In sintesi

Until we get more snow, ski conditions will remain challenging. On the upside, avalanche hazard is improving with each day.

    Facetting is helping ease this problem at treeline. The alpine on the other hand is still covered in windslabs of varying densities.
  • Deep Persistent Slabs

    Large triggers are a concern. It's safe to say we're in the "low probability/high consequence" situation.

Snowpack Summary

Below treeline has really felt the cold. Any area that was loose snow prior to the cold is now weak and facetted. This isn't a bad thing, many windslabs have lost their cohesiveness thanks to that cold snap. At treeline the wind slabs are immediately noticeable once exposed terrain is reached. For the most part these slabs are thin and sometimes breakable. Steep, unsupported terrain may have reactive windslabs lurking, but for the most part the slabs are well bonded to underlying layers. The alpine. Judging from today's trip, it takes a brave soul to do battle with the current windslabs. They are widespread and either breakable or eerily hollow under foot. These feel as though they could be triggered from shallow, transitional areas.
