Last Monday?No one reported observing the arch collapse and there were no visitor injuries, the National Park Service said.
Geologists from the Park Service's Geologic Resources Division and the Utah Geologic Survey visited the site Thursday and noticed obvious stress fractures in the remaining Wall Arch formation, spokesman Paul Henderson said in a statement. Rock debris completely blocked a section of the trail about a mile from the Devils Garden parking area.
Wall Arch, located along the popular Devils Garden Trail, was 71 feet tall and 33 1/2 feet wide, ranking it 12th in size among the known arches inside the park. Lewis T. McKinney first reported and named Wall Arch in 1948.
The arch was simply a victim of erosion & gravity.
