Weather Comments
Arrived at the trailhead around 11 AM with about an inch of new snow on the road and in the parking. Visibility was low, temperatures were cold, and moderate winds with occasional strong gusts from the west. Light snowfall with notable drifting snow. Not a super pleasant weather for a tour.

Snow Characteristics Comments
On solar aspects we were able to have a supportable crust from last week. Out of the solar zone, we were able to find weak faceted snow in protected areas and firm wind-textured and wind drifts up to 8" thick in isolated areas.

Supportable crust on a Southeast aspect.

Comments
Headed on a tour to get one final look at both the snow surfaces, and what was going on below the snow surface before this storm moved through the Western Uintas. While very little actual precipitation had accumulated by the time we got to the trailhead, winds were elevated and notable transporting a lot of snow. This made for a mixed bag of snow surfaces for the new snow to bond to. Even with such elevated winds, no instabilities other than subtle cracking on newly developed wind deposits.
On solar aspects, we were able to find a supportable crust 3-4" thick with chaining facets below the crust. The remainder of the snowpack to the ground was faceted snow. This could make solars a bit more complex moving forward, as it will support new and drifted snow longer than the areas without a crust, but below the supportable crust, the entire snowpack is faceted. So while it could change the timing, it will still react similarly to all other aspects possessing full-depth facets.
On a wind-protected Northerly, we were able to find the 3-4mm buried surface hoar from the past two weeks of generally dry weather fully intact. This buried surface hoar was resting atop 60cm of facets to the ground. We were able to get collapse, but no propagation on this layer. This represents areas that were protected from the wind, I would guess in the wind zone this buried surface hoar likely got knocked down.
