COMMON ERRORS

 Wrong stability evaluation – in one study, over a five-year period, over 60% of avalanche fatalities were the result of wrong stability evaluation.

 Triggering the avalanche – most skiers caught in avalanches triggered the avalanche themselves.

 Taking uneccesary risks – in particular being on the wrong terrain and discounting evidence of snow instability that was contrary to what the skiers wanted to believe.

 Avalanching other members of the same group by triggering a slope above others.

 Failure to snow profile – weak layers that were easily triggered went undetected.

 Failure to identify dangerous accumulations of wind slab or appreciate the importance of past weather conditions.

 Triggering a small avalanche which in turn triggers a major slope failure. Failing to realise that in a snowpack of medium hardness large avalanches may occur.

 Triggering spontaneous and rapid release on sun-exposed slopes.

 Triggering a release from couloirs after small changes in temperature, wind or sun angle.
