A frequently visited arch in Rock Creek Bay, Glen Canyon National Recreation Area (NRA) in Utah, has collapsed, the National Park Service (NPS) reported on Friday. The geological feature, known as the “Double Arch” and also referred to as the “Toilet Bowl,” “Crescent Pool,” and “Hole in the Roof,” fell on Thursday.
Formation and Environmental Impact
The Double Arch, which was composed of Navajo sandstone estimated to be around 190 million years old, had been deteriorating over time. The sandstone, known for its fine grain, had been subjected to significant spalling and erosion due to wind and rain. The NPS indicated that recent changes in water levels and the impact of pounding waves may have contributed to the arch’s collapse.
No Injuries Reported
Fortunately, no injuries were reported from the incident. The collapse highlights the natural vulnerability of geological formations, particularly those exposed to the elements and human activity.
Call for Preservation
Michelle Kerns, superintendent of Glen Canyon National Recreation Area, emphasized the importance of protecting the mineral resources around Lake Powell. “This event serves as a reminder of our responsibility and need to protect the mineral resources surrounding Lake Powell,” Kerns stated. “These features have a lifespan that can be influenced or damaged by manmade interventions.”
Visitor Statistics and Comparisons
Glen Canyon NRA, which spans 1.25 million acres across Arizona and Utah, welcomed over 5.2 million recreational visitors in 2023. Popular attractions within the area include Lake Powell and Horseshoe Bend, which is renowned as one of the world’s most beautiful places according to CNN Travel.
Historical Context
Collapses of iconic rock formations are not uncommon. For instance, Taiwan’s renowned Elephant Trunk Rock fell into the sea late last year, underscoring the natural instability of seemingly sturdy rock features popular with tourists.
Conclusion
The collapse of the Double Arch serves as a stark reminder of the dynamic and often unpredictable nature of geological formations. As visitors and officials reflect on this event, the focus remains on balancing tourism with the preservation of natural resources.
