Continued cracking, collapsing, and remote triggering are clear indicators that avalanche hazard will not be decreasing quickly. Snowpack is complex, with several different surface hoar layers, crusts with facets, and depth hoar near the ground. Additional loading will reactivate this problem easily.
Occasional S-1 flurries through the day with no significant accumulation. 2cm overnight based on sled tracks from yesterday. Wet north wind blowing steady moderate in upper elevations, transporting small amounts of snow.

|D2.5||SS||O-Old Snow||N-Natural||NE-SE aspects, several different crowns visible, based on depth most seemed to be activating 12/7 interface, but some deeper portions may have been picking off weak snow at 11/26. These layers are pretty close together in the Sawtooths, so it may just be heavy wind loading that was causing differing crown depths. Low certainty.||None|

|S-SE aspect. Triggered from ridgeline above, 100-150m away along slope. Failed on top of MFcr with facets. I was able to find some SH grains here as well, but not enough to convince myself that it was a primary culprit. Slab was wind stiffened, approaching 1F+ hardness in places||None|
Surprising lack of natural activity in the Smokys, particularly given how touchy the snowpack appears to be. I could find a few smaller piles of mid-storm debris below obvious paths (D2 estimated based on debris) but less than I expected. Sawtooths look like they put on a show, based on brief glassing from highway. Would be interested in looking at crowns and seeing what the culprit in the upper pack was. I found plenty of SH buried at 12/7 interface when I was there 12/10, and plenty of (then) unburried
Layer Depth/Date: 12/7 down 40-60cm
Comments: SH and FCsf buried on 12/7. With our without a crust, depending on aspect.
Avoided avalanche terrain that had not already avalanched. Avoided runouts below avalanche paths that could be triggered remotely.
