Avalanche Summary
Our field team observed rider triggerable wind slabs in the north of the region at Pine Pass. Check out the MIN.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Check out this MIN from our field team.
Up to 30 cm of new snow with southerly winds has formed wind slabs on lee features at upper elevations. This new snow sits over a crust up to 1400 m on all aspects. Surface hoar may be found under this new snow in shelterd areas.
Two additional layers of surface hoar can be found in the top meter of the snowpack at treeline. These layers are generally no longer a concern, the exception being shallow rocky areas at upper treeline.
The current snowpack has considerable variation in structure and depths across the region and is shallow for this time of year.
