The collapse of Double Arch in Utah’s Glen Canyon National Recreation Area stunned visitors and deprived the state of a natural landmark. Geologists say the arch’s demise was inevitable due to erosion since its formation 190 million years ago. Changes in water levels, wind, and weather conditions also likely contributed to the collapse. Double Arch was at the end of its life cycle, with a weak lintel structure that made it more susceptible to collapse. Human activity near the arch may have hastened its demise, although the exact extent is unclear. Climate change may have played a role, but geologists say it is hard to determine a direct connection. Other arches in Arches National Park, including Wall Arch and Rainbow Arch, have also collapsed in recent years due to erosion and decay. Landscape Arch, the longest arch in North America, is also aging and could be at risk of collapse. Geologists see the constant erosion and decay of these geological structures as part of their beauty and natural life cycle. Despite the loss of Double Arch, visitors can still appreciate the ever-changing landscape of the national parks in Utah.
