There is a small Canadian Forces detachment positioned in Roger's Pass, which, as it is only the Canadian Forces who can legally operate howitzers and such, triggers avalanches. This film is from April 3, 2010.
These are avalanches that might hit the Trans-Canada Highway or the railway lines where they are exposed, not the back country avalanches set off by skiers and snowmobilers that kill so many people each winter.
