Avalanche Details

While in the meadows, we looked up to the bowl and saw an avalanche that was currently sliding. Looked to have released under a cornice, no cornice debris was seen. Debris moved slow and looked/acted more like a dry loose, yet was on an actively loaded slope where a wind slab problem would be suspected.
