Avalanche Summary

No new avalanches observed on Tuesday.Please submit your observations to the Mountain Information Network.

Snowpack Summary

A variety of snow surfaces exist throughout the region. Stiff wind slabs sit on a wide range of aspects on alpine and exposed treeline slopes. In sheltered treeline and below treeline terrain, I suspect light amounts of low-density snow intermingle with surface hoar and surface facets (sugary snow).Roughly 30-60 cm below the surface you'll likely find a hard crust that was buried near the end of November. This crust is approximately 30 cm thick and extends from 1600 m to mountain top on all aspects. Below this crust, the snowpack is moist to ground. Average snowpack depths at treeline elevations in the region range from 80-120 cm.
