Came across some hikers headed back to Hwy 542 who had camped near the ridge on 12/18/21 and warned us of avy debris in the chute at the main stream crossing. It wasn’t there when they went up on 12/18/21, so it must have happened either evening or early morning today (12/19/21). No remaining slabs were visible and everything looked stable, but the debris was quite considerable.
