Avalanche Summary

In the past few days, avalanche observations have been limited to a few small (size 1) dry loose avalanches from steep terrain.

Observations are very limited at this time of year! If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

Snowpack Summary

Up to 30 cm of recent storm snow has been redistributed by moderate variable winds at treeline and above.

A crust buried in early November is 50-90 cm below the surface. In some places, there may be weak facets or surface hoar above this crust, but the geographical extent of this weak layer is still uncertain.

Treeline snowpack depths average 80-150 cm.
