Avalanche Summary

A cornice fall triggered a size 1 slab on Friday. Otherwise, no new avalanches have been reported.

Snowpack Summary

Cornices may be large and fragile. In some locations, wind slabs may be found in alpine terrain. On high, shady slopes, low density dry snow overlies a crust. Sunny slopes are likely to follow a melt-freeze cycle over the next few days (soft and weak surface by day; with limited refreezing by night). Recently formed crusts at or near the snowpack surface are strong and supportive below about 2200 m. At higher elevations and on shady aspects, these crusts have less strength. The mid and lower snowpack are generally strong and well-consolidated. Below treeline, there is limited snow cover.
