Skied a few west and north laps in Lynx Creek finding a variety of surface conditions. On our last lap we skied the north chute/ginormous terrain trap from the summit of East Groundhog to Bench Creek. There was a visible wind pillow across the starting zone which the first two skiers cut with no result after which the third skier dropped in and triggered a slide basically immediately after descending past the ski cuts; picture attached. The slide broke at his feet. The slide was 80′ wide X 150′ long X 9″ deep and constrained to the wind loaded pocket, however the debris went 2500 vertical feet down the chute. I did not ascend to look at the bed surface, but thought it was noteworthy that it was the third skier who triggered it. No other noteworthy findings except for the twisted joy of watching the heli skiers lap the alders below us.
