Travel and Terrain Advice
Pay attention to wind slabs due to yesterday's snowfall, which were deposited locally in Alpine. The snow surface is very hard and frozen due to rainfall, and it is always possible to climb seals, and crampons are needed. Usually, even if you have been training to stop slipping, it's actually hard to stop once you slip. Please choose more safe terrain and take careful action.
