Observe the phenomena

-Observe the different and varied avalanche phenomena (type of avalanche, starting zone, flow, deposition zone, etc...)
-Try to analyse the triggering causes (natural or induced)
-This method enables one to widen experience and deepen knowledge.

Gathering information (ARB {Avalanche Risk Bulletin}, weather forecast, talks, etc?) is essential, but insufficient. One must make one´s own risk assessment. To do that, the following three main factors must beconsidered:

. Snow and meteorological conditions: ARB, weather forecast, information from professionals, stratigraphic profiles, height of fresh snow, wind, temperature, surface state of snow, obvious phenomena, noises, snow cover analysis, slip tests, etc...

. Topography of the terrain: map study, talks from guides, photos, slope and micro- relief inclines on which one is skiing, observation of uphill slopes, unfavourable profile (convex), various objective dangers, potential damage in case of avalanche, slope orientation ...

. The human factor (very important!): oneself, those with whom one is skiing, but also those who might be near us, or who are watching; beyond the vital physical and technical aspects, the psychological behaviour of individuals or of groups must be known.
