    Recently formed wind slabs may still be reactive to rider traffic. Be cautious when seeking out protected terrain on east aspects, as a layer of buried surface hoar may still exist.

Avalanche Summary

There was a report of a size 2 storm or wind slab avalanche off of Fraser Peak on Saturday. See this MIN post for more details.

If you head into the backcountry please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

20 to 30 cm of new snow fell last week. This has been redistributed by primarily southwest wind.

The mid and lower snowpack is reported to be well settled, with a thick, well-bonded crust approximately 30 to 50 cm above the ground at elevations below 1200 m. Snow depth ranges from 80 to 200 cm across the region.

Of note, a layer of surface hoar was found in the Halcyon Fraser Chutes area on Dec 28 and 29. check out these MIN reports here and here for more details.

Terrain and Travel Advice

  • Approach steep open slopes at and below treeline cautiously, buried surface hoar may exist.
