Was walking the ridge toward LSB when I saw a slide coming down the upper apron of Superior, looked to be triggered bye a snow boarder or skier walking west from the summit of Superior towards the SE facing. Talked to Cody Hughs who was up on the peak and he said the guy got too close to the cornice line and set of a wind slab after knocking a peace of the cornice off. Looked to be quite a few people up there that had a better look at it than me they might have more specifics on it. Did get one good photo of the crown though.
