Avalanche Summary
There was a report of a size 1.5 wind slab avalanche at treeline on a north aspect in Manning Park on Saturday. Otherwise, no new avalanches have been reported in this region.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
10-20 cm of snow sits over a thick supportive crust below 2000 m. In wind-exposed features, winds have transported available snow into wind slabs.
Below this, the snowpack is considered settled. Weak layers exist within the mid and lower snowpack but the thick crusts sitting above them make triggering avalanches on these layers unlikely.
Snowpack depths are roughly 150 cm at treeline and taper rapidly below 1500 m.

Terrain and Travel Advice
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Be especially cautious as you transition into wind affected terrain.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
Problems
Wind Slabs
Use caution around ridge crests and wind-loaded features, variable winds are transporting snow and promoting wind slab development in exposed areas.
