A massive search-and-rescue operation is underway at Grand Canyon National Park after a violent flash flood ripped through Bright Angel Canyon and the Phantom Ranch area.
The flooding left at least one person dead and approximately 15 hikers or campers missing or unaccounted for as emergency crews battle some of America’s most unforgiving terrain.
The disaster erupted Saturday after powerful monsoon storms dumped heavy rain across the region, sending a dangerous surge of water, mud, rocks, and debris through Bright Angel Creek and devastating infrastructure deep inside the canyon.
The National Park Service said Sunday that approximately 15 individuals may still be missing or unaccounted for and appealed directly to the public for help determining who was traveling through the affected area on Aug. 29.
Grand Canyon National Park personnel have continued evacuation efforts while working alongside the Arizona Department of Public Safety and other state and local emergency responders to account for everyone believed to have been inside the canyon when the flooding struck.
Authorities are specifically seeking information about hikers and backpackers who may have traveled the North Kaibab Trail toward Phantom Ranch, stayed at Bright Angel Campground or passed through the narrow section north of Phantom Ranch known as “the Box.”
The Park Service asked anyone with useful information to contact its Investigative Services Branch and provide names, approximate locations, travel plans, group sizes, clothing or backpack descriptions and the last known whereabouts of potentially missing individuals.
More than 60 people were ultimately airlifted from the depths of the canyon as helicopters became a critical lifeline for visitors stranded by destroyed crossings, damaged trails, and the rapidly changing conditions below the rim.
Former FEMA External Affairs Officer Jason Peck told CNN that the rugged landscape creates enormous difficulties because rescuers often cannot reach victims by conventional vehicles and instead must depend on narrow pathways and aircraft.
Peck described the operation as “extremely challenging,” while stressing that officials were referring to the missing hikers as “unaccounted” — terminology that leaves open the possibility some people are alive but unable to communicate because of the Grand Canyon’s notoriously poor cellular coverage.
The emergency took an even darker turn when the National Park Service confirmed that rescuers recovered the body of a 46-year-old man Sunday evening near Crystal Rapids along the Colorado River, establishing the first known fatality from the flood.
The man’s identity and additional details surrounding his death were not immediately released as authorities remained focused on finding those who were still unaccounted for and evacuating others from hazardous areas.
Images emerging from the canyon revealed extensive destruction, including obliterated footbridges, damaged trails, widened waterways, and enormous amounts of debris carried through Bright Angel Creek toward the Colorado River.
Officials shut down Phantom Ranch, Bright Angel Campground, the Phantom Ranch Canteen, the North Kaibab Trail, the Black and Silver bridges, and access toward the Colorado River in the impacted section, with no immediate reopening date announced.
The flood also destroyed the Grand Canyon’s only water pipeline, creating another serious crisis by forcing emergency conservation measures for approximately 1,600 year-round Grand Canyon Village residents and preventing tourists from staying overnight at hotels and lodges inside the park.
The pipeline disaster represents a painful setback for an already expensive federal infrastructure project, as a $208 million rehabilitation of the aging pipeline and associated water-delivery system began in 2023 and had been expected to reach completion next year.
Flash floods are a particularly serious threat during Arizona’s summer monsoon season because storms can develop quickly and dump tremendous amounts of water into narrow canyon channels even when conditions elsewhere initially appear manageable.
Federal, state, and local responders are now pressing ahead through washed-out crossings, unstable terrain, and continued weather threats, with helicopters and ground teams working to locate every missing person possible while authorities urge anyone with information about hikers in the affected corridor to come forward immediately.
