Glacier.

Cautious route selection is still required with a persistent weak layer buried a meter down in the snowpack.

Summary

Problems

Persistent Slabs

Buried surface hoar down around one meter has been reacting to skier triggers. The overlying slab is well settled and has large propagation potential, therefore bigger consequences. These layers are most sensitive at treeline and below.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Possible - Likely

Expected Size

1 - 3

Wind Slabs

Winds throughout this past week have varied from all directions. Be aware as you travel into wind affected areas, like nearing alpine ridge crests, where a wind loaded pocket may catch you by surprise.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Expected Size
