In developed areas such as ski resorts it is possible to predict avalanches because they are controlled with explosives and artilley. In back-country areas it is not possible to predict avalanches because the forecast relies on the experience of the person making the observation. There are no computer models available to predict avalanches and therefore prediction is only accomplished by repetitive observations and knowledge of snow properties.
Due to difficulty in reliable prediction methods areas of avalanche hazards must rely on controlling or altering the effects of the avalanches.
The back-country explorer must be highly skilled in determining safe routes and rescue procedures over and above relying on prediction of avalanches for personal safety.
