Storm slabs may still be rider-triggered in areas without a surface crust. Deeper and more dangerous deposits will be found in areas lee to the wind.
As you move above the rain crust, investigate the bond of the recent snow to the layers below.

We haven't received any reports of recent avalanche activity.
Please consider posting a MIN if you head into the backcountry.
A rain crust may have formed over around 40 cm of storm snow from earlier this week.
A layer of surface hoar and/or faceted grains and a hard melt-freeze crust from mid-November sit in the middle of the snowpack. Weak faceted grains may extend to the base of the snowpack, particularly in areas where the snowpack is thin.
Snow depths at treeline vary from about 50 to 100 cm and decrease rapidly at lower elevations.
