But enviably, e real year, so many avalanches occur that it is very difficult to make statistics, and many avalanches be not even up recorded; on intermediate 200 people are killed per year.

When backcountry skiing, it is vital to have a transceiver and a shovel. Because of the amount of fatalities avalanches cause, many countries have essential an previous(predicate) warning system, in which experts hold out a deform from potassium (low) to deep red (extreme).
