Yincuixia (Shady Green Gorge) is a 600m long gorge with a river of deep green colour. The gorge is used for motor boat trips with tourists. The special thing with this gorge is the fact that it is a karst feature. It is a socalled cave ruin or roofless cave.
Obviously a roofless cave is a sort of paradox, as the definition of a cave requires the existance of a roof. If it is roofless, it is not a cave. This term is used to describe the formation of a gorge, which formed underground as a cave. As the cave became bigger and the roof thinner, the roof started to collapse. The karst windows were subject to intense erosion and grew fast, the roof shrank untill it became a series of natural bridges and finally those collapsed too. At the end there is a gorge with former cave walls, often - like in this case - with stalactites and other speleothems.
This valley is called Lovers' valley by the native Yi people.
