This slide on the north side of Moffit Peak occurred in thin rocky terrain similar to other slides in the area from the recent storm. It is likely that very strong winds and heavy snow overloaded the slope creating this rather large slide. It is very possible the entire snowpack pulled-out with this slide, yesterday's winds have filled in some of the bed surface, but given the weak and thin snowpack that has been in these types of places all season, my guess is that this avalanche went to the ground.
The debris ended up out onto the flats below and a slide you would not want to get caught in.
