Weather Comments
Beautiful bluebird day, a few thin clouds rolled into the back of Mineral by the end of the day, otherwise clear skies. Winds were light through the entirety of our tour, but there were obvious signs of the recently elevated winds on the snow surface.

Snow Characteristics Comments
2-4" of new low-density snow sitting atop of the old snow surfaces. Near the ridgeline, there were more obvious signs of wind, such as pillow-shaped snow and a scalloped surface. We ended our tour around 2P, but the snow surface on any sunlit aspects were beginning to become damp.

Comments
Headed up the lower east-facing ridge in Mineral Fork to look at mid-elevation North and east-facing terrain. It appeared that most of Mineral Fork got between 2-4" of new snow, a bit more had settled in areas that allowed for drifting. While winds were overall calm during our entire tour, it was obvious, by the snow surface, that they had been elevated overnight and into the morning. Once we got above treeline, there were obvious wind drifts and the cornice on the ridgeline had grown significantly since I was last in Mineral. Even with the obvious signs of wind drifted snow, we did not see any cracking or hear any collapsing while traveling on wind-loaded slopes.
We stuck our shovels right below the ridgeline on a NE aspect around 8800', the poor snowpack structure hasn't gone anywhere. We found a snow depth of 103, with approx 40cm of new snow and crusts atop 60cm of facets. While the faceted layer was still very obvious, we were unable to get propagation within our pit. We did get a collapse on the facets on the 21st tap - but it only collapsed beneath the shovel blade. I think this continues to show, that while the likelihood is decreasing, the consequences are still very high if you were to find that spot that propagated.
