Cheyenne Mountain - Located near the city of Colorado Springs, Colorado, Cheyenne Mountain  (Cheyenne Mountain Operations Center) is a high-security government facility featured on the science fiction adventure STARGATE SG-1/SHO/SCI/1997+. The facility houses a top-secret operation called the Stargate Command (SGC). Run by the U.S. Air Force, it contains an ancient portal device (The Stargate) created millions of years ago by a race called the Ancients. The Stargate enables near-instantaneous travel via worm-hole technology from one point in the galaxy to another. The Stargate's embarkation room is located on Level 28. The Stargate is used to develop diplomatic relations with other species on other planets like the Asgard, and as a frontline weapon against a sinister invading forces of the Goa'Uld. The base operated under the command of Major General George S. Hammond for several years, and later by diplomat Elizabeth Weir and finally, by the newly promoted Brigadier General Jack O'Neill. Situated above the Stargate operation is an other sensitive military operations called N.O.R.A.D. "North American Aerospace Defense Command."  TRIVIA NOTE: N.O.R.A.D. is actually a real military organization located beneath Cheyenne Mountain. See also - Goa'Uld
