Avalanches are not rare or random events. Most common during winter and spring, avalanches can occur any time of the year, and they are among the most threatening natural hazards to life and property in mountainous terrain.
Spontaneous avalanches result from either a weakening of a snowpack and gravity or an increased load on it due to precipitation. Avalanches are also triggered by disturbances from skiers, snowmobilers, animals, and seismic activity. A loud noise or shouting, however, is not a trigger as commonly believed unless the sound comes from an explosive device (frequently used to prevent avalanches in at-risk areas by triggering a small avalanche to remove instabilities in a snowpack).
If you ski, board or ride in the backcountry, live in or travel through snow covered mountainous terrain, the threat of avalanches must not be ignored as the dangers are very real.
This too real video by TahoeChappy captures the frightening experience of a backcountry skier as he triggers an avalanche, is buried and miraculously dug out in 4 minutes/28 seconds. He got very lucky. Not everyone gets that kinda luck.
In North America, 42-45 people on average are killed by avalanches (more than 150 worldwide), and hundreds more are injured. Most are snowmobilers, skiers, and snowboarders. Sobering reminders that whether you’re a backcountry expert or newbie, don’t venture out without understanding and preparing for the dangers. The good news — there are many resources available to help you learn how to reduce the risks.
