Avalanche Summary

No new observed today

Snowpack Summary

Teams travelled in to the alpine today up to 2500M. No wind effect noted in our travels, however variable winds were constant today and fresh transport was observed in the alpine and off ridges.

The Dec 1st crust is down roughly 60cm and is starting to slowly facet out. No notable results as of yet, but continue to watch this layer morph and change as the season progresses.                          

Terrain and Travel

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
