On the way out of Tian Ping Miao Tiankeng.
Derigging the traverse line into the tiankeng, since we didn't find any more leads continuing onward from there.
Wind blowing through the constriction between Da Luo Dang Tiankeng and the miners' passage that we dubbed "Walk the Plank". (Due to a number of wooden stempels found to ease traversing at specific levels through rifty passage.)
