The Swiss Federal Institute for snow and avalanche research on Weissfluhjoch near Davos at 8700 feet above sea level

Of all natural phenomena, avalanches are those which are most feared by people, for in this mountainous country they have a significance that must not be underestimated, having in the course of many years taken toll of numerous human lives and much property. It is not strange, therefore, that the authorities and the people themselves have been concerned about them at all times. However, until a few decades ago this concern was limited to avoiding damage. Actual prevention was either not considered at all, or was approached only with great hesitancy.Peer reviewed: NoNRC publication: Ye
