More than 20 people remain unaccounted for after a powerful flash flood tore through Grand Canyon National Park’s Bright Angel Canyon on Saturday, August 29, 2026. Park authorities and the Arizona Department of Public Safety have airlifted at least 62 campers and hikers to safety while closing multiple trails and crossings.
A major flash-flood event struck the remote inner corridor of the Grand Canyon on Saturday afternoon, dropping rapid downpours over recently burned terrain. The sudden deluge sent a destructive slurry of mud, large boulders, and debris rushing toward the Colorado River.
Most of it ran off instantly,
National Weather Service meteorologist Justin Johndrow said, explaining that storms dropped about half an inch to an inch of rain within roughly 30 minutes in a rocky area where the terrain drops in elevation by about 6,000 feet from the North Rim down to the Colorado River.
Search and Evacuation Efforts Along Bright Angel Creek
Emergency response operations ramped up as authorities worked to account for hikers and backpackers caught in the path of the floodwaters. According to Grand Canyon National Park staff, in coordination with the Arizona Department of Public Safety, evacuation and response efforts continued through the weekend. Park officials urged anyone with information about visitors who were in the affected corridor on Saturday to contact authorities.
The search centers on the Bright Angel Creek corridor, the Bright Angel Campground, and campground reservations in the inner canyon. Investigators are also trying to trace individuals who may have been traveling along the North Kaibab Trail between the trailhead and Phantom Ranch, or staying in an area known as the Box
north of Phantom Ranch.
Infrastructure Damage at Phantom Ranch and Trail Closures
The floodwaters severely altered the landscape, wiping out infrastructure across the historic canyon bottom. Torrents of water significantly altered the landscape, widening the creek bed and creating what appeared to be a new river rapid near Phantom Ranch. Nearly all footbridges spanning Bright Angel Creek were destroyed, eliminating pedestrian access across the creek.
Images shared by park authorities showed a metal building washed into the Colorado River and multiple bridges swept away. A U.S.
Park officials ordered the indefinite closure of Phantom Ranch, the Bright Angel Campground, the Phantom Ranch canteen and cabins, and the entire North Kaibab Trail from the trailhead down to Phantom Ranch. The Black Bridge and Silver Bridge river crossings are also closed until further notice, and Colorado River traffic was shut down due to the risk of floating debris.
Survivor Accounts of the Sudden Deluge
Campers caught in the inner canyon described the rapid onset of the disaster. Erica Viola recounted being at the Bright Angel Campground when the rain began Saturday afternoon, watching the creek swell and debris sweep past, including what appeared to be a bunkhouse.
David Gregory told CNN he was hiking with a small group when the rising waters cut their trip short. We realized the creek near camp was black with debris and flowing rapidly,
he said. His group was subsequently evacuated by helicopter, taken to a local high school, and provided lodging for the night.
“This is a reminder of what a dynamic and active landscape [the] Grand Canyon is.”
