Flood strikes Bright Angel Canyon and Phantom Ranch
The flash flood hit Bright Angel Canyon and the Phantom Ranch area of the Grand Canyon on Aug. 29. The affected location is in the inner canyon, where visitors use trails, campgrounds and facilities near Bright Angel Creek. Floodwater and debris moved through the corridor, creating dangerous conditions for people in the area and prompting an emergency response by park personnel and state authorities.
The National Park Service described the flooding as significant. Nearly all footbridges crossing Bright Angel Creek were destroyed, according to the agency, leaving key routes damaged and making movement through the area more difficult.
Evacuations continue as officials assess the area
Park officials said 62 people had been evacuated from Bright Angel Canyon and Phantom Ranch by Sunday morning. The National Park Service and the Arizona Department of Public Safety were continuing evacuation and response operations while working to determine who had been in the affected area.
The scale and remoteness of the canyon are complicating the response. Crews must assess damaged trails and crossings while managing debris and muddy water. Officials said additional evacuations were planned, indicating that the operation remained active after the initial group of visitors was moved to safety.
Public asked to help identify people in the canyon
The National Park Service is asking anyone with information about hikers or backpackers who were along Bright Angel Creek on Aug. 29 to contact investigators. The request also includes people who held campground reservations in the affected area.
Officials are particularly seeking information about visitors who may have been traveling on the North Kaibab Trail between the North Kaibab Trailhead and Phantom Ranch, staying at Bright Angel Campground or moving through the area known as the Box north of Phantom Ranch. The agency has not released details about the more than 20 people who may be unaccounted for, including whether they were hikers, campers or visitors with reservations.
“Additional evacuations are planned today,” the park said, warning that more thunderstorms and heavy rain could bring further flash flooding, debris flows and rockfall.
Flood damage complicates travel and rescue operations
The destroyed footbridges across Bright Angel Creek are among the most significant reported effects of the flood. Their loss can disrupt ordinary access between trails, campsites and other facilities, while debris and standing muddy water can conceal hazards and damage.
Response teams are working both to evacuate visitors and to account for people who may have been in the affected corridor. The park’s request for information is intended to help investigators compare known reservations and travel plans with the people already evacuated.
Further severe weather remains a concern
The threat did not end with the initial flood. The National Park Service warned that additional thunderstorms and heavy rain were possible on Sunday and Monday, conditions that could trigger more flash flooding, debris flows and rockfall in the canyon.
Those hazards could affect evacuation plans, trail access and the safety of response crews and visitors. People with information about anyone who may have been in the affected area can contact the National Park Service Investigative Services Branch Tip Line at 888-653-0009 or nps_isb@nps.gov.
