Interesting map. But I think much of that area is the great basin, and deserts with extreme weather. I've flown over that region many times and much of it has the same features as the surface of Mars. I would imagine, most of it isn't worth much. </p>
Don't count on it. There was a lot of California that wasn't worth much until water was brought to it.
Wormholes, my boy, that's where the future is !
