Kane, who lives in Poulsbo, was taking part Friday in a whitewater rafting trip sponsored by the Boy Scouts of America when he and his son were ejected from the raft in a stretch of the river known as "the Slide."
A guide with Epley's Whitewater Adventure, which was operating the raft, pulled Kane's son from the river then maneuvered to a back eddy below the Slide where Kane was found floating face down and unconscious.
The guides and several passengers who had training as first responders immediately began CPR. They continued resuscitation efforts as they made their way to confluence of the Salmon and Snake Rivers where they were picked up by a passing jet boat.
Kane was eventually picked up by a medical airlift helicopter and taken to St. Joseph Regional Medical Center in Lewiston, Idaho, where he was pronounced dead.
A 23-year veteran of the Seattle Fire Department, Kane was currently stationed at West Seattle Fire Station 36. Lt. Kane is survived by his wife and 2 children.
