A sudden flash flood tore through the Grand Canyon in Arizona on Saturday, leaving at least one person dead and multiple hikers missing in remote areas including Bright Angel Canyon and Phantom Ranch, according to the National Park Service. The disaster prompted emergency evacuations as roaring torrents of muddy water and debris damaged critical park infrastructure.
Fatalities and Search Operations in Remote Canyons
The National Park Service confirmed that a 46-year-old man died in the flooding, with his body recovered near Crystal Rapids along the Colorado River, according to regional reporting. Authorities have deployed search teams to locate backpackers, day hikers, and campers who may have been traversing the Bright Angel Creek corridor or staying at the Phantom Ranch and Bright Angel Campground.
Meteorological Causes Behind the Kaibab Plateau Storms
The flash flooding developed rapidly on Saturday afternoon following intense thunderstorms over the Kaibab Plateau. Darren McCollum, a meteorologist with the U.S. McCollum noted that earlier rainfall had already saturated the ground, leaving the landscape unable to absorb the subsequent torrid downpour and triggering catastrophic runoff into the canyon depths.
Infrastructure Damage and Evacuation Efforts
The rushing floodwaters destroyed pedestrian footbridges crossing Bright Angel Creek and heavily damaged the Transcanyon Waterline, a 20-kilometer pipeline that supplies the park. According to park administrators cited by Fox Weather and local reports, 62 people were safely evacuated from Phantom Ranch and the lower North Kaibab Trail by Sunday morning, while commercial river navigation on the Colorado River was temporarily suspended due to hazardous floating debris.
