Travel and Terrain Advice
Those who raise the elevation should pay attention to the formation of wind slabs. A strong westerly wind is blowing in the sky, so be sure to see where the wind wraps along the terrain and cross loading snow. If you see signs of the formation of new slabs on the snow surface, try to avoid convex or isolated terrain, which is an easy place to provoke. On the other hand, be wary of glide cracks at low elevations. It is often formed in places that cannot be seen from the top of the slope. The weather clearly tends to deteriorate, so make an action plan that takes that into account.
