The Grand Canyon in Arizona is a natural formation distinguished by layered bands of red rock, revealing millions of years of geological history in cross-section. Vast in scale, the canyon averages 10 miles across and a mile deep along its 277-mile length. Much of the area is a national park, with Colorado River white-water rapids and sweeping vistas.
