4th lap in cirque.We figured something small might go as already intentionally triggered a slab ne facing, sluffs n facing. Hourglass, partner triggerd loose dry from ridge entry, partner ahead of it and hooked riders left and dropped into hourglass w speed. 80% of sluff went right(not hourglass) the sluff then triggered a small soft slab in the other drainage. Between the sluffing n slabbing, fair bit of snow., Some is from a previous skier. From my vantage point i could see the slab shattering but no big crowns. Small, not deep.
