Wyoming's fossils have been important to science since the 1870s and continue to be useful today. Remains of Triceratops, Diplodocus, Tyrannosaurus and others have helped answer—and raise—many questions about the ancient history of the planet and have captured popular imagination with their size or fierce appearance. The scientific value of these fossils and the public interest in them has brought collectors who excavate fossils and ship them to museums all over the country for further study and display. Only a few major finds from Wyoming have remained in the state.
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.
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.
Anchor Dam was built in the 1950s on upper Owl Creek in Wyoming’s Bighorn Basin. The bedrock under the reservoir site is porous, and the reservoir has never held much water. The U.S. Bureau of Reclamation more than doubled its initial costs with subsequent mitigation efforts, which proved unsuccessful. The dam stands today high above a small pool of water.
As its name suggests, Hot Springs County, Wyo., draws many visitors to the world-famous thermal mineral waters located in Thermopolis, the county seat. But the area also provides stunning scenic views for those who travel through the Wind River Canyon and gives fascinating glimpses into prehistoric times at the Legend Rock petroglyphs and the Wyoming Dinosaur Center.
Boysen Dam, named for local businessman Asmus Boysen, was constructed on the Wind River in the 1940s to control flooding and to provide irrigation water for agricultural purposes. The dam was completed in early 1953 and its power plant continues to generate electricity today. Boysen Reservoir provides recreational opportunities as well.
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.
Largely forgotten today is the stiff local resistance that arose in Jackson Hole, Wyoming, to the creation and later the expansion of a national park there. The story covers 31 years of controversy, and includes a Rockefeller, a movie actor and a group of armed ranchers trailing cattle illegally across a national monument, and some of the most beautiful scenery in North America.
In August 1856, more than 1,000 Mormon emigrants in the Willie and Martin handcart companies left Florence, Nebraska Territory, with plans of reaching Salt Lake City and the headquarters of The Church of Jesus Christ of Latter-day Saints before winter. Their late start, substandard equipment and lack of sufficient supplies had disastrous consequences when they were hit by winter storms. Hundreds died on the journey across what’s now Wyoming and into Utah. Images of emigrant families pulling handcarts have since become an LDS Church icon of the triumph of faith over adversity.
In 1992, officials from The Church of Jesus Christ of Latter-day Saints placed monuments commemorating the ill-fated, 1856 journey of the Willie and Martin handcart companies at Martin’s Cove, on public land leased for livestock grazing by the Sun Ranch near Devil’s Gate in central Wyoming. In 1997, the LDS church bought the ranch, and in subsequent years tried to get a bill through Congress to allow church purchase of the cove as well. The bill was opposed by some Wyoming citizens, however, and by Wyoming’s U.S. senator, Craig Thomas. Instead, a compromise 25-year lease was negotiated between the church and the Bureau of Land Management, guaranteeing public access to the public.
