The unpaved section of the Burr Trail in Utah, approaching Capitol Reef National Park. Formations of the Upper Muley Twist Canyon, composed of Navajo and Wingate sandstone layers are visible in the foreground, in the background Henry Mountains, composed mainly of diorite. Interesting fact- Henry Mountains are home to one of the only three free-roaming and genetically pure herds of bison in the United States (the other two are in Yellowstone National Park and Wind Cave National Park).
