The gate room was fairly dark when I took these pictures, so I had to use a flash. They are displayed in order, moving in through one of the side doors and going around towards the back of the Stargate. (Click on the thumbnail graphics for the full-sized images.)
These are just other views of the Stargate, under normal room lighting. I was fortunate enough to be able to get a shot of the Stargate with the wormhole open.
Many thanks to my friend "Jim", who was able to sneak me into the Cheyenne Mountain complex and back out again, so I could get these pictures...
