Grants's history as the Uranium Capital of the World
The Grants area's identity as the Uranium Capital of the World is genuinely earned — during the peak of the Cold War-era uranium boom (roughly 1950 through 1980), the Grants Mineral Belt produced approximately 50% of all uranium mined in the United States and was one of the largest single uranium-producing regions in the world. The boom began in 1950 when Navajo rancher Paddy Martinez discovered yellow uranium ore on Haystack Butte northwest of Grants, immediately attracting prospectors, mining companies, and federal Atomic Energy Commission contracts that would transform the regional economy across the following three decades.
The economic impact on Grants and surrounding Cibola County was substantial. The town's population grew from approximately 2,000 in 1950 to over 12,000 at the peak of the boom in the late 1970s, with mining and milling companies including Anaconda, Kerr-McGee, United Nuclear, Homestake Mining, and several others operating substantial underground mines, open-pit operations, and processing mills across the surrounding country. Mining jobs paid wages substantially above the prevailing rates for the rural Southwest, and the boom-era population included families relocating to Grants from across New Mexico, the broader Southwest, and Native American communities including substantial Navajo and Acoma populations working in the mines.
The boom ended in the early 1980s as Cold War uranium demand declined, the Three Mile Island accident reduced civilian nuclear power expansion in the United States, and lower-cost uranium production from Australia, Canada, and Africa undercut domestic American uranium prices. Most of the Grants-area mines closed between 1980 and 1990, and the regional population declined substantially. The museum exists in part to preserve and interpret the boom-era history that defined three decades of Grants identity and continues to shape the contemporary regional economy and demographic patterns.
