Kathmandu— More than 60 people have been evacuated and at least 15 are feared missing following a significant flash flood that swept large boulders and debris into the Colorado River in the Grand Canyon, according to the National Park Service. The flooding occurred on Saturday afternoon in Bright Angel Canyon and Phantom Ranch areas of Arizona's Grand Canyon.

Impact of Flash Flood

The flash flood swept large boulders, metal structures, and other debris into the Colorado River, wiping out footbridges over Bright Angel Creek and significantly altering the landscape. The creek bed was widened, and a new river rapid appeared as a result of the flooding.

Evacuations and Search Efforts

As of Sunday morning, 62 people were evacuated from the affected areas. The National Park Service is asking for public assistance in locating approximately 15 individuals who may be missing or unaccounted for following the flash flood event. Additional evacuations are planned on Sunday.

Park Closures and Safety Measures

Popular tourist spots such as Bright Angel Campground, Phantom Ranch, and parts of the North Kaibab trail remained closed on Sunday while park officials surveyed the damage. Rafting trips on the Colorado River have also been halted for now.

The Grand Canyon National Park Service is working in coordination with the Arizona Department of Public Safety to manage the situation, and more rain and thunderstorms are forecasted for the area into Monday.
