Avalanche Summary

No new avalanches have been reported since Wednesday.

Snowpack Summary

Treeline snow depths are typically 50 to 80 cm, with deeper wind-loaded pockets in the alpine. Heavily wind-affected surfaces are being reported in exposed terrain. A new sun crust is reported to be forming on steep, sun-exposed slopes.

There is a melt-freeze crust near the base of the snowpack, but it generally appears to be stable and is not currently expected to be a problem for the region.
