Avalanche Summary
Numerous naturally triggered wet loose avalanches up to size 1.5 were reported on sunny aspects on Friday. A rider triggered size 1 wind slab was also reported on a steep west aspect in the alpine.
If you go into the backcountry, please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
Recent north wind has reverse-loaded some slopes. Wind slabs may be found on all aspects in specific locations below alpine ridgetops.
Strong solar radiation has formed a surface crust on sunny aspects. 20 to 30 cm of recent snow (above 1600 m) overlies a crust everywhere except north facing alpine slopes where the recent snow sits on older dry snow.
The facet/crust layer that produced large avalanches during early March is down 150-250 cm. It is currently considered to be dormant in most locations.
Many areas below treeline are either snow free or have very thin snow coverage. Expect difficult travel at lower elevations.

Terrain and Travel Advice
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Carefully evaluate steep lines for wind slabs.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
