Union Pacific's Potash Turn (I think that's the correct name) heads up Bootlegger Canyon on its way to Grand Junction with hoppers picked up at the mine at Potash. In a moment it will enter Bootlegger Tunnel and later emerge on a shelf above US 191, opposite Arches National Park (about three miles north of Moab).

Two of its four units are locomotives dedicated to UMTRA "dirt train" use. They were picked up at Brendel during the run from Grand Junction to Potash. They are being taken to Grand Junction to be refueled.

I was fortunate to see the train three times his day: when it came downgrade here (another photo), while switching at Potash, and here.
