I am wondering if anyone here knows how to contact Tom's family? Tom was on his way up to the Canadian Rockies to spend a second winter climbing with Ken Wallator when he stopped off to climb Triumph. I have several images of Tom from his time climbing here in Canada, including his and Ken's FA of the North Face of Storm in winter. Ken was never certain exactly what happened to Tom, the mechanics of how he fell. He had heard that Tom's harness was still attached to the rope, just no body in it. Does anyone know if this is true, or can anyone fill in more details about what they believe happened?
