast at the time of its inception, but continues to provide irrigation water for farmers and ranchers and generates hydropower for the area. Alcova Reservoir offers fishing, boating, camping and swimming opportunities for visitors.
