Avalanche Summary

We haven't received any reports of recent avalanches. Looking forward, riders could trigger newly formed wind slabs in wind-loaded alpine terrain.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

The alpine has received 50 cm of snow over the past week, which settled quickly. Strong southwest wind is redistributing the snow, loading cross-loaded and lee terrain features in the alpine. Wind-hardened surfaces are expected on southerly slopes. Wind-sheltered terrain may still have soft surfaces.

Cornices are large and looming at this time of year.

Terrain and Travel Advice

The best and safest riding will be on slopes that have soft snow without any slab properties.
Pay attention to cornices and give them a wide berth when traveling on or below ridges.
