Avalanche Summary

No avalanches reported.

Snowpack Summary

Alpine snow depths in the region are around 60 cm. 10-20 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

Wind Slabs

Only the highest slopes have sufficient snow for avalanches to be a problem. On these slopes, watch 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: North, North East, East.

Elevations: Alpine.
