Deep snow skiing

Downhill runs

Open, yellow-marked runs are ideal for avalanche-safe deep-snow skiing. They are secured by the piste patrol against alpine hazards (e.g. avalanches), but are not groomed and only prepared and checked to a limited extent (no final check). On yellow runs, hazards such as rocks, tree stumps, hollows, etc. are to be expected.

Open terrain

Open terrain away from snowsports facilities is neither marked nor secured against alpine hazards such as avalanches. This applies in particular to so-called “wild slopes” (shortcuts or links between two runs) and freeride runs.

Assessing avalanche risk is difficult. If you want to leave the secured pistes and runs, take an avalanche course or join a group led by an experienced guide.

Before setting off, get up-to-date information on the weather conditions and terrain. This includes consulting the latest avalanche bulletin (slf.ch, “White Risk” app) and choosing a route with a low avalanche risk. Freeriders must always carry the necessary emergency equipment (avalanche transceiver, probe, shovel). It is important to practise using the emergency equipment and familiarise yourself with the avalanche rescue procedure. An avalanche airbag provides additional protection.

Risk factors

The risk of triggering an avalanche depends on the prevailing conditions, the terrain and the behaviour of everyone involved. Avalanches can be triggered from a gradient of around 30°. The steeper the slope, the higher the avalanche risk. Over 90 % of avalanches are triggered by skiers and snowboarders themselves. A cautious approach is crucial to reducing the risk of an avalanche. Even small avalanches can have fatal consequences, so make sure you avoid the risk of getting caught in an avalanche at all costs.
