- <p>Heavy recent snowfall and density changes within the storm slab from multiple pulses since Saturday were main concern. One interesting full depth ECT result on a Northerly aspect. Along the North/South pieces of the ridgeline crossloading was evident from the NNW winds of the last 24 hrs. Some northerly aspects had the storm slab more compacted and the surface stripped, these areas I found isolated cracking along ridge. Surprisingly little avalanche activity however, saw only loose new snow that had moved during the higher PI periods.</p>

- <p>In ECTs on N and NE aspects around 9700 ft, the storm slab showed multiple subtle density changes and progressive compression failures at these interfaces (under the 11 to 14 cm received overnight and 34 to 36 cm down from the previous day's accumulation). Pits were dug 25 ft. off the ridge in Jupiter and Scott's Bowls, both had ~85cm depth. Storm slab had overall decent structure though and I imagine will remain cohesive if we can avoid prolonged high pressure.</p> <p>One due North aspect pit in a more exposed area down from the ridge showed developed 2 mm facets for the first 4cm off the ground. This produced an ECTP25, Q1 SP on this layer. While I think that these isolated basal facet layers are thin enough to be broken up by terrain and rocks, logs, other natural features, it seems like the right triggering circumstance could produce one of these full depth slides and the nice storm snow we just got could become a much uglier slab scenario.</p>
10 to 15 cm of new light density snow on top of yesterday's. The top 35 cm showed multiple layers and interfaces
