New snow and strong southerly winds are building fresh wind slabs at higher elevations. Carefully evaluate each slope for wind slabs before committing.

The best riding will still be in the trees and in sheltered areas away from the wind.

Avalanche Summary

No recent avalanches have been reported, but observations are limited this time of year.

Thank you for the MIN reports! They are extremely helpful to us in the early season when snowpack information is limited. If you head into the backcountry please submit a MIN report!

Snowpack Summary

10 cm new snow and strong southerly ridge winds are building thin windslab at higher elevations. In isolated areas at treeline and below new snow is burying a layer of small surface hoar and facets. New snow overlies heavily wind-affected surfaces in all open areas at higher elevations.

A layer from mid-November is buried 50 to 70 cm down at the treeline. This layer consists of surface hoar and facets. Below the treeline and on south-facing slopes it is a crust. November 27th and 28th saw activity on this layer but has so far seemingly been unreactive under the current conditions.

Many early-season hazards exist below treeline such as rocks, stumps, and open creeks.
