Points saillants

With only 15cm of new snow at treeline through the recent "storm", there has been very little improvement in the ski quality. Any avalanche triggered will likely involve the entire season's snowpack, so choose lines conservatively.

    Reverse wind-loading has formed thin wind slabs on W through SE aspects. In some cases these slabs sit on layers of sun crust or surface hoar. The likelihood of triggering is highly variable, so use caution when choosing terrain features.
