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.
