Snowpack Summary
Above 1700m 5-15cm of light snow sits on the Feb 14 crust, which is supportive to ~1900m. The Jan 30 crust layer is down ~1-1.25m is becoming more stubborn to trigger. Jan 15 surface hoar down ~1-1.5m gives sudden test results in isolated areas. The mid and lower snowpack is well settled. Nov 9 basal crust layer still present in the alpine.
Avalanche Summary
Solar triggered avalanches have been observed for the past 2 days to size 2.5. On the weekend, impressive deep slab avalanches occurred. A size 3.5 from the col between Clarke Peak and Mt Swanzy was likely triggered by cornice fall and ran on glacier ice. In the Asulkan Valley, a size 3.0 from Mt Pollux ran on the Nov 9 crust/to ground.
