Zhijin Cave

A view of Zhijin Cave, the top of the "Six most beautiful Tourist caves in China", in Bijie, Guizhou Province, China, June 10, 2022. Zhijin Cave is 12.1 kilometers long, with a maximum span of 175 meters and a relative height difference of 150 meters. The total area of the cave is more than 700,000 square meters. This huge underground "heavenly palace" was developed in the lower Triassic carbonate rock 220 million years ago. Karst shapes such as helmet, tower, curl, pipa, waterfall and shield are carved. Different forms of dripping create different "decoration styles". The "overlord helmet" in the cave is 14 meters high and looks like the helmet of the ancient Chu Emperor. It is the only helmet-like stalagmite found in the world.
