I wonder if the Cheyenne Mountain NORAD facility came to be before or after the tunnel system and Denver facility had been established, which is the cause and which is the effect. Oh no, now I'm wondering if Mogollon Moutain, a vast and naturally beautiful area, contains a major node. It's not all that far southwest of Denver and could be a transition point, a more literal four corners facility. (watershed border between east and west of the continent crosses the area)
