PAGE, Ariz. — A large geological feature in southern Utah known as the “Double Arch,” the “Hole in the Roof” and sometimes the “Toilet Bowl” has collapsed, National Park Service officials said Friday.
The popular arch in the Glen Canyon National Recreation Area fell Thursday, and park rangers suspect changing water levels and erosion from waves in Lake Powell contributed to its demise.
Michelle Kerns, superintendent of the recreation area that spans the border of Utah and Arizona, said the collapse serves as a reminder to protect the mineral resources that surround the lake.
The arch was formed from 190 million-year-old Navajo sandstone originating in the late Triassic to early Jurassic periods.
The recreation area encompasses nearly 2,000 square miles and is popular among boaters and hikers.
