Headward erosion into the Markagunt Plateau has created the spectacular badlands of the Cedar Breaks amphitheater. The brightly colored rocks of the Claron Formation include limestone, mudstones, sandstone, and conglomerate deposited in streams and lakes around 50 million years ago, as well as ancient soils developed in these deposits.

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.
