Cold. Windy and heavy snowfall at times.

Snowpack

Quick rec trip up Graham Gulch- 5" of new snow on the snow stake and more like 6"-8" up higher in the drainage. Snow felt dense. Which was surprising considering the cold temperatures. Wind had drifted snow in 12"-16" 4F+ hard slabs. Did note NSF on BTL and NTL sheltered slopes below the new 15cm of new snow. Small grain .3-.5 NSF. Several ECTN's on that layer of facets. Primary concern remains the Dec. 10 interface. Several ECTP<11 on the Dec. 10 layers 30cm below the surface. PST 20/100 on Dec. 10 layer. We experienced several collapses some propagating cracks 75 ft.
