Avalanche Summary

No new avalanches observed. Very limited observations.

Snowpack Summary

Up to 5cm of snow has fallen on Wednesday. The most interesting part was that the top 30cm of the snowpack felt like a soft slab and was widespread from tree line and above. This might of been caused by the recent winds or the warmer temperatures Tuesday night and Wednesday during the day. Either way, it felt slabby and we pulled back from steeper terrain. There are still a couple of buried wind slabs, the November crust and October facets near the base to think about.
