A very weak snowpack exists in this area. The 8-10" of new snow was begging to overload the weak snow underneath and widespread cracking and collapsing were observed. On steeper slopes or where the wind was building slabs, I have no doubt that avalanches would have been easy to trigger.
Steady S1-2 snowfall throughout afternoon tour, with accumulation of 5-7cm between 1400 and 1800.
No avalanches observed, aside from micro-avalanches on small rollovers, but we had very limited visibility.
Impressive collapsing and shattering of slopes, particularly as we climbed higher where there was more older snow to smooth out the terrain. Thanks to ongoing snowfall and poor light it was difficult to tell how far these were traveling, but in a few instances it was evident that these were running 100+m across and upslopes. Remote triggering would certainly have been on the table where the wind was building a slab in steeper terrain.
