This S-Curve (known as Thompson Curve) offers up just about everything you could ask for here in the Utah desert. In addition to the wonderful geography of the curve itself, you get a bit of desert vegetation (what little there is), dirt mounds, and the hard rock fast of the Book Cliffs in the distance. This UP passenger special is carrying UP's upper management (and their families) on a trip from Rifle, CO to Potash, UT at the south end of the Cane Creek Subdivision.
