Avalanche Summary
No new avalanches were reported over the last few days in the region. If you are out in the mountains please consider filling out a Mountain Information Network report.
Snowpack Summary
Wind direction has varied over the last couple days. Wind slab could be found on all aspects as a result. These new wind slabs will have formed over old hard slab and facets meaning they likely won't bond well. East facing slopes will likely still have signs of scouring.
The December 15 surface hoar layer is 10 to 20cm below the surface in sheltered treeline and below . It is likely not a problem yet
.Â
Snowpack depth at treeline typically ranges from 120-220 cm, with higher values in the western part of the region and tapering to the east.Â
Terrain and Travel
- Carefully evaluate steep lines for wind slabs.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
