Footage captured the moment Russ Cole plunged into the White Salmon River and dragged the man to safety just seconds after his fall, preventing what could have been a terrible tragedy.Cole, a guide at Zoller's Outdoor Odyssey's which runs whitewater rafting trips, was sitting in a small boat as a group of four rafters dipped over the 14-foot Husum Falls on Tuesday, according to ABC News.But the force of the water was too much for two of the patrons, with one falling forward and knocking a man who wasn't properly holding a rope out of the raft.The unidentified adventure seeker then hit his head as he was dragged down the river by the strong current.Video captured by the tour company's cameras along the river showed Cole spring into action as the water raged around him.He jumped head-first into the river and within seconds, pulled the man to a rocky embankment.'It looks like it's happening really fast to other people,' Cole told ABC News. 'This is all slow motion for us.'
