A beloved geological landmark in southern Utah, also known as the Double Arch, Hole in the Roof, and sometimes called the Toilet, recently collapsed. This striking landmark, located in the Glen Canyon National Recreation Area, collapsed without causing any reported injuries.

Citing this, the National Park Service (NPS) indicated that changing water levels and erosion from wave action in Lake Powell may have played a significant role in this unfortunate event.

The double arch, which was a fine example of nature's sculpting skills, was carved from Navajo sandstone, which is approximately 190 million years old, they add in messages. Dating from the Late Triassic and Early Jurassic periods, this sandstone has withstood numerous environmental challenges over thousands of years, including wind, rain and temperature fluctuations. However, the recent collapse highlights how natural processes combined with human factors can influence these geologic wonders.

Michelle Kearns, superintendent of the Glen Canyon National Recreation Area, emphasized the importance of conserving the region's mineral resources. “These features have a lifespan that can be affected or damaged by human intervention,” she said. Kerns emphasized that while the exact cause of the collapse is still under investigation, the event serves as a poignant reminder of the need for conscientious conservation practices.

Spread over nearly 2,000 square miles, the National Glen Canyon Recreation Area attracts many visitors each year, drawn by its expansive landscapes and hiking trails. The Double Arch, with its distinctive formations, was a particularly popular spot for both casual visitors and avid photographers. Its collapse is the loss of a unique natural feature, which also highlights the need to increase awareness of the fragility of such formations.

NPS suspects changes in water levels and the erosive force of waves from Lake Powell combined with a natural process spalling and erosion contributed to the collapse of the arch. These factors, along with weathering over time, compromised the structural integrity of the sandstone arch. Kearns urged visitors to respect and protect the area's natural resources, advocating a "leave no trace" philosophy. “While we do not know what caused this collapse, we will continue to support our efforts to protect the resources of Lake Powell for future generations,” she added.
