More detailed information about the snowpack: 

I went for a tour this afternoon in the Sherwin’s to get a sense of how things were changing with the new snow.  No cracking, wumphing, or recent avalanches were noted on my tour.  I reached the ridgeline at around 3pm and noted significant transport occurring with the strong southwest winds.  At the time of my observation I was able to find small isolated pockets of wind slab developing on the leeward side of the ridgeline. These slabs were seemed quite fresh and while they were sitting on loose faceted grains the slab was not yet cohesive enough to see significant propagation.  Digging into one of my test slopes showed 4-6” of 4-finger wind slab on top of fist hard new snow/faceted grains. I also dug a couple quick pits in sheltered areas looking for buried surface hoar and was unable to find any.  At 10,000 ft after descending from the ridge I noted 6” of low-density new snow, 40 cm of ski pen, and intensifying showers.  While the new snow certainly cushioned things out a bit for my decent, I was still able to find some rocks to sharpen my edges on.
