A major flash flood at the Grand Canyon forced the evacuation of more than 60 people and swept large boulders, metal structures and other debris into the Colorado River, the National Park Service said.The flash flooding occurred Saturday afternoon in Bright Angel Creek, which flows into the Colorado River. Torrents of water destroyed footbridges over the creek and significantly changed the landscape, widening the creek bed and creating what appeared to be a new rapid in the river.🇺🇸: Flash floods sweep Grand Canyon, 62 evacuated and more than 20 still missing.A flash flood hit Bright Angel Canyon and Phantom Ranch at Grand Canyon National Park on Aug. 29, 2026.
