The legendary ‘Toilet Bowl’ has fallen.
A cherished natural rock feature that stood as a majestic sentinel for millions of years has dramatically crumbled into Lake Powell, within Utah’s Glen Canyon National Recreation Area. Known widely as the Double Arch, this awe-inspiring geological marvel—once a magnet for visitors—collapsed on Thursday, August 8th.
Also referred to as the Toilet Bowl, Crescent Pool, and the Hole in the Roof, the Double Arch was crafted from 190-million-year-old Navajo sandstone. Its grandeur lay in its resemblance to a colossal skylight set within a natural grotto, allowing sunlight to dance upon a shimmering expanse of water in Rock Creek Bay. According to the National Park Service (NPS), the ancient formation had been subject to relentless forces of nature since its inception, leading to its gradual erosion and eventual disintegration.

The dynamic interplay between the arch and its environment may have been exacerbated by the fluctuating shoreline of Lake Powell. The NPS attributes this instability to the lake’s declining levels since 2001, driven by climate change and an extended drought. “Shifting water levels and the erosive force of wave action are believed to have played a critical role in the arch’s collapse,” stated the NPS.
“This event underscores our obligation to safeguard the natural resources around Lake Powell,” remarked Michelle Kerns, Superintendent of Glen Canyon National Recreation Area. “These features have finite lifespans and are vulnerable to human impact. Although the precise cause of the collapse remains uncertain, we are committed to preserving and protecting these wonders for the enjoyment of future generations,” she affirmed.
Spanning from Lees Ferry in Arizona to the Orange Cliffs of southern Utah, Glen Canyon National Park encompasses approximately 5,060 square kilometers (1.25 million acres) and is home to several iconic natural landmarks. These include the globally renowned Horseshoe Bend on the Colorado River and the Rainbow Bridge, one of the world’s largest natural bridges.
Fortunately, the NPS has confirmed that the collapse did not result in any injuries. With millions of tourists flocking to the national park annually, Kerns emphasizes the critical importance of respecting these fragile natural treasures.
“While we invite you to experience our remarkable resources, please remember to leave no trace,” she urges.
