    Thin areas should are where you could wake up the basal layers. Large and steep Alpine features are still a concern.

Avalanche Summary

No avalanche activity observed or reported today.

Snowpack Summary

Pretty widespread wind slabs in the alpine from the hard drummy type to pockets of soft slab.  The snowpack is continuing to facet with the continued cold temperatures. We have a pretty strong mid to upper snowpack that is bridging  the basal facets that make up the bottom 50cm of the snow pack.  Though a full-depth avalanche is unlikely, if it does occur it will be catastrophic. Large triggers, such as a cornice failure, or triggering from a shallow snowpack area, are possible ways to wake up the deep persistent weak layer.
