The Subway - Palo Duro Canyon

Palo Duro Canyon

This rock formation - unknown to most visitors to Palo Duro Canyon, and even to many of the park rangers - is called "the Subway" by some of the locals who have visited this location many times. Located just above the Central Utah Slot Canyons in a remote region of the park, this beautiful rock structure has been cut by erosion from wind and rain. Photo © copyright by Rob Greebon.
