    Hard slabs are widespread and present the only real problem in the snowpack. Although it seems unlikely, it could be possible to trigger an avalanche in a steep pocket with a hard slab. Mostly these slabs are bridging any weakness underneath.

Snowpack Summary

Most areas above treeline and in the alpine have been wind blasted. Hard slabs are widespread, and provide a strong bridge over any underlying weakness. Below treeline, the snowpack is facetted throughout but no slab overlies this weakness.

Avalanche Summary

No new avalanches were observed along Highway 93 and Maligne lake road.
