Glacier.

Watch out for sluffing in steep terrain with 7cm of new snow overtop a smooth gliding surface like a sun crust. Be aware of terrain traps below you.

Summary

Problems

Deep Persistent Slabs

The February weak layer is buried down 1.5 to 2 m. Although infrequent, this layer has been reacting to skier triggering particularly at treeline elevations. Consequences are high if this layer does fail.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely

Expected Size

1 - 3

Cornices

Most ridges throughout the Park have massive cornices. Cornice failure is unpredictable. Be aware of the overhead hazard on your approach. They are large triggers and could produce avalanches on the deeper instabilities.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

2 - 4
