Perhaps More Tiankeng Exist
At the end of 2016, Shaanxi Government announced the discovery of the Hanzhong Tiankeng cluster, which includes 49 tiankeng of all sizes—one “super,” 17 large and 31 common. Yet, as surveys go deeper and become more thorough, more sinkholes have been found and are being assessed as to whether they meet the criteria for being a tiankeng. Perhaps in the future, the number 49 will be updated. These photos present some of the most typical tiankeng we have captured by camera lens. Each of them is distinctive.
