Shafer Trail is the name given unofficially to a rough dirt road near Moab and Potash. I am
unaware of an official description of "Shafer Trail," so I am treating it as the dirt road
that runs from the Potash boat ramp to Canyonlands National Park, passing the potash
evaporation ponds on the way. The official name for this dirt road is San Juan County
Route 142, as described in a gallery about the official names of roads in this area.

A few miles beyond the Potash boat ramp, the road passes the huge blue evaporation ponds
of Intrepid Potash and continues to a fantastic view of the river opposite the Goose Neck,
a formation inside a bend in the river. Then it ascends to Canyonlands National Park,
intersecting the White Rim Trail (another rough dirt road). Signs recommend traveling
here with high-clearance four-wheel-drive vehicles: you can expect to encounter bumps,
ruts, drop-offs, and dust on this road whose condition varies from year to year.
