No recent avalanches observed.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!

Snowpack Summary

Alpine snow depths in the region are around 60 to 80 cm. 10 to 30 cm of recent storm snow overlies a layer of surface hoar that was buried on November 21. This layer is expected to be variable in nature and may have been melted into a crust on southern aspects.

Problems

Storm Slabs

Only the highest slopes with relatively smooth ground surfaces have sufficient snow for avalanches to be a problem. Keep your eyes open for pockets of wind-blown snow.

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.

Aspects: All aspects.

Elevations: Alpine.
