As per the Colorado Department of Public Health and Environment, there are five former Atlas E intercontinental ballistic missile sites around the state, four of which are in Weld County and can still be seen at the Missile Silo Park.

Located between Greeley, Windsor, and Loveland, the Missile Silo Park gives visitors an inside glimpse at these once state-of-the-art, now dark and eerie Cold War-era structures, plus jaw-dropping views of the surrounding landscape.

In addition to Colorado's Atlas E. Missile Site, Insider also notes Bodie, California, the Nuclear Aircraft Laboratory in Dawson Forest, Georgia, and Tanner's Hospital in Ely, Minnesota.
