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.
