Sandstone Rocks in Vermillion Cliffs

Crossbeds of Navajo sandstone paint the Coyote Buttes in hues created by the precipitation of oxides. From a 3,000-foot-high escarpment to a canyon 2,500 feet deep, Vermilion Cliffs National Monument encloses a remote and unspoiled, 294,000-acre geologic treasure on the border of Arizona and Utah north of the Grand Canyon.
