The survival rate of victims caught in an avalanche declines with every minute spent buried beneath the snow.
The Canadian Avalanche Centre reports almost three quarters of all avalanche deaths are due to suffocation, most often because the victims simply weren't found in time.
In the mountains near B.C.'s Kootenay pass, avalanche technician Robb Andersen tells Kelsey McEwen fifteen minutes is the time rescuers have to pull someone out from the snow.
"Your friend goes down in an avalanche and you can imagine the stress involved just in that," he says. "You've got to get all your gear out, you have to get it in your head exactly what you're going to do, turn on your transceiver, get out there, search and then dig. Well, how long is all that taking?"
Quick thinking by travel companions, say experts, is the key to survival, along with having the right gear.
It's recommended everyone in a group wear some kind of transceiver when travelling, which can be used to point the way to buried companions.
Rescue dogs are another option. To demonstrate, McEwen was buried inside of a snow bank, while retired rescue dog Aquillo was set on the scent.
The pooch found McEwen in just a few seconds but, in reality, only one person has even been found alive by a rescue dog in Canada.
Statistics for other rescue efforts are more optimistic but, in every case, time is crucial.
McEwen was in B.C., along with Weather Network meteorologist and storm hunter Mark Robinson, and storm chaser George Kourounis, to capture footage
of controlled avalanche work.
