I've read up quite a bit on this crash as it happened just outside my hometown of Chilliwack, BC.
Unfortunately, the on-line write-up by the CFL/producers states the crash was in the Rockies. It was on Mt. Slesse, which is in the Coast Mountains. A common mistake that appears because so many people equate ALL BC mountain ranges with the Rockies. Too bad a factual error was made, but still a very compelling story.
