Scott Flavelle will trace the history of avalanche damage to the Alcan transmission towers and the various mitigation methods recommended by our avalanche forefathers since the powerline was first built in 1953 to two recent tower failures in 1992 & 1993. Hector MacKenzie will then describe his psychological epic of being trapped by weather in a plywood coffee shack in a large avalanche track with modern linesman while avalanches are running...
