More than 20 people are missing or unaccounted for after a severe flash flood struck Grand Canyon National Park in the US state of Arizona on 29 August, according to the US National Park Service. Search and evacuation operations are ongoing as authorities work to locate individuals who were in the affected inner canyon corridors at the time of the disaster.
What Happened
The US National Park Service described the event as a 'significant flash-flood event' that struck Bright Angel Canyon and the Phantom Ranch area on Saturday local time. The agency issued a public call on Sunday urging anyone with knowledge of hikers or backpackers who were in the inner canyon along the Bright Angel Creek corridor on 29 August — or who held campground reservations in the affected area — to contact the National Park Service Investigative Services Branch immediately.
Evacuations and Current Status
As of the morning of 30 August, 62 individuals had been evacuated from Phantom Ranch and the lower North Kaibab Trail. Evacuees are being transported to the Maswik Lodge Cafeteria on the South Rim, where the American Red Cross is coordinating relief assistance. Park officials confirmed that no injuries had been reported as of the latest available information.
Infrastructure Damage
The flash flood caused significant damage to infrastructure throughout Bright Angel Canyon. According to officials, almost all footbridges spanning Bright Angel Creek were destroyed, cutting off hiker access across the creek. Grand Canyon National Park staff are continuing to assess damage to trails, bridges, utilities, facilities, and other infrastructure throughout the corridor.
Fresh Flood Warning Issued
Authorities have issued a thunderstorm and heavy rainfall warning for Monday, cautioning that additional flash flooding, debris flow, rockfall, and rapidly changing trail and river conditions remain possible. Park officials are coordinating response efforts with the Arizona Department of Public Safety. The warning adds urgency to ongoing search operations, as deteriorating weather could hamper rescue access to the remote inner canyon.
This is not the first time the Grand Canyon's inner corridor has been struck by flash floods — the narrow canyon geography and monsoon-season weather patterns make the area particularly vulnerable each summer. With search operations still active and fresh storms forecast, the full scale of the incident may not be known for several days.
Point of View
The window for search operations is narrow. The National Park Service's public appeal for information on missing hikers also signals that its own visitor-tracking systems were insufficient to account for everyone in the corridor — a systemic gap worth scrutinising as summer crowds grow year on year.
