We looked at many different aspects between Snake Creek Pass, Pioneer and Sunset peaks and mostly found LS issues on slope angles over 40deg. Isolated pockets of SS also existed along ridges and exposed terrain features failing just above the new/old interface at lower density snow and graupel. All of these issues were mostly benign and manageable. The slide below also happened in steep terrain below a cliff band and was easily visually identifiable from a distance. I initially thought that the weak layer would be graupel pooling but after closer inspection I found 1-2mm facets that comprised the old snow surface with a small amount of graupel on top. Its likely that these facets formed from diurnal recrystallization over the last week of clear skies and I suspect they can be found in other upper elevation shady, sheltered terrain.

I think that most of the usual storm snow instabilities will settle out quickly but this specific NSF problem may linger a while. Again, this problem was mostly benign due to the shallow nature of the slab on top of it but it could catch people off guard as we start to get complacent after the storm.
