The first was remotely (and unexpectedly) triggered from a ridge at 8550'. NE facing, about 30 degrees at the very steepest.

We kicked off hangfire at the ridge and took a look at the crown, which consisted of medium density wind-drifted snow, not very stiff. Weak layer was a very thin layer of surface hoar. Just seconds before triggering the slab, we dropped the cornice shown in image #2, with no results other than surface sluffing. The slope under the cornice was steeper and more north facing than the one which was remotely triggered… go figure.
