The Cheyenne Mountain Complex is a hardened underground command bunker dug beneath a Colorado mountain, operational since 1966 and long associated with NORAD's missile- and air-warning mission. Popular folklore frames it as a hub for tracking unidentified 'unknowns', though it is fundamentally a documented military command center. Its tunnels and blast doors are real and well-known.
