Padres Butte towers over Lake Powell’s Padre Bay, both named for the Dominguez-Escalante Expedition, which crossed the Colorado River near this site in 1776. Padres and the other buttes in this area are composed of Entrada Sandstone, one of several geologic formations that form the sandstone “slickrock” that typifies much of southern Utah’s landscape.

At the mouth of Cottonwood Canyon, Fremont petroglyphs in the Northern San Rafael Style depict a hunting scene. The figures are etched into sandstone of the Green River Formation, and derive their contrast from the dark, weathered patina developed on the light-colored rock.

With the Deep Creek Mountains on the horizon, lush vegetation thrives in spring-fed wetlands that create an oasis in the middle of arid Snake Valley. Hundreds of springs and seeps in the valley provide habitat for many unique species of plants and animals.

Bryce Canyon National Park is actually a plateau-edge escarpment carved into the Claron Formation, estimated to be eroding back at the phenomenal rate of as much as 4 feet per century. The orange colors are due to varying amounts of iron oxide minerals that stain calcareous (limey) ancient soil, lake, marsh, and floodplain deposits of the Claron Formation.
