Was sledding on top of a cut block and cracks propagated off our sled tracks causing the cornice/wind and storm slab to let go. Couple different spots let go. Crown was 120cm to almost 3m deep in one spot. Couple hundred meters of the bowl in total. Was hard to tell exactly how far it ran as we weren’t getting close to the edge to look but looks like it got hung up in the trees for the most part. As we followed our tracks back we notice numerous cracks coming off our tracks.
