Third skier on slope. Second skier noticed very heavy pinwheeling and a sudden change in snow density, moved to side. Third skier triggered a small avalanche that ran heavily until it flattened into a gulley. Sudden change in snow density caused by warming. Skied a much more technical (avalanche-wise) run North facing with no warming avalanche issues earlier in the day.
