Oh my gosh. That map of the SBP area is SOOOOO cool! That's going to be *very* helpful when writing future QL stories. Did it take long to find a map like that?
I knew the real name for it was Stallion Gate Range and after some research discovered that Stallion Gate is houses at the White Sands Missile Testing range. Trinity site is there where they detonated the first atomic bomb, so I was able to add in the Starbright Project nearby (where Quantum Leap will one day be) to keep with the cannon of the show.
Here is another map. This one is just of the national monument inside the white sands test center, which is south of Trinity site on the map I have on the website.
