Problem #1 Comments
Poor structure and basal facets still exists and was found on NW-N-NE-E facing slopes, however we could not get propagation in our extended column tests. Sudden Collapses were noted in Compression and Deep tap tests with hard taps. These facets were damp or frozen and showing some signs they are continuing to strengthen. Many tracks center punched No Name with no releases. Bowl looked somewhat crossloaded with soft windslab on east facing portion of terrain feature. This is the same terrain that avalanched huge during the Thanksgiving cylce. Perhaps much of the weak snow cleaned out and it isn't likely to repeat, or there just hasn't been enough spatial sampling to find the sweet spot again?
We could not find a slope with enough south in it to locate the new Persistent Weak Layer of Facet/Crusts. The flurry of recent reports of avalanches on this newly buried layer is concerning and challenging to grasp considering these southerly slopes have been primetime, go-to terrain since Thanksgiving. The wedge of terrain devoid of any persistent weak layers has just gotten smaller. Where do we go from here is the question we should be asking ourselves. This is not an uncommon issue to see this time of year per se, as one cagey instructor related to me earlier. In fact, this very problem of Facet/Crust on Southerly slopes has been responsible for fatalities in recent memory. A new load of snow and wind on this layer is coming through the next 24-48 hours. This is not the time for complacency and we need to be head's up again as things get a bit more complex moving into January. As LaChapelle said-"Do nothing in haste, Look carefully to each step, and from the beginning, think what may be the end."

Problem #2 Comments
See above comments, but this appears to be a compounding issue to the newly buried PWL of Facet/Crusts. Wind direction has been variable since New Year's Day and all upper elevation aspects except due west are suspect for loading. Easily identifiable at this point by the unique textures and raised surfaces, these wind slabs may become buried and harder to spot with new snow through Sunday. The warm temps likely did quite a bit to stabilize this problem since January 3.
Comments
Travel was up through Colony terrain near base of Gondola and onto No Name Bowl North Ridge and run out of No Name Bowl. Did not enter avalanche terrain today. Temps were mild at the trailhead and winds were well behaved in the lower reaches. Evidence of some previous transport was noted. Cloud cover started overcast, broke up briefly mid afternoon, and then rolled back in as the winds picked up around 4pm. No precip today. Next storm looks promising.
