Avalanche Summary
Most recent avalanche activity (mid to late last week) was limited to a few wind slab avalanches (size 1-2) triggered with explosives.
Snowpack Summary
Strong winds redistributed 15-20 cm of recent fresh snow and have formed wind slabs on lee features in the alpine around treeline. Weak snow can be found 30-80 cm deep around crust layers that formed in November and October. These persistent weak layers produced large avalanches last weekend but have gained strength since then. Snowpack depths range between 50-150 cm at higher elevations and taper rapidly below treeline.
