Popular 'Double Arch' Collapses In Glen Canyon National Recreation Area

The National Park Service said that the famed Double Arch at the Glen Canyon National Recreation Area collapsed into Lake Powell on Thursday (August 8).

The Double Arch, also known as the “Toilet Bowl," “Crescent Pool," and “Hole in the Roof," was a popular attraction among boaters and swimmers. Many people would jump off the arch and into the water below.

The geological feature was formed from 190-million-year-old Navajo sandstone and dates back to the time of the dinosaurs.

Park officials said the collapse was likely caused by "changing water levels and erosion from wave action."

“This event serves as a reminder of our responsibility and need to protect the mineral resources surrounding Lake Powell. These features have a life span that can be influenced or damaged by manmade interventions. 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," Glen Canyon National Recreation Area Superintendent Michelle Kerns said .
