If your interested....you could go thru the Kemmerer ( an old coal mining town)area. Your only, steep climb... would be Parley’s Canyon going east on I-80 out of Salt Lake! Kemmerer,Wy. Was where JC Penny, got his start. The “Mother Store” is there and still operating.His home, is still there and you can do a walk-thru. There is a pretty good museum , with lots of area history. Kemmerer was very active in the “bootlegging” business during “prohibition”. Just west of Kemmerer, on Hwy. 30, is the Fossil Butte National Monument....world renowned for it’s sea life and fish fossils. Lastly, just south of town, is an “open pit” coal mine....was once the largest in the nation. Not sure now.....but once offered tours. It is “one very big, very deep hole! The pit and some of the massive equipment....really is something to see!
If, you go thru Kemmerer, contine north, up and thru the Hoback Canyon....you’ll cross the Snake River, just south of Jackson, Wy.
