Very weak snowpack was easily overloaded by this weekend's storm. Not expecting this problem to get better quickly. This is not the type of base I was hoping to build the snowpack on this year.
Variably cloudy, generally clearing through the day, but lots of scrappy clouds passing through with occasional S-1 showers. Quite a bit of solar input. 40cm snow from weekend's storm
Eagle Creek Headwall
|Remotely triggered three pockets, 30-50m wide. Trigger distance varied from 10m to 100m. Avalanches failed on 10-15cm layer of faceted snow left over from Thanksgiving storms|

||D1.5||SS||N-Natural||Various aspects and elevations, lots of evidence of D1-D2 activity during the storm. Difficult to tell exactly what the bed surface was, some appeared to be failing on a mid-storm density inversion, others at the new/old interface (12/7)|

Galena Pass Roadcuts
||Slides in 3 or 4 locations on Galena Pass. I was driving north and didn't have time to look at crowns directly. None seemed to be deeper than the new/old interface.|
Very thin layer of snow leftover from Thanksgiving storms was capable of producing remotely triggered avalanches. No snow in this area prior to Thanksgiving.
Layer Depth/Date: down 30-45cm, buried 12/7
Most sensitive on slopes without a significant sun crust (formed on due souths only)
