Four Corners Monument
The 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, leading to the area being named the Four Corners region. The monument also marks the boundary between two semi-autonomous Native American governments, the Navajo Nation, which maintains the monument as a tourist attraction, and the Ute Mountain Ute Tribe Reservation.
Four corners (Canada)
The four corners area is located between Kasba Lake to the north and Hasbala Lake to the south. It is located by an area of marginal taiga forest, which happens to be the only place in Nunavut which is not Arctic tundra or ice cap. It is hundreds of kilometres from any road or railway, but can be accessed from nearby Kasba Lake Airport/Water Aerodrome as well as from Points North Landing near Wollaston Lake.
