Points saillants

There has not been enough spring like weather to create a strong spring snowpack that is typical for this time of year. Decision making and travel should be based on the fact that it is still a late winter snowpack.

    Fresh wind slabs may be found in the alpine. Be extra careful in the immediate lees of alpine ridges, and on steep convex rolls.

    On solar aspects the recent storm snow is sitting on several well developed sun-crusts. These sun crust may provide a good sliding interface. Be careful on solar aspects especially in the afternoon when these slopes warm up.

  • Deep Persistent Slabs

    The Feb 12 surface hoar is still surprising us a with isolated large avalanches that are being triggered by skiers. The terrain of most concern are weak, shallow and rocky snowpack areas. In deeper snowpack areas this layer is not as reactive.
