20 People Reported Missing After Flash Flooding Hits Grand Canyon National Park

Air evacuations continued at the Grand Canyon in Arizona on Sunday afternoon, a day after a “significant flash flood” swept through campgrounds and hiking trails at the bottom of the national park, authorities said.

The Grand Canyon National Park Service said in a statement Sunday afternoon that it is asking the public to provide information for more than 20 individuals “who may be missing or unaccounted” following Saturday’s flash flood.

“The National Park Service is asking anyone who knows of hikers or backpackers who were in the inner canyon along the Bright Angel Creek corridor on August 29, as well as anyone who had a campground reservation in the affected corridor, to provide information to the National Park Service Investigative Services Branch (ISB),” the statement said.

Two helicopters from the Park Service and the state’s Department of Public Safety searched the North Kaibab Trail corridor as well as the Colorado River from the mouth of Bright Angel Creek to the Deer Creek Narrows on Sunday morning, Ms. Baird said.

“No missing individuals were located during these flights,” she said.

At least 62 people were evacuated from the tourist spot after the flooding caused significant damage on Saturday afternoon, park officials said in a separate statement.

Those who were evacuated were transported to the Maswik Lodge food court on the South Rim, where the American Red Cross was helping. No injuries have been reported, park officials said.

“Nearly all footbridges spanning Bright Angel Creek were destroyed, eliminating pedestrian access across the creek,” the Park Service said.

Officials warned of additional thunderstorms and heavy rainfall on Sunday and Monday that “could result in additional flash flooding, debris flows, rockfall and changing trail and river conditions.”
