Observed a loose/wet avalanche of appreciable size around noon on superior, observed from a similar altitude below little superior. The slide was naturally triggered in the rocks looker's up-and-right of the upper apron. The slide crossed numerous skier tracks and slid through the central chute of the lower cliff band, leaving a debris pile of ~1-4' about 100' below the cliffs. All southerly aspects were considerably warm, even at ridge tops, and skier initiated rollerballs were growing to ~1 foot in diameter and travelling far. While driving down-canyon, fresh debris was also observed in several chutes on South aspects, including Little Pine, and below Monte Cristo.
