Quick report
- Collapsing
- isolated
The few whumph on the valley floor gave us some caution and dictated much of our terrain decisions. We therefore traveled mostly on prevous slid terrain. Everything that could have avalanched seemed to. Found some newer and hollow wind slabs in steep entraces that could have filled in after the first cycle of avalanches. Mostly cloudy day with some sun breaks. Light W winds and temps that hovered below freezing. Skiing was edgable and buttery at higher elevations, and surprising pleasant on much of the debris.
We observed 2 collapses in the valley floor as well as tons of debris from the widespread avalanche cycle. Nearly everything that could have slid did. Even slopes that are relatively low angle seemed to fracture.Weather

Light winds out of the west. No significant wind loading. Dont think there is much snow available for transport. Some light rimed precip this morning, but ending after a few hours. Sky was overcast in the am and cleared throughout the day, athough never went blue. Mild temps, with an air temp around -1C mid day.
Snowpack
Dug a put around 6500' on a NE aspect of Poster Bowl (Pika Bowl). Found about 100cm of precipitation particles above the 12/7 crust, with varying hardness (F-4F-1F- 4F). Got multiple resistant planar results @75cm down on what seems to be the old/new snow interface from before and after the AR event.
