Kachina Bridge is a natural sandstone arch in Natural Bridges National Monument near Blanding, Utah, and one of the monument’s three notable stone spans. With a 210-foot span and 44-foot width, it has the widest girth in the park and ranks among the longer natural arches in the United States. The surrounding area was used by early Ancestral Pueblo peoples, present here as early as 7500 BCE. Government surveyor William Douglas named the arch after petroglyphs and pictographs at its base that he believed depicted Kachina dancers. In July 1992, about 4,000 tons of sandstone fell from inside the arch, enlarging its opening through ongoing erosion.
