Low danger does not mean no risks. Watch for the development of wind slabs throughout the day and before committing to a more challenging line.
With this layer of ice barely buried, carefully assess the consequences of a slide on it.

Snowpack Summary
Moderate to strong northerly winds have redistributed the 5 to 10 cm of snow overlying the January 18 ice crust, which varies in thickness and stiffness. That crust is much more friable (and skiable) in areas with a denser canopy. Be careful, though, if your skis go below the crust, the thickness and stiffness of it could cause injury. In the alpine and at treeline, these winds have exposed this icy surface in many places.
It goes without saying that travelling in the alpine and on steep terrain is still adventurous. Many obstacles are still not covered, increasing the consequences of a slide on the ice. In the alpine, snow surface go from exposed rocks, to ice, to areas of greater accumulation. In general, the heights of the snowpack vary from 50 to 100 cm depending on the sector and the altitude.

Terrain and Travel Advice
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
Problems
Wind Slabs
Accumulations from snow transport may not bond well to the very icy crust.
