Avalanche Summary

There was a natural avalanche cycle on Sunday. On Monday and Tuesday no activity was reported, although there are not many observers out there right now. Small wind slabs are the most likely type of avalanche during over the next few days.

Snowpack Summary

Approximately 20-30 cm new snow now sits on top of a rain crust that formed during the recent wet weather. The crust is reported to be thick (15 cm) below treeline and thin (2 cm) in the alpine. Strong winds have blown snow around in exposed areas creating drifts and scoured areas. Treeline snow depths are approximately 90 cm throughout the region.
