The Trail of the Ancients is a National Scenic Byway located in the states of Colorado and Utah. The route highlights the archaeological and cultural history of southwestern Native American peoples, and traverses the widely diverse geological landscape of the Four Corners region. It was the first National Scenic Byway that was designated solely for its archaeological sites. The entire route is approximately 480 miles (772.5 km) long.
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.
Four Corners Monument recognizes the only quadripoint in the United States. Members of the Navajo Nation (Utah, Arizona, and New Mexico), and the Ute Mountain Indian Reservation (Colorado) live in the Four Corners region on land surrounding the monument.
