Four Corners Monument

Four Corners Monument is a boundary marker at the state borders of Arizona, Colorado, New Mexico, and Utah in the United States. A flat granite platform holds an embedded bronze disk, and each of the four states is represented by its seal in the surrounding slabs.

Early surveyors marked the point in 1868 when the western territories received their final boundaries. The current platform was installed in 1992 and replaces earlier simpler markers that had weathered over the decades.

The site is managed by the Navajo Nation, and local artisans offer handmade silver jewelry, pottery, and woven textiles. Visitors can speak directly with vendors and learn about the patterns and symbols in their work.

The site sits away from main highways in a dry highland region, so visitors should bring plenty of water and sun protection. The access road is unpaved and can become difficult to navigate after rain, especially during summer thunderstorm season.

Many visitors attempt to stand in all four states at once by spreading their arms and legs across the respective quadrants. The bronze disk shows fine lines that trace the exact course of the borders and mark the intersection at the center.
