Sorry Everyone, but those are ATLAS F missile silos. I have bee inside of them. The one in Lake Arthur is actually the city well!. The bunkers at the Roswell Air base is used to store fireworks for Longhorn mfg. among other things.
The Cul de sac looking things 30 miles to the NE are nothing but oil wells. Surely guys its 2004 the age where we are peering into peoples backyards from our PCs
dont get me wrong, I love it. But if theres something to be hidden. It will be far beneath the crust. There are 12 aroung the roswell area within 30 miles.
Heres some interesting read on the atlas F
