Cheyenne Mountain's entrance tunnel

In the science fiction television show Stargate SG-1, Stargate Command (also known as the SGC), is located in the Cheyenne Mountain complex in Colorado. It houses the Stargate through which SG teams are sent to other worlds. In the film Stargate before the formal establishment of the SGC a fictional facility under Creek Mountain, Colorado was used as a base of Stargate operations instead.

Built into the mountain to protect itself from nuclear attack, the complex is also protected from the Goa'uld - although in alternate universes revealed in several episodes of the show, it was unable to withstand a large-scale space-based assault by them. Instead, the SGC relies primarily upon the "Iris" to prevent hostile travellers from entering via the Stargate itself.

The SGC has a self-detruct mechanism that was activated more than once to prevent the spread of an alien vius/intruder.
