2 parties of 2 skied ledge Couloir. The groups chose to join forces on the Bootpack, but ski the line separately. we noted a thin 10cm storm slab at the bottom, but this seemed to dissippate on the Bootpack(swim?) on the way up. The first skier triggered, a small sluff up high. I was 4th and last down. I chose to ski a line slightly right of the existing tracks, and had a Sz 1.5 storm slab fracture above me, and could feel it moving under me. I was carried about 40m down the Couloir, and was able to stay on the surface with all gear attached. As the debris slowed down I was able to stand up and scoot off to the left and out of the path.
