Avalanche Summary

No new avalanches were reported in this region on Thursday.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Predominantly wind affected snow surfaces are found in the alpine. Wind-sheltered terrain may hold settled soft snow that can produce dry loose avalanches with skier traffic in steep terrain. Steep sun-exposed slopes will moisten with daytime warming and freeze into a hard melt-freeze crust overnight.

Cornices are large and looming at this time of year.
