| Navajo National Monument is located within the Navajo Nation in northwestern Arizona. The national monument was proclaimed in 1909 by President Theodore Roosevelt but encompasses only about 360 acres. The park features spectacular scenery of parts of Skeleton Mesa (and greater Shonto Plateau within the even greater Colorado Plateau). Triassic- and Jurassic-age rock formations are exposed in Long Canyon and side canyons that cut through the upland region. The park also features protected archeological sites and partially "restored" ruins of Ancestral Puebloan people that inhabited the region between 700 and 1500 years ago. |
