PAGE, Arizona. A large geological formation in southern Utah known as the “Double Arch,” “Hole in the Roof” and sometimes “Bathroom” has collapsed, National Park Service officials said Friday. No injuries were reported.
The popular arch in Glen Canyon National Recreation Area fell on Thursdayand rangers suspect that changing water levels and wave erosion in Lake Powell contributed to its disappearance.
Michelle Kerns, superintendent of the recreation area that straddles the border of Utah and Arizona, said the collapse serves as a reminder to protect the mineral resources surrounding the lake.
“These characteristics have a lifespan that can be influenced or damaged by man-made interventions,” she said in a statement.
The arch was formed from 190-million-year-old Navajo sandstone that originated in the late Triassic to early Jurassic period. The fine-grained sandstone has been eroded by weather, wind and rain, the statement said.
The recreation area covers almost 5,180 square kilometers (2,000 square miles) and is popular with boaters and hikers.
