Event narrative (NOAA)
Multiple rounds of heavy rainfall brought flash flooding to Zion National Park, including along North Creek, but the most notable flood occurred in Keyhole Canyon. A group of seven people entered Keyhole Canyon in the early afternoon, planning to travel through the small but popular canyoneering route. Flooding in Keyhole Canyon occurred quickly; no one in the group was able to escape the canyon or get to higher ground, and the flood killed all seven individuals. The seven victims were between 51 and 59 years old.
