Natural Bridges National Monument is located about 50 miles northwest of the Four Corners boundary of southeast Utah at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name. The three bridges in the park are named Kachina, Owachomo, and Sipapu, which are all Hopi names. A natural bridge is formed through erosion by water flowing in the stream bed of the canyon. Eventually, as erosion and gravity enlarge the bridge’s opening, the bridge collapses under its own weight. There is evidence of at least two collapsed natural bridges within the Monument.
Horse Collar Ruin can be seen at the monument.
