Avalanche Summary
We haven't received any recent reports of avalanche activity. Looking forward, it may be possible for riders to trigger slabs, particularly in wind-loaded terrain features at treeline and alpine elevations.
Watch out for early-season hazards like creeks, logs, and rocks, particularly at lower elevations.
Please consider sharing any observations you have on the Mountain Information Network.
Snowpack Summary
Around 100 cm of snow is found in the alpine, with the snowpack depth rapidly dropping with elevation below treeline. Recent snow and strong wind have formed storm and wind slabs, which are likely starting to bond to the snowpack. New snow and wind on Friday may form new slabs, particularly in wind-exposed terrain at high elevations.
Various melt-freeze crusts are found in the bottom half of the snowpack but are not avalanche concerns.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
