Avalanche Summary

Snowpack Summary

Sun/temperature crusts exist on all aspects to 2300 m, and to ridge tops on solar aspects. These crusts will break down with afternoon heating. Shady aspects hold dry, settled snow above 2300 m. The January 24 persistent weak layer (facets over crust) is down 70–160+ cm and has been unreactive this week. Below this, the snowpack is generally strong with no significant weaknesses.
