Arches National Park
The third largest arch in the park, Double Arch's larger span is 144 feet wide by 112 feet high (44 by 34 meters). The smaller opening is 67 feet wide by 86 feet high (20 by 26 meters).
For a closer look at Double Arch, walk this easy trail and stand underneath the towering arch. From there, look up and see the rim of what was once a pothole, now open to the sky.
At Double Arch, three major openings are enlarging side by side. They all began as one pothole.
Pothole Arch Formation
Pothole arches start as depressions near a cliff face.
Pools of water collect and slowly deepen the pothole. Over time, water seeps through to the cliff face, forming an alcove.
Eventually, the enlarging pothole meets the roof of the expanding alcove, creating an opening. The arch matures as erosion continues.
