Update Maps for Prime Base Location

[nuke11]

Since the original topographical maps provided in the module are not the best reproductions, they should be updated to a more "modern" version available from the USGS, which I'm guessing Terry and TML would be working on at some point.

Topographical maps can be added to Google Earth easily (not sure the legalities of using maps from Google Earth in products) and we have some excellent online resources available today, that where not available when it was originally produced.

For example;

I have lost contact with Nick and Bill, but it could have been an interesting discussion on how they came to choose this location of Nevada. Unless one of them traveled thru the area at some point, or thru darts at a map, how did they pick this area?
