 The cave river’s course is channeled by the beds of limestone¹. A weakness in the rock can allow the river to increase its gradient to flow in, providing a real challenge for the cave explorers. The downward rushes halted when the water table is reached. Here the slow-flowing river carves tunnels with a more rounded profile. This tranquil² world is home to specialized³ cave fishes, like the eyeless Golden Barb⁴. China may have more unique kinds of cave-evolved fishes than anywhere else on earth. Above the water table, ancient caverns⁵ abandoned by the rivers slowly fill up with stalactites and stalagmites. Stalactites form as trickling⁶ water deposits its tiny quantities of rock over hundreds or thousands of years. Stalagmites grow up where lime laid and drips hit the cave floor.

 

So far, only a fraction of China’s caves have been thoroughly⁷ prospected⁸. And cavers are constantly discovering new subterranean⁹ marvels¹⁰, many of which are subsequently developed into commercial show caves.

 

Finally, escaping the darkness, the cave river and its human explorers emerge in a valley far from where their journey began. For now the adventure is over. Rivers which issue from caves are the key to survival in the karst country. This vertical¹¹ gorge¹² in Guizhou Province is a focal point for the region’s wildlife.

 

This is one of the world’s rarest primates¹³, Francois langur. In China, they survive in just two southern provinces, Guizhou and Guangxi, always in ragged¹⁴ limestone terrains¹⁵. Like most monkeys, they are social creatures, and spend a great deal of time grooming¹⁶ each other.

 

Langurs are essentially¹⁷ vegetarian¹⁸ with a diet of buds, fruits and tender young leaves. Babies are born with ginger¹⁹ fur, which gradually turns black from the tail end.
