Avalanche Summary

No new avalanches have been reported in the last 3 days.

Please submit a MIN report if you have travelled in the backcountry recently.

Snowpack Summary

Surface conditions include sun crusts on south facing slopes, wind-affected snow in exposed areas at higher elevations, and small amounts of settling snow in sheltered terrain.

A widespread crust is buried 40-90 cm deep, in some areas a weak layer of facets can be found above. However recent tests suggest this layer is gaining strength and avalanche activity is unlikely. No recent avalanche activity has been reported on this layer in this region.

The snowpack below this crust is strong and well bonded.
