The pedestrian appeared to misjudge the speed of the water when he tried to cross Angel Falls in California, police said, and was trapped in cold springs that flow 50 to 80 feet per second.
Nearby, California Highway Patrol Officer Brent Donley, who is trained in search and rescue, is also hiking in the area near Bass Lake in Madera District.
Donley used a strap from his backpack and tied it around the branch so that the pedestrian could reach it, police said. He threw a branch at the man and then spoke to him through rescue, according to a video released by California Highway Patrol Fresno.
With the help of a group of other climbers, Donley pulled the man, who was not yet named, to a safe place. He gave first aid until the SAR officer arrived.
