Grand Junction Climax Uranium Mill Site, Colorado

This was the site of a former uranium mill, which was removed and cleaned up beginning in the mid-1980s, as part of the federal Uranium Mill Tailings Remedial Act Project. Also known as the Climax Mill site, it covers approximately 114 acres. The mill operated for 19 years, and shut down in 1970. Tailings left at the site have been used as aggregate or fill at more than 4,000 construction projects throughout the region.
