Four Corners Monument
Four Corners Monument marks the quadripoint in the Southwestern United States where the states of Arizona, Colorado, New Mexico, and Utah meet. It is the only point in the United States shared by four states, and it also marks the boundary between two semi-autonomous Native American governments: the Navajo Nation and the Ute Mountain Ute Tribe. Visitors to the monument can position themselves at its center and “stand in four states at once.”
