Snowpack Summary
Rain crust to 2100m. Above 2100m the upper snowpack is settling snow that is facetting with the cold temperatures. Surface hoar growing at this time to 6mm or more. Well settled mid-pack with 30cm crust/facet basal weakness (Nov 9) observed in certain locations.

No new avalanches were observed yesterday.
Confidence
The weather pattern is stable
Problems
Persistent Slabs
Weakness at the bottom of the snowpack in some areas throughout the Park from the November crust. Thin snowpack areas on a large alpine slopes are most suspect to release this layer. It is difficult to trigger but will have large consequences.
Avoid shallow snowpack areas where triggering is more likely.
