More detailed information about the snowpack: 

Hiked up Shed 7 East to check on weather station and inspect early winter condtions at upper elevations.  Found 0-50cm of snow on most aspects and slopes above 5000'. 

We experienced light - moderate SW winds all day with temperatures below freezing and constant.  In specific isolated terrain, we experienced small shooting cracks.

We dug a quick pit in an isolated windloaded NE slope near the weather station (at 6000') to take a peak at the halloween crust, the thanksgiving crust, and any recent snow accumulation over the past week. The Thanksgiving rain event appears to have drenched the entire underlying snowpack, including the halloween crust. The Thanksgiving crust was 20cm thick, about 50cm from the surface, and challenging to dig through. Above it, we found a mixed layering of new fallen and wind drifted snow with a reactive 5cm thick weaker layer of new snow lingering ~30cm from the surface. There was a noticable windslab forming on the surface of the snow. Test result: ECTP12@80cm on the mentioned soft layer.
