Avalanche Summary

No avalanches have been reported in the region yet this season. Please consider filling out a MIN report if you are out in the backcountry.

Snowpack Summary

10-20 cm of storm snow has buried the variety of surfaces currently covering the mountains. A buried crust likely exists on all but high north terrain. In sheltered features surface hoar can be found above this crust. The recent snow may not be enough to overload the surface hoar, but deeper, windloaded features at treeline may be more reactive that you expect.

Snow depths throughout the region range from about 30 to 60 cm at treeline, increasing with elevation. Some wind loaded spots may hold up to 90 cm.
