GRAND CANYON, Ariz. — Two people are confirmed dead and one remains missing after flash flooding tore through Grand Canyon National Park's Bright Angel Canyon and Phantom Ranch area, according to the National Park Service. The toll marks a sharp narrowing from the days immediately after the flood, when officials said more than 20 people could be missing or unaccounted for.
The flooding struck around 2:30 p.m. local time on August 29, sending a surge of water, mud, boulders and debris down Bright Angel Creek. A National Weather Service meteorologist in Flagstaff said about half an inch to an inch of rain fell within roughly 30 minutes over the steep, rocky terrain, enough to trigger a fast-moving flash flood.
Search and Recovery Efforts
The body of a 46-year-old man was recovered Sunday evening near Crystal Rapids along the Colorado River. A second body was recovered Monday afternoon. Neither victim's identity had been officially released by the park service as of the latest update.
In the immediate aftermath, the National Park Service said more than 20 people might be missing or unaccounted for, based on incomplete information about who had been hiking or camping in the affected corridor. That figure was revised down to about 15 by Sunday afternoon as rangers and Arizona authorities worked through evacuation lists and outreach to hikers' families. By Tuesday, officials said nearly everyone had been located, leaving one person still missing. Search teams, including four with dogs trained for recovery work, were expected to continue operations Tuesday.
Evacuations and Infrastructure Damage
A total of 82 people were caught in the canyon when the flooding hit the Phantom Ranch area, Bright Angel Creek corridor and Cottonwood Campground. All were evacuated, most by helicopter, with 45 airlifted out by sunset Saturday and another 37 by Sunday afternoon. Park officials said all park employees in the area were accounted for and safe.
The flood caused extensive damage to infrastructure throughout the inner canyon. Nearly all footbridges spanning Bright Angel Creek were destroyed, cutting off pedestrian crossings, and sections of trail were washed out. The Transcanyon Waterline, the park's sole 12.5-mile pipeline supplying water from the canyon to both rims, suffered damage to roughly 40 percent of its length and is not currently operational. That forced the park to impose Stage 4 water restrictions on the South Rim starting August 31, closing all in-park overnight hotel accommodations, limiting South Rim campgrounds to dry camping, and banning wood and charcoal fires.
Phantom Ranch, including its canteen and cabins, Bright Angel Campground, the North Kaibab Trail and the Black and Silver bridges remain closed until further notice. River crossings near the affected area were also shut while damage is assessed, though rafting trips on the Colorado River elsewhere in the canyon later resumed after officials determined conditions were safe. The park itself remains open and accessible from both the North and South rims.
Monsoon Season Hazards
The National Park Service has warned that additional thunderstorms and heavy rainfall could bring further flash flooding, debris flows and rockfall to the area in the coming days, and has asked visitors to stay alert to canyon weather conditions.
The flooding coincides with Arizona's summer monsoon season, when a seasonal shift in wind patterns draws warm, moist air north from the Gulf of California and the tropical Pacific, fueling intense afternoon thunderstorms over the region's mountainous terrain. Inside the Grand Canyon, narrow drainages and steep elevation changes can turn even brief, localized downpours into fast-rising floods within minutes, often with little warning for hikers in the inner canyon.
The National Park Service continues to ask anyone with information about hikers or backpackers who were in the Bright Angel Creek corridor, the North Kaibab Trail, Cottonwood Campground or the area known as "the Box" on August 29 to contact its Investigative Services Branch tip line.
