重要な層と弱層とテスト結果
積雪構造 Melt freeze cycle continued with strong MFcr on all aspects at all elevations in morning. This crust broke down during day everywhere but N aspects above 1000m. Upper 10 - 20cm became wet & 4f/F hardness on E & SE aspects. Upper snowpack firmer (P) and unreactive in all other areas.
Picture is Na LW Sz 1.5 at 1100m, outside current ski area boundary.
