At least ۱۵ people may be missing or unaccounted for after a major flash flood swept through the Grand Canyon national park in Arizona on Saturday afternoon, according to the National Park Service.
The flash-flood event occurred in the area of Bright Angel Canyon and the Phantom Ranch, where park staff and the Arizona department of public safety have evacuated more than ۶۰ people as of Sunday morning.
No injuries have been reported as of Sunday, according to a statement from the National Park Service.
“Phantom Ranch, Bright Angel Campground, the Phantom Ranch Canteen and cabins, and the entire North Kaibab Trail from the North Kaibab Trailhead to Phantom Ranch are closed until further notice,” the statement said.
Park officials announced the number of people who remain missing or unaccounted for in a separate statement, requesting the public to notify the government agency of information they may know about “hikers or backpackers who were in the inner canyon along the Bright Angel Creek corridor” on Saturday, as well as “anyone who had a campground reservation in the affected corridor”.
Nearly all footbridges spanning Bright Angel Creek were destroyed, officials said, and the Colorado River is closed to river traffic until further notice as metal structures and debris enter the river.
About half an inch to ۱in (۱-۲.۵cm) of rain fell within about ۳۰ minutes in the rocky area where there is a steep drop in elevation, Justin Johndrow, a National Weather Service meteorologist in Flagstaff, told the Associated Press.
“Most of it ran off instantly,” Johndrow said.
He said the flooding happened on the north side of the Grand Canyon, where Bright Angel Creek comes from the North Rim down to the Colorado River, dropping about ۶,۰۰۰ft (۱,۸۰۰ meters).
More rain and thunderstorms were possible in the area into Monday.
