Four Corners
Six governments have jurisdictional boundaries at the Four Corners Monument: the states of Arizona, Colorado, New Mexico, and Utah, as well as the tribal governments of the Navajo Nation and Ute Mountain Ute Tribe. The Four Corners Monument itself is administered by the Navajo Nation Department of Parks and Recreation. Other tribal nations within the Four Corners region include the Hopi and other Ute. The Four Corners is home to the capital of the Navajo tribal government at Window Rock, Arizona. The Ute Mountain Ute Tribal headquarters are located at Towaoc, Colorado.
Four continents
With the confirmed discovery that Australia was an island continent, the theme of the "Four Continents" lost much of its drive, long before a sixth continent, Antarctica, was discovered. The iconography survived as the Four Corners of the World, however, generally in self-consciously classicizing contexts: for instance, in New York, in front of the Beaux-Arts Alexander Hamilton U.S. Custom House (1907), four sculptural groups by Daniel Chester French symbolize the "Four Corners of the World."
