A large geological feature in southern Utah known as the “Double Arch,” the “Hole in the Roof” and sometimes the “Toilet Bowl” has collapsed. National Park Service officials said Friday that no injuries were reported. The popular arch in the Glen Canyon National Recreation Area fell Thursday. Park rangers suspect changing water levels and erosion from waves in Lake Powell contributed to its demise. The arch was formed from 190 million-year-old Navajo sandstone originating in the late Triassic to early Jurassic periods. The fine-grained sandstone has endured erosion from weather, wind and rain.
