Cliff dwelling at Canyon de Chelly National Monument in Arizona

The Canyon de Chelly National Monument, one of the most visited national monuments in the US, is located within the boundaries of the Navajo Nation. The park protects ancient ruins of indigenous tribes that once lived in the area and still serves as home to about 40 Navajo families. The 84,000-acre national monument is owned by the Navajo Nation but is managed in cooperation with the National Park Service.
