One still missing after Grand Canyon floods kill two and prompts rescue efforts

Key Points:

• The National Parks Service (NPS) has found all but one of the 30 people initially missing after flash flooding devastated parts of the Grand Canyon, with search efforts ongoing for the final individual between Phantom Ranch and Cottonwood Manzanita.
• At least two adult males died when floodwaters struck on Saturday afternoon, destroying footbridges and causing boulders to move downstream; one body was found near Crystal Rapids along the Colorado River.
• Rescue operations included airlifting 45 people on Saturday and evacuating another 37 by Sunday, focusing on Phantom Ranch, one of the hardest-hit areas, which along with other sites remains closed due to damage.
• The flooding, which began around 14:30 local time on Saturday in Bright Angel Canyon, caused significant infrastructure damage, including about 40% destruction of the Transcanyon Waterline that supplies water to visitors and residents.
• The recent heavy rains and flash flooding were driven by monsoonal weather patterns typical for this time of year, bringing warm, moist air from the Gulf of California and the tropical Pacific to the region.
