Avalanche Summary

A few new loose dry avalanches but overall no new slab activity was observed.

Snowpack Summary

Isolated windslabs can be found in alpine terrain along ridgelines and in cross loaded feature but the overall lack of wind has been suprising!  These slabs are on all aspects also due to the recent northerly flow.  The upper snowpack continues to facet and in thinner areas, the entire snowpack is facetting.  Generally the midpack is supportive and bridging the weaker basal facets but dont forget this weak base.  Depth hoar and large facets dominate the base of the snowpack and large triggers such as a cornice, or avalanche in the upper snowpack could wake up this weakness.  Thin areas are also likely places where one could trigger the basal facets so be thinking about thick to thin terrain....
