PAGE, Ariz. – Double Arch, a frequently visited arch in Rock Creek Bay in Glen Canyon National Recreation Area, Utah, collapsed Thursday, National Park Service rangers have confirmed.
This popular geologic feature, also referred to as the “Toilet Bowl”, “Crescent Pool” and “Hole in the Roof” was formed from 190-million-year-old Navajo sandstone originating in the late Triassic to early Jurassic periods, according to a news release. Since its formation, Double Arch, a “fine-grained sand feature,” has been subject to spalling and erosion from weather, wind and rain.
“This event serves as a reminder of our responsibility and need to protect the mineral resources surrounding Lake Powell,” Glen Canyon National Recreation Area Superintendent Michelle Kerns said in a news release.
No injuries were reported from the collapse, which is being attributed to changing water levels and erosion from wave action.
“These features have a life span that can be influenced or damaged by manmade interventions,” Kerns said. “While we don’t know what caused this collapse, we will continue to maintain our resource protection efforts on Lake Powell for future generations to enjoy. Please enjoy our resources but leave no trace.”
