Being born and raised in Colorado for 35 years, I've heard about NORAD and Cheyenne Mountain all throughout my life. However, I've never been there for, well, I would say obvious reasons, but I've always been intrigued by the fact that a government facility is literally inside of a mountain.

Apparently, NORAD has moved locations, but Colorado Springs' Cheyenne Mountain is still occupied by a government facility that employs a sizeable staff roughly 2000 feet underground.

The facility is equipped to withstand serious foreign attacks if need be, as well as natural disasters such as earthquakes.
