Old snow
Avalanche prone locations
In all aspects above approximately 1800m.
Danger description
The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack. Even single winter sport participants can release avalanches easily. Avalanches can be triggered in the old snowpack and reach large size. Remotely triggered avalanches are possible. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.
Backcountry touring and other off-piste activities call for extensive experience and restraint.
Gliding avalanches
On very steep grassy slopes gliding avalanches are possible at intermediate altitudes.
