Group of 4 friends went on the raft trip on September 25 and flipped on the quarter mile level 4 rapid. All 4 friends and guide flipped out of boat. All were rescued at various times but the last person lost her PFD after being flipped in the rapids. She was rescued by another raft group/guide . She was assisted up the incline toward he train tracks when an active train came by and all of the victims of the raft had to seek safety on the side of the track. A van from USA rafting came to pick up all the the friends after they walked approximately a mile down the track.
