Annie was asked about the northern border of the desert, and she said it was roughly along I-80, which includes Rock Springs, Rawlins, and Green River. The county also includes a saddle of the Rocky Mountains between the Teton Range to the north and the Medicine Bows to the south and east. Gale-force winds that fell semis (see my posts in Anything Goes), and thousands of Antelope move through this area every year. Last fall, Pete and I traversed the Muddy Gap over the Rockies and visited Independence Rock where pioneers left their messages.
Thanks! I'm gonna study this on my Wyoming map!
I never really checked before, but it sounds like I-80 pretty much follows the route of the Union Pacific Railroad.
