Located in a high desert plain in the Southwest U.S., the Four Corners region – Arizona (AZ), Colorado (CO), New Mexico (NM), and Utah (UT) - is the only place in the country where four states touch. Three of the four corners are on the Navajo Reservation and the fourth, in Colorado, is on the Ute Mountain Reservation.
