SALT LAKE CITY (AP) — The recent collapse of a popular rock arch at Lake Powell known as the “Toilet Bowl” is a sad reminder that the spectacular geological arches that dot southern Utah’s landscape aren’t guaranteed to be there forever. Arch experts say erosion and human activity mean that arches are susceptible to crumbling at any given time. Parks officials have been fielding questions this week about the fragility of Utah’s arches in light of the recent collapse. They aren’t physically fortifying the arches but have strict policies to limit human impact. A Utah geologist has found that human-made energy sources such as trains, trucks and helicopters are increasing ground vibrations and placing stress on arches.
