A flash flood in the Grand Canyon National Park in Arizona has resulted in one death and approximately 15 people missing, following a similar incident in Nepal caused by a glacier collapse.
According to the Associated Press, the Grand Canyon area experienced heavy rainfall of up to 25.4 mm over a span of 20 minutes on the afternoon of August 29. The rapid influx of water quickly flooded Bright Angel Creek and the Phantom Ranch area.
Park authorities reported that about 15 individuals remain unaccounted for. A 46-year-old man was found dead near Crystal Rapids on the Colorado River that evening.
The sudden surge of water swept away a footbridge and surrounding structures across the canyon. More than 60 climbers and campers who were stranded at the site were evacuated using helicopters.
The flooding has also impacted park operations. Issues with the main water supply line have led to the suspension of lodging services at lodges and hotels starting August 31, and authorities have requested residents to conserve water.
The Grand Canyon has been undergoing a $20.8 million water infrastructure improvement project since 2023 to replace aging water lines, which was scheduled for completion next year.
The National Weather Service reported that the heavy rain was accompanied by thunderstorms, leading to rapid flooding. Most of the footbridge over Bright Angel Creek was destroyed, and some areas have seen changes to the terrain around the Colorado River.
There is a possibility of additional rain in the area until August 31, raising concerns about further damage. The National Park Service plans to close parts of Bright Angel Campground, Phantom Ranch, and the North Kaibab Trail while continuing evacuation efforts.
As of now, no casualties involving South Koreans have been reported.
