Snowpack Summary

Westerly winds continue, creating windslabs on lee locations in the alpine and open treeline. A buried layer of surface hoar lies approximately 20 cm below the snow surface. Reports indicate this layer was blown around before it was buried and can only be found in isolated, sheltered locations at and below treeline. A well settled mid pack bridges over the basal weaknesses at the ground.
