Comments: 
Collapsing of the surface hoar layer was noted on the hike up, and sure enough as we regrouped at the bottom of our run down a north facing low angle ridge we heard and felt another settlement. I looked over to the edge of the ridge where it steeply rolls over and the northeast facing slope had been remotely triggered from about 60ft away. The slide looked to be about 175ft wide and ran quite a ways down the slope into trees. It was interesting to pull slabs off the crown and feel how heavy and cohesive they were, sliding very easily on the surface hoar. Steep northeast facing terrain, below treeline, is very sketch right now.
