First full day of our Valkyr Lodge week and two things jumped out at me:

- The cornices are the largest I've seen in 7 winters of working here

- We had a sudden planar shear 60 cm down on an east aspect at 2200m. This is the first "cash-register" shear like this I've seen in quite some time. It failed on a 5 cm thick layer of rounding facets and surface hoar. Previous groups have seen this shear but it has mostly been resistant in character so I suspect the surface hoar is spotty. There has been no avalanches on this layer here but it did make think a bit

20 cm of cold smoke here in the past 24 hrs.
