Sunburst - could see an older crown on NW shoulder, around 2300'- this may have occurred last weekend due to how filled in the crown was. Lips, West face - small wind slab

Sawmill Creek - Across Turnagain Arm from Girdwood Valley - West aspect, 2500' - large slab avalanche
Placer - viz was pretty poor, but light was shining on the peak between Skookum and Portage, West aspect, 1500'- could see a few small steep terrain features with older crowns on them.
