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.

The history of nuclear weapons in Wyoming is intimately connected to the F. E. Warren Air Force Base, which in turn is tied to the global development of rocketry and nuclear might. If Wyoming were a nation, Warren AFB in Cheyenne would make it one of the world’s major nuclear powers. Its history with nuclear weapons in Wyoming is tied closely to the worldwide tensions of the Cold War, and with the development of missile-based nuclear weapons systems.

Fremont County, created in 1884 and named for famed explorer John C. Frémont, is still as diverse both economic factors and population as it was in the early days. Members of the Shoshone and Arapaho tribes continue to live and work on the Wind River Indian Reservation. Former reservation land north of Wind River was first opened to homesteaders in 1906. Ranching and irrigated farming have provided steadying influences over the decades to a local economy tied closely to booms and busts in gold, coal, uranium, iron-ore, oil and gas production.

Home to 19 of Wyoming’s first families, the Historic Governor’s Mansion was occupied from 1904 through 1976, opened to the public in 1977 and extensively renovated in 2004.

President Arthur appointed William Hale Governor of Wyoming Territory July 18, 1882. Governor Hale took the oath of office August 3, 1882 and served until his death at Cheyenne, Wyoming, January 13, 1885.

William Henry Jackson’s artistic passions began during childhood in upstate New York. By age 15, he was retouching photographs for professionals. His photos of the West, especially Yellowstone Park, many of them made in the 1870s with the Hayden survey, had an enormous influence on public perceptions of the American West.

Old West adventurer, orator, barber, reported bigamist, and passionate defender of civil rights, Kentucky-born William Jefferson Hardin was Wyoming’s first African-American legislator in its territorial days.

The Tongue River in northern Wyoming must have been as beautiful as it is now when George Bent saw it in 1865, with big, lazy curves under cottonwoods, the grass thickening on its banks and the trees sending out their first green shoots in early May. Nowadays, irrigated hay fields and the tiny towns of Dayton and Ranchester lie along the river. In May of 1865, however, one stretch of it was packed with human beings. That month, there was as large a town on the Tongue as that river has ever seen.

The Greybull Hotel, built in 1916, was the first and largest of its kind in downtown Greybull, Wyo., to be constructed with brick and concrete. Its main commercial space has served as a bank, a clothing store and a bar; during Prohibition there was a speakeasy in the basement. The hotel’s location--at the corner of Greybull Avenue and Sixth Street and at the intersection of Wyoming Highway 14 and Wyoming Highway 16/20—was of primary importance in the early days and remains so today.

In 1869, Fort Fred Steele was built by the U.S. Army to protect workers on the advancing transcontinental railroad at the spot where the rails crossed the North Platte River. The fort was closed in 1886, and the site, containing foundations of the original buildings, was much later acquired by the state.
