Party of 4. Skied conservatively through West Ymir Bowl. Made a group decision to ski one at a time through the bowl as there was a persistent wind affected crust. First skier traversed across the guts to a safe point and did not notice any signs of instability. Signalled next skier to come across to safe point when they triggered the storm slab to release a size 1.5 avalanche and went with the snow for about 100m. Visuals were maintained the entire time and no injuries occurred. We all skied to safety points in a group and made our way back down and discussed our experience with ski patrol.
