    A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.

Moderate

Avalanche Summary

Several explosives triggered Deep Persistent Slabs, up to size 2, were reported by the ski hill on Wednesday. A good reminder that this problem is not going away, and triggering full depth avalanches is still a possibility.

Snowpack Summary

Up to 10cm of new snow has fallen with generally very light winds.

The snowpack is mostly made up of facets and ranges in depth from 60 to 120 cm at treeline and above. At the bottom of the snowpack there are multiple early season crusts with facets above and below.
