Accident Report: 2021/11/14 Qizhongtian Waterfall Group

A canyoneer attempted to self-lower off of an anchor using three ropes tied together. The knots connecting the ropes jammed at the anchor’s rappel ring forcing him to abort his descent. He ascended using prusiks until he reached an overhang which he could not surmount, causing him to be stuck in a free hanging position.
