積雪構造 Snowpack Moderate sized hard cornice on E aspects stubborn to ski cutting in morning. Wind slab on same aspects unreactive and isolated to within 5m of ridgeline. Large cornice formation observed in backcountry on N & E aspects. Previous new snow became moist during day due to solar and warm temperatures. Surface 20cm wet on solar aspects at all elevations. Ski penetration up to 50cm, but only able to push out snowballs when ski cutting, not entraining.
