All but one person missing after flash flooding in parts of the Grand Canyon has now been found, the National Parks Service (NPS) has confirmed. Incident Commander Dave Black stated on Monday that rangers had worked to reduce the number of unaccounted individuals from 30.
At least two adult males died after floodwaters struck on Saturday afternoon, destroying footbridges and moving boulders downstream. One body, identified as a 46-year-old man, was found near Crystal Rapids along the Colorado River.
Dozens of people were airlifted from Phantom Ranch, one of the hardest-hit areas. An initial 45 people were evacuated by air on Saturday, followed by another 37 on Sunday afternoon.
Crews are being deployed on Tuesday morning to search for the final missing person in the area between Phantom Ranch and Cottonwood Manzanita. Further heavy rain was forecast overnight from Monday into Tuesday, raising the risk of additional flash flooding.
The flooding, described as "significant" by the NPS, began in Bright Angel Canyon around 14:30 local time (19:30 BST) on Saturday. Preliminary assessments indicate that about 40% of the Transcanyon Waterline, which supplies water to visitors and residents, was damaged or destroyed.
