Double Arch (Arches National Park)

Double Arch is a close-set pair of natural arches, one of the more known features of Arches National Park in Utah, United States. From the Double Arch parking area it's a 0.5 mile (0.8 km) round trip to the arches. There are no guardrails or fences to prevent visitors from exploring directly beneath and through the arches.

The area was used as a backdrop for the opening scene of Indiana Jones and the Last Crusade, in which the arches are briefly visible. However, the cave shown in the movie does not exist.

Double Arch was formed differently than most of the arches in Arches National Park. It is what is known as a pothole arch; it formed by water erosion from above rather than more typical erosion from the side. The larger opening has a span of 148 feet (45,1 meters) and a height of 104 feet (31,7 meters), both measured using precision laser equipment on June 23, 2009.
