Avalanche Summary
No new avalanches were reported before 4pm on Saturday.
If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.
Snowpack Summary
With the recent cooling temperatures, we expect the past new storm snow to have effectively bonded to the old surfaces. Anticipate past wind to have stripped south and west-facing ridges down to frozen crusts, while deeper and potentially more reactive slabs have formed on north and east-facing slopes.
Below treeline, you'll likely find dirt, shallow, heavy, moist or wet snow.
The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.
Overall, the snow depth remains shallow, creating challenging travel conditions and hiding early season hazards just below the snow surface.
