Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Wind slabs remain in the Alpine and exposed treeline areas but are stubborn to trigger.Cold temperatures have transformed most of the snowpack into weaker faceted snow with few if any distinct layers, with the exception of alpine terrain where hard wind slabs and wind pressed snow are found near the surface.In deep snowpack areas, you may find a slab sitting above a layer of facets and surface hoar that was buried in mid-January and is now 30-60 cm deep. The layer is most prominent in the Elk Valley between 1600 m and 1900 m, but no recent avalanche activity has been reported on this layer.

Problems

Wind Slabs

Wind slab pockets are most likely found immediately behind ridge crests and in more aggressive terrain and lines.
