Comments: 

My partner and I found a cornice that we could safely cut off and drop onto a slope below to see if it would avalanche.  It produced a very large avalanche failing in the weak faceted snow near the ground.  This confirms my suspicions over the last few weeks that our buried weak snow is still very much capable of producing dangerous avalanches.

It should go without saying that it was obvious that no people were in the canyon below us.

There were actually two avalanches.  One that the cornice drop triggered and another larger one which was triggered sympathetically in the next path to the west.
