'Canyon de Chelly National Monument', established
April 1,
1931 as a unit of the
National Park Service, is located in northeastern
Arizona, within the boundaries of the
Navajo Nation. The monument covers 131 square miles and encompasses the floors and rims of the three major canyons: de Chelly, del Muerto, and Monument. These canyons were cut by streams with headwaters in the
Chuska mountains just to the east of the monument.
Its 83,840 acres (339 km²), all
nonfederal, preserve artifacts of the early indigenous tribes that lived in the area, including the
Ancient Pueblo Peoples (also called Anasazi) and
Navajo.
Canyon de Chelly is unique among National Park service units, as it consists entirely of Navajo Tribal Trust Land that remains home to the canyon community. Access to the canyon floor is restricted, and visitors are allowed to travel in the canyons only when accompanied by a park ranger or an authorized Navajo guide. The only exception to this rule is the 'White House Ruin' Trail. Most park visitors arrive by automobile and view Canyon de Chelly from the rim, following both North Rim Drive and South Rim Drive. Ancient ruins and geologic structures are visible, but in the distance, from turnoffs on each of these routes.
The National Monument was listed on the
National Register of Historic Places on
August 25,
1970.

Name
The name ''Chelly'' (or ''Chelley'') is a Spanish
borrowing of the Navajo word ''Tséyiʼ'', which meaning "canyon" (literally "inside the rock" < ''tsé'' "rock" + ''-yiʼ'' "inside of, within"). The Navajo pronunciation is . The Spanish pronunciation of ''de Chelly'' was adapted into English apparently through modelling after a French-like
spelling pronunciation, and the name is now
pronounced ([də'shā]).
