Water has poured down along fractures in the rock wall over centuries and calcium carbonate in the water has continuously precipitated, resulting in the layer-shaped accumulations nicknamed Stone Curtain.
Calcium carbonate in vadose water (that is from underground, above the water table) settles down along the karst cave wall, forming curtain-shaped layers that look like a Buddha statue, called Buddharupa in Buddhism.
On the way to the Lion Cave are plank roads built into the cliffs above the gushing Luoshui River. In ancient times these roads, located on the ancient Shu Path, and that were first built in the Qin Dynasty (221-206 BC), led to places such as Chang'an (today's Xi'an, Shaanxi province), Chongqing and Langzhong in northern Sichuan.
