The National Park Service (NPS) has confirmed the collapse of a beloved geological feature known as the “Double Arch” in Rock Creek Bay, located within Utah’s Glen Canyon National Recreation Area. This natural wonder, which had long been a popular destination for visitors, was also commonly referred to as the “Toilet Bowl,” “Crescent Pool,” and “Hole in the Roof.” The collapse of this iconic formation has marked a significant change in the landscape of the area. Fortunately, no injuries were reported as a result of the incident.
Double Arch was a remarkable natural structure, formed from 190-million-year-old Navajo sandstone that dates back to the late Triassic to early Jurassic periods. Over millions of years, this fine-grained sandstone was shaped and sculpted by the relentless forces of nature, including weather, wind, and rain. These elements gradually wore away at the rock, causing spalling and erosion that contributed to the arch’s eventual collapse. The National Park Service suspects that fluctuating water levels and erosion from wave action in the bay may have played a significant role in the arch’s ultimate demise.
The collapse of Double Arch has not only altered the physical landscape of Rock Creek Bay but also serves as a poignant reminder of the fragility of natural structures. These formations, while seemingly eternal, are subject to the same forces of change that shape all geological features. The loss of this arch is a testament to the ongoing process of natural erosion and the impact of environmental conditions over time.
Michelle Kerns, Superintendent of the Glen Canyon National Recreation Area, emphasized the importance of conservation efforts in the wake of this event. “The collapse of Double Arch serves as a powerful reminder of our responsibility to protect the mineral resources surrounding Lake Powell,” Kerns stated. “These features, while enduring, have a finite lifespan that can be influenced or damaged by human activity. While we don’t yet know the exact cause of this collapse, it underscores the need for continued vigilance in our resource protection efforts. We are committed to ensuring that Lake Powell’s natural wonders are preserved so that future generations can experience their beauty. We encourage all visitors to enjoy these resources, but to do so with care and respect—leaving no trace behind.”
The Double Arch had been a symbol of the dynamic and ever-changing nature of Glen Canyon’s landscape. Its loss is a reminder of the impermanence of such features and the delicate balance that exists in natural environments. As the National Park Service continues its investigation into the factors that led to the collapse, they are also reaffirming their commitment to preserving the geological heritage of Glen Canyon.
The NPS has shared images of Rock Creek Bay, both before and after the collapse, highlighting the dramatic transformation of the area. These images serve not only as a historical record but also as a call to action for increased awareness and support for conservation efforts. The preservation of natural wonders like Double Arch is vital to ensuring that future generations can continue to marvel at the beauty and history of places like Glen Canyon.
The Glen Canyon National Recreation Area remains a place of extraordinary beauty and significance, and the NPS is dedicated to maintaining its integrity for years to come.
