Comments: 

There were actually three different slides in the Wilson drainage, the first one looked to be animal triggered with animal tracks going in at the top and coming out of the debris at the bottom, this one was about 200ft wide and ran about 500ft, not sure of the timing. The second one occurred around 12:30 it was in the far left chute and could have been triggered by a ski cut as we saw someone headed that way on our first run on the Nipple. It looked to be around 60ft wide and ran 800ft. the last one was in Wilson Glade, not sure of the dimensions being that it was a long way away and in the shade but it looked like it went wall to wall with a fairly deep crown it might have been triggered by the same person because it occurred around the same time.

Photos: the first slide that was there when we arrived, the last photo is the slide that ran around noon, in the skiers left chute and in the background you can see the crown in the glade if you zoom in.
