Canyon de Chelly
Pictured is Arizona's , a nearly 84,000-acre national monument in the northeastern part of the state. It is entirely on the Najavo Reservation, though it is administered by the National Park Service. The canyons--the park is actually comprised of five: Canyon del Muerto, Black Rock Canyon, Canyon de Chelly, Monument Canyon and Bat Canyon--were formed by erosion of sandstone and igneous rock caused by the local rivers and streams.
