In the small window of weather, we were able to visually confirm multiple crowns in prime time avalanche terrain. That observation was pretty impactful as there isn't a lot of avalanche terrain in this location, which is why we chose to travel here. On the drive home, there were many naturals in small, obscure pockets of forest. There is no question that is has been naturally avalanching over the last 12hours.
Cold front seemed to past through around 1100hrs with some wind and S2-3. There was a lull mid day, followed by more S2-3 on exit at 1600hrs.

Numerous pockets of Soft Slabs along the Big Wood River (near Frostbite Flats) and on the N-NE slopes of Oregon Gulch facing the Big Wood River.
If the numerous collapses weren't enough info, Ben had an ECT fail on isolation down 70cm. We did notice a supportable crust on a SE slope with a thin layer of facets on it. All E-N terrain had a healthy layer of 1-2mm FC that were F hard.
Layer Depth/Date: 60-70cm/1127
Weak Layer(s): Nov 27, 2022 (FC)
Comments: Many collapses on this layer on multiple aspects. We anticipate this layer at upper elevations as well (not directly observed).
We methodically choose an area that had amble simple terrain to avoid the avalanche hazard for the day. We entered the field with an Assessment mindset and were looking to gain information on how the slab was consolidating and bonding with the underlying weak layer.
