Grand Canyon flash flood leaves 2 dead and several missing or unaccounted for, park service says

For Tucson residents planning a Grand Canyon trip, the immediate consequences of Saturday’s flash flood are significant. Two people are dead, about 15 others are missing or unaccounted for, popular inner canyon destinations remain closed, and overnight lodging inside the park has been suspended because the flood damaged the only water pipeline serving Grand Canyon Village. Park officials are asking anyone with information about hikers or campers who have not been located to contact authorities.

The National Park Service said flooding began around 2:30 p.m. in Bright Angel Creek, which runs from the North Rim down to the Colorado River. The water swept through the canyon with enough force to destroy footbridges, move large boulders into the river and reshape the creek channel. More than 60 people were flown out of the canyon, and the Arizona Department of Public Safety assisted with additional evacuations Sunday.

A 46 year old man’s body was recovered Sunday evening near Crystal Rapids along the Colorado River, according to the park service. Officials from an Arizona coroner’s office were present at the scene. By Monday, park officials said that two bodies had been recovered, but they did not release further information about the second recovery or provide details about the identities of those who died.

Bright Angel Campground, the North Kaibab Trail and Phantom Ranch were still closed Sunday. Phantom Ranch includes a historic canteen and dormitories, and the campground was occupied by roughly 50 hikers when the creek began rising. Erica Viola, one of those hikers, said she saw debris moving through the floodwaters, including what appeared to be a bunkhouse. A helicopter evacuation ended her trip two days earlier than planned.

Another hiker, Parth Desai, was traveling through a narrow section of Bright Angel Canyon with fellow physicians and a park ranger when the rain intensified. He described seeing the creek rise rapidly, waterfalls appear, and boulders, mud and landslides move through the canyon. Later, as the group approached the Phantom Ranch area, a roughly 4 foot wall of debris headed toward them. They climbed into an area of cacti and were rescued by helicopter late Saturday.

The storm developed under conditions that can make summer travel in the canyon especially hazardous. Darren McCollum, a National Weather Service meteorologist in Flagstaff, said between half an inch and 1 inch of rain fell in about 20 minutes on a steep, rocky slope. Two earlier weather systems had already saturated the ground. When the main storm arrived, the additional intense rainfall triggered the flooding. More rain and thunderstorms were possible through Monday.

The damage also threatens basic services for workers, residents and visitors. The broken pipeline is the sole water connection serving tourists and the roughly 1,600 year round residents of Grand Canyon Village. Because the park cannot replenish its potable water storage tanks on the South Rim while the pipeline is out of service, overnight stays at lodges and hotels inside the park were scheduled to stop Monday. Residents were asked to conserve water. Lodging remained available outside the park at the South Rim entrance area in Tusayan, a potential alternative for Arizona travelers whose plans were disrupted.

The pipeline failure adds another problem to a project already intended to address years of service interruptions. The park has been working since 2023 on a $208 million rehabilitation of the pipeline and related water delivery infrastructure. The National Park Service has described that work as essential for meeting the needs of the park’s visitors and residents, with completion expected next year. Jack Schmidt, director of the Center for Colorado River Studies at Utah State University, said the flood could create major financial and engineering challenges if portions of the system deep in the canyon must be rebuilt.

The Grand Canyon attracts about 6 million visitors annually, making the closures and water restrictions important well beyond the immediate flood zone, including for Arizonans traveling north from Tucson. Summer monsoon storms can turn clear conditions into dangerous flooding with little warning, especially in narrow canyon terrain. Search and evacuation operations were continuing, while officials sought information about people who might still be unaccounted for. The extent of the damage to trails, bridges, the river corridor and the water system will determine how quickly the affected areas can reopen.
