Apollo Temple is a 6,252-foot summit in the Grand Canyon of northern Arizona, rising from the canyon interior near Cape Royal on the North Rim and towering more than 3,600 feet above the Colorado River in less than two miles. Named in 1902 by geologist François E. Matthes for the sun god Apollo, in keeping with Clarence Dutton’s deity-based naming of canyon landmarks, the name was officially adopted in 1906 by the U.S. Board on Geographic Names. Its layered summit exposes Supai Group strata above Redwall Limestone and the Cambrian Tonto Group, making it both a dramatic landform and a visible record of Grand Canyon geology.
