The
Four Corners is a region of the United States consisting of the southwestern corner of
Colorado, southeastern corner of
Utah, northeastern corner of
Arizona, and northwestern corner of
New Mexico. The Four Corners area is named after the
quadripoint where the boundaries of the four states meet, where the
Four Corners Monument is located. It is the only location in the United States where four states meet. Most of the Four Corners region belongs to semi-autonomous Native American nations, the largest of which is the
Navajo Nation, followed by
Hopi,
Ute, and
Zuni tribal reserves and nations. The Four Corners region is part of a larger region known as the
Colorado Plateau and is mostly rural, rugged, and arid. In addition to the monument, commonly visited areas within Four Corners include
Monument Valley,
Mesa Verde National Park,
Chaco Canyon, and
Canyon de Chelly National Monument. The most populous city in the Four Corners region is
Farmington, New Mexico, followed by
Durango, Colorado.
