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
Recent new snow and wind has likely formed fresh wind slabs at upper elevations. In sheltered areas 20-30 cm of snow from last weekend is gradually settling. 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 50-100 cm at higher elevations and taper rapidly below treeline.
