Travel and Terrain Advice
Beware of unstable slabs that remain in certain terrain. Convex, extreme shapes, or wind slabs resting on very steep slopes should still be sufficiently inductive. If there are no traps in the terrain and the slope is not affected by the wind, it is possible to safely glide in fresh snow with support. Even if you feel that snow cover is trending steadily, you should continue with the principle of action, such as stopping in a safe place and moving at reasonable intervals in places exposed to avalanches. Habitalizing such a good behavior will reduce accidents in case of an emergency.
