Enjoy the good skiing out there, but take some time to assess the chosen runs properly. Especially if searching for new lines.MM

Problems

Wind Slabs

A variety of slabs from previous wind events continue to be a concern. These vary in thickness and burial depth. Near ridgelines and crossloaded features are still the areas these slabs will be encountered.

Avoid lee and cross-loaded terrain near ridge crests.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 4

Deep Persistent Slabs

This layer is still a concern despite the lack of activity. Today's snow study trip found a generally deep snowpack, however shallow areas were still found in the alpine. Treat these variable areas with caution.

Avoid shallow snowpack areas where triggering is more likely.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

3 - 6
