Avalanche Activity

A precarious avalanche situation will be encountered over a wide area.

Avalanches can over a wide area be released easily. The avalanche prone locations are to be found in all aspects above the tree line. Such avalanche prone locations are covered with new snow and are therefore barely recognisable, even to the trained eye. In isolated cases avalanches can penetrate deep layers and reach large size. Caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as on wind-loaded slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Remotely triggered avalanches are possible. Experience and restraint are important.

Snowpack Structure

The old snowpack is faceted. Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack. The various wind slabs have bonded poorly with the old snowpack.

Tendency

Avalanches can as before be released, even by a single winter sport participant and reach large size in isolated cases.
