Northeast Arizona is a region of the U.S. state of Arizona commonly including Apache County and Navajo County. Some notable towns there are St. Johns, Eagar, Holbrook, Show Low, Winslow, Window Rock, Fort Defiance, Ganado, Chinle, and Kayenta.
It is the location of several Indian reservations including all of the Zuni Indian Reservation and most parts of the Hopi Reservation, the Navajo Nation, and the Fort Apache Indian Reservation. The rugged desert landscape of Northeast Arizona has been inhabited by indigenous peoples since at least the construction of what are now the ruins at Monument Valley, Navajo National Monument, and Canyon de Chelly National Monument.
Northeast Arizona is arid, largely free of greenery, and characterized by hills, mesas, buttes, cliffs, and canyons. The windy stony plains of the Petrified Forest National Park exhibits parts of the barren colorful Painted Desert as well as preserved Native American petroglyphs. Northeast Arizona is also home to the Apache-Sitgreaves National Forest and Four Corners Monument.
