Dr. John Giusti and Brent Rosenkranz confirmed dead after flash floods strike Grand Canyon National Park

Timothy Allen Smith, who was with the pair, is still being searched for by rescue teams. Search efforts are being conducted by the National Park Service in partnership with the Coconino County Search and Rescue Team and the Border Patrol Search, Trauma, and Rescue Unit. Teams are utilizing dogs, boats, helicopters, and drones to scour debris-flow areas. The flooding caused extensive damage to infrastructure, including the destruction of nearly all footbridges spanning Bright Angel Creek. The Transcanyon Waterline, which serves the park and nearby residents, was damaged by approximately 40%, leading to Stage 4 water restrictions for the South Rim. The park has closed all overnight hotel accommodations until further notice. Visitors are advised to stay away from the closed areas, including the North Kaibab Trail and Phantom Ranch. The flooding was exacerbated by a lack of vegetation in the Dragon Bravo fire scar, which allowed runoff to flow more quickly through the scenes.
