重要な層と弱層とテスト結果
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.
