National Park Service Rangers have confirmed the collapse of a frequently visited arch in Rock Creek Bay in Glen Canyon National Recreation Area, Utah, which occurred on August 8, 2024.

The โDouble Archโ geologic feature has also been referred to as the โToilet Bowlโ, โCrescent Poolโ, and โHole in the Roofโ. No injuries were reported resulting from the collapse, which occurred on August 8, 2024.
Double Arch was formed from 190-million-year-old Navajo sandstone originating in the late Triassic to early Jurassic periods. Since formation, this fine-grained sand feature has been subject to spalling and erosion from weather, wind, and rain. Changing water levels and erosion from wave action is suspected of contributing to the ultimate collapse of the arch.
Glen Canyon National Recreation Area Superintendent Michelle Kerns stated, โthis 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 man made interventions. While we donโt 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.โ
