Park rangers suspect changing water levels and erosion to blame for the collapse of the popular tourist attraction

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 on Friday. No injuries were reported.

The popular arch in the Glen Canyon national recreation area fell on 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.
