A Boulder the size of a refrigerator broke loose hitting 52-year-old David Finlayson and sending him careening 30 feet down the mountain, knocking him unconscious, breaking his back, left arm and heel, with the nearest ranger 13 miles away and no one around to help, it was all up to 13 year old Charlie to save his dad. Charlie was on top of things and got the first aid lowered to me. Reporter: For two and a half days the boy scout kept his dad calm and hydrated and caring for him. His dad finally sent him for help with this note explaining what happened and how to find him. Mostly I was scared I wasn't going to find anybody.
