Avalanche Activity

Danger spots due to persistent weak layers (on shady slopes). Wet loose-snow avalanches in all expositions.

The avalanche danger is in general low. Nevertheless some danger spots exist. There medium-sized slab avalanches can be triggered by high additional loads. Especially in entries to steep shady gullies and bowls and slopes above 2.000 m. The amount of danger spots increases with altitude. Spontaneous wet-snow avalanches in all expositions are possible.

Snowpack Structure

der snowdrift deposits are placed on a weak snowbase in shady high areas. Apart of that the snowcover could mostly stabilize due to warming. The snow base itself is formed of faceted snow and realtively soft. The upper layer does not freeze during the nights and rain showers lead to destabilization. This can cause spontaneous avalanches.
