Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
Wind affected snow can be found at higher elevations, with recent storm totals of 10-20 cm sitting over a crust below 2000 m.
The snowpack below is considered settled. Weaker layers exist but with thick crusts sitting above, triggering avalanches on these layers is unlikely.
Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m.
