Weak layers in the old snowpack represent the main danger. There is a danger of falling on the icy crust.
Distinct weak layers in the old snowpack necessitate defensive route selection. Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants in particular above approximately 1900 m. Avalanches can penetrate even deep layers. The avalanche prone locations are clearly recognisable to the trained eye.
The snowpack will be in most cases subject to considerable local variations. Towards its base, the snowpack is faceted and weak. This applies in particular on steep shady slopes above approximately 1900 m. In steep terrain there is a danger of falling on the icy crust.
