    Strong winds earlier in the week formed wind slabs at higher elevations. Riders are most likely to trigger them on steep lee slopes adjacent to ridges.

Avalanche Summary

We have not had any reports of avalanche activity. However, riders could still trigger an avalanche, 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 can be found at alpine elevations, while the snowpack depth drops rapidly at lower elevations.

The snowpack is generally consolidated and bonding well, though hard wind slabs may persist on the surface at higher elevations.

Various melt-freeze crusts are found in the bottom half of the snowpack but are not avalanche concerns.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Be cautious of buried obstacles, especially below treeline.
