i'd recommend poking around nwac's site for a bit
in the summaries, you can read things like "5 snowmobilers caught in avalanche, 2 wearing beacons"
http://www.nwac.us/accidents.htm
this will give you an idea about how many people were even expecting an
avalanche (id assume a BC skier at least has a thought about avy
occurance vs.
http://www.nwac.us/education_resources/statistics/us_avi_fatal_by_activity_from_1997.htm
avalanche.org also has fairly up-to-date stats on slides and deaths. their forecasts are colorado-oriented.
http://www.avalanche.org/av-reports/index.html
also remember that patrols is handing out the packs. i would assume
theyd ask a few questions. both because theyd want to know the snow
science knowledge of who is taking the packs. and also can you imagine
the lawsuit if someone with a borrowed pack got killed in an avy?
the dude with the awesome glasses on the alpy BC card
actually does not instantly stablize the snowpack as i ski over it.
on the education versus deaths.....i honestly don't think they track
that. because i've asked before. patrollers die on AC duty taking
every precaution. thats different than some person fresh out of an REI
avy class assuming that a piece of paper makes them invincible. and
last year in montana i think, some people high on a ridge cut the slope
burying some people skinning up the valley. people with the certs and
education are more likely to be in the dangerous situations anyways
than joe weekender. which probably skeews the statistics heavily in
favor if you are wearing a beacon you are more likely to die in an
avalanche.
and the famous quote "the avalanche does not care if you are an expert"
