Quick report

Found a variety of wind affected surfaces with wind slabs unreactive to triggers.  Observed an old hard slab avalanche that released around 4500' from a cross-loaded slope on the East side of the valley deposited significant debris that crossed all of Gully 1, but did not run down the gully.  Winds were moderate to strong along the entire route and flagging was active along upper elevations ridge lines at the top of the valley.  

No signs of instability

Snowpack

12/1 raincrust crust was mostly intact in this location, with the snowpack faceting beneath.  Continued cold weather is causing the snowpack to facet (lose strength) with some form of sharp edges on the outside of grains throughout the snowpack.  Faceting overall is not yet significant in this location.

Stability tests produced no significant results (see full profile for more detail)
