Kernpunkte

The deep persistent instability appears to be dormant in the snowpack; however, remain vigilant and make conservative decisions being its still only November. Early season hazards exist with variable snow-depths.

    The windslab is present on NE to S aspect lee features. Westerly aspects are stripped bare from previous transport.

    Assume all skiable slopes have this layer, and assess the strength of the interface before jumping into a committing lines. Depth is variable depending on aspect and elevation.

Snowpack Summary

Winds have scoured W ridges to rock making E aspects more prone for windslabs but may be found on NE through S, lee aspects. The Oct 25 crust is 2-4cm thick and down 60 to 80cm. Hard progressive collapse failures observed immediately below this crust on in test profiles, Sunday. Early season hazards are very present.

Avalanche Summary

On Saturday, several dry loose activity up to size 2 observed from steeper alpine rocky solar terrain likely triggered by sun. Sunday no new avalanches observed and visibility was good.
