Stability: poor · Frequency: few
Weak layers in the lower part of the snowpack represent the main danger.
Weak layers in the old snowpack can be released especially by large additional loads in particular on steep shady slopes. This applies in particular in little used terrain, as well as in areas where the snow cover is rather shallow above the tree line. In steep terrain there is a danger of falling on the hard crust.
The old snowpack will be subject to considerable local variations in some places. Towards its base, the snowpack is faceted and weak.
