More Tiankeng on the Ridge

China Scenic - - Special Report - Photo/ Shui Xiao­jie

On a moun­tain in Zhenba, we dis­cov­ered an­other tiankeng that was not listed in the Hanzhong Tiankeng clus­ter. The width of its open­ing is over 100 me­ters and its depth is over 200 me­ters. Like Quanziya Tiankeng, this tiankeng is also lo­cated on a moun­tain ridge that formed by a col­li­sion be­tween two plates. But how could a tiankeng de­velop un­der such cir­cum­stances and how did it pre­serve its orig­i­nal shape, rather than break up due to strong up­lift? Many ques­tions are wait­ing to be an­swered.
