Snow cover is still minimal. Small isolated wind slabs at the top of lee slopes in the alpine remain to be monitored. Getting out on the mountain? We need your observations! https://www.avalanche.ca/mountain-information-network

Avalanche Summary
No new avalanche activity has been observed or reported. Please share your observations at info@avalanchequebec.ca, or with the Mountain Information Network.
Snowpack Summary
Between 15 and 30 cm of snow covers the widespread December 8 melt-freeze crust. Strong to extreme northeasterly winds have redistributed the new snow, exposing facing slopes to rock or crust and accumulating up to 100 cm in sheltered leeward areas. Surface wind slabs are fairly firm in the alpine and much softer at treeline. Despite the influx of new snow, snow conditions remain minimal. The crust and obstacles such as rocks, stumps, trees and trunks are barely covered and just waiting for you to leave beautiful marks on your skis or board, or to catch your shins.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Problems
Wind Slabs
Isolated wind slabs exist at the top of southwestern slopes in the alpine. In places, they cover a melt-freeze crust above which facetted grains are developing. This combination constitutes an avalanche-prone sliding plane.
Aspects: South, South West, West.
