雪崩などの観察 Avalanche Observations Sc LW 10cm deep up to size 1 on uncompacted E aspect, slow moving debris. No tests in steep solar aspects due to poor travel conditions. Some blockfall observed on steep solar aspect in backcountry, remnants of previous glide slab avalanche.

積雪構造 Snowpack Above freezing temperatures and rain mean previous HN (10cm) continues to be wet on all aspects and elevations, reactive to ski cuts. The rest of the pack is wet and weak but is not reactive to ski cuts. Ski penetration over 20cm in most places, 10cm and supportive only on N aspects above 850m. Notable glide cracks growth at all elevations.
