The Cheyenne Mountain Complex is located at Cheyenne Mountain Air Force Station. At the height of the Cold War in the late 1950s, the idea of a hardened command and control center was conceptualized as a defense against long-range Soviet bombers. The Cheyenne Mountain facility became fully operational as the NORAD Combat Operations Center on Feb. 6, 1967.
The Cheyenne Mountain underground military bunker is a warren of tunnels buried under 2,000 feet (610m) of granite, and sealed behind blast doors designed to withstand a 30 megaton nuclear explosion. The entrance has been featured in the movies Wargames and Independence Day, and the television show Stargate SG-1, in which the secretive Stargate commandoes were actually said to be based out of the bunker through the entirety of its long run.
Today, the Cheyenne Mountain Complex serves as NORAD and USNORTHCOM’s Alternate Command Center and as a training site for crew qualification.
NORAD Cheyenne Mountain Tunnel Run
The iconic portal at Cheyenne Mountain Air Force Station guards many things, which naturally means people are itching to see what’s inside. While most can’t enter the underground complex, those interested in checking out the mile-long tunnel and blast doors can do so during the Cheyenne Mountain Tunnel Run. DoD ID cardholders have the opportunity to participate in tunnel run at Cheyenne Mountain Air Force Station, Colorado. Part of the run includes a route through the Cheyenne Mountain Complex, giving the runners an inside look at the mountain-based facility. No one can say for sure if there are aliens or zombies in the tunnel, but there is definitely something lurking in the shadows.
