Snow drifts, old snow
Avalanche prone locations
In all aspects above approximately 2400m.
Fresh snow drift accumulations are to be found in particular adjacent to the ridge line and in gullies and bowls. They are in some cases prone to triggering. Careful route selection is advisable.
North facing slopes above approximately 2500 m: Avalanches can be triggered in the old snowpack and reach medium size in isolated cases. This applies in particular in Valais. These avalanche prone locations are difficult to recognise. Caution is to be exercised at transitions into gullies and bowls.
