Reported via text message. Actually reporting two avalanches in the same general area, both on steep rocky slopes and failed on PWL. Small one appeared to be skier triggered 2' x 20', the larger perhaps remotely triggered from a nearby uptrack.
I went up to the site on 12/19. Sure enough, the avalanche had failed on a buried persistent weak layer of sugary faceted snow above the Nov.12 rain/rime-crust.
A skin-track went along the ridge above the avalanche and then to the west and towards pt. 9248. I could see that the slope just below the uptrack and to the west had collapsed and cracked extensively but had not avalanched because of a lower slope angle. Cracks were visible across the slope, hundreds of feet away from the avalanche.
