Eric Harmon is visiting his salmon fisherman Uncle Larry and his wife, Olga, in beautiful British Columbia. He discovers a mysterious totem pole in the woods and soon teams up with a Northwest Native American girl, Jenny Whitefeather, to try to discover the pole's story, which seems to be buried in ancient Salish Indian tribal lore. The two youngsters run afoul of two American marijuana growers who try to kill them. In the end, the bad guys are caught by the Mounties, and the mystery solved, with the help of an oceanographic analysis scientist at the Victoria, British Columbia Museum. -- 150 years earlier the tribe was nearly wiped out by a huge tidal wave. The two youngsters vow to team together next summer to solve a new mystery.
