GRAND CANYON VILLAGE, Ariz. — Rescue teams ramped up search efforts Monday for roughly 15 people still unaccounted for after a devastating flash flood tore through a popular section of Grand Canyon National Park, claiming at least one life. The deluge, which struck Saturday along Bright Angel Creek, also knocked out the canyon's only water pipeline, forcing emergency water restrictions for year-round residents and barring tourists from overnight stays inside the park.
The National Weather Service said four separate "waves of rainfall" over two creek drainages triggered the rapid flooding, which sent a muddy, debris-laden surge through the area, carrying rocks and what appeared to be remnants of a bunkhouse. Video from the scene showed the sheer force of the water as it swept through the narrow canyon.
Paige Konieczny, a meteorologist with the weather service in Flagstaff, Arizona, cautioned that more thunderstorms and showers are expected Monday, adding that the region's monsoon season — which brings sudden, intense downpours — remains a serious threat. "With it being in the location that it is, it's only going to add to our concern with flash flooding," she said.
The floodwaters also hit part of the Dragon Bravo fire scar, a burn area left by a lightning-caused wildfire in July 2025 that scorched more than 227 square miles. That fire, which forced evacuations and destroyed the historic Grand Canyon Lodge and other structures, has left the landscape more vulnerable to runoff, heightening the flood risk.
Officials recovered the body of a 46-year-old man Sunday evening near Crystal Rapids along the Colorado River, the National Park Service reported, though they did not provide further details. More than 60 people were airlifted from the depths of the canyon, and the Arizona Department of Public Safety assisted with evacuations Sunday. The park service has asked anyone with information about hikers or campers still missing to come forward.
The incident underscores the dangers of visiting the Grand Canyon during the summer, when clear skies can quickly turn into violent thunderstorms. The area receives less than 10 inches of rain per year on average, making such flash floods particularly hazardous. The first three waves of rain "primed the drainages and already had creeks flowing at minor levels" by the time the fourth arrived, the weather service noted.
As the search continues, officials are urging visitors to heed weather warnings and avoid canyon areas prone to flooding. The park has imposed emergency restrictions, and the timeline for restoring the water pipeline remains unclear. The broader implications for park operations and tourism are still being assessed.
This disaster comes amid a series of extreme weather events across the region, including recent flash floods in Nepal that left dozens missing and killed hundreds. While the situations are distinct, they highlight the growing risks of sudden flooding in mountainous terrain.
