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.
Trail of the Ancients
The National Scenic Byway crosses the Colorado Plateau of the Four Corners region along prehistoric sites of Native Americans, including the Navajo, Utes and early puebloan people, who lived and farmed in the area from about 1 CE to about 1300 CE. There were people hunting and gathering for food in the Four Corners region by 10,000 B.C. or earlier. Geological features include sandstone-rimmed canyons, snow-capped mountains, red rock landscapes and green valleys. Most of the stops — archaeological sites, Native American lands or modern communities — are near or on paved roads, but some of the roads are rugged graded roads.
