Significant settlement since the end of the storm. Isolated collapse noted near treeline on many aspects and widespread collapse observed below treeline. Widespread surface hoar formation- 5mm typical.

Observed some post-storm large (D2) natural avalanche activity on northeast and east aspects below treeline. Obvious, but too far away for a close look.
