Avalanches are one of those natural occurrences that only Mother Nature knows when and where theyre going to occur. Even with modern technology its still impossible to know exactly when or where one is going to occur. For mountain climbers this is a major concern and they are wise to be mindful of them; avalanches kill many each year.
The physics of how and why an avalanche occurs is complex. Layers of rock and feet of snow are stacked and held together by the weight of each other. Many variables can lead to the adjustment of this bond and the forces of gravity can lead to the catastrophe.
While its hard to predict when and where an avalanche will take place, there are times of higher probability. During the year, the transition from winter to spring will cause some snow and ice to melt which tends to trigger avalanches. Also at day break there is a higher probability due to the temperature change. Unfortunately there is no way to know when or where one is going to occur so climbers always need to exercise caution.
Stay alert while climbing and dont overburden yourself with the thought of an avalanche. This worrying may cause you to loose your concentration...
