The Four Corners is a geographic region located in the Southwestern United States. It is defined by the convergence of the southwestern corner of Colorado, the southeastern corner of Utah, the northeastern corner of Arizona, and the northwestern corner of New Mexico.
The area is characterized by its rural, rugged, and arid landscape as part of the larger Colorado Plateau. A significant portion of the region belongs to semi-autonomous Native American nations, including the Navajo Nation, which is the largest, followed by the Hopi, Ute, and Zuni tribal reserves and nations.
New Mexico is the largest state within this specific region and ranks as the fifth-largest state in the United States.
