VIDEO: Hidden Waters, Dragons in the Deep
Here is a powerful and accurate video about the karst of SW China. It features some folks that you may know including a couple of Chinese who have visited here in the USA: Chris Groves of the Hoffman Institute at Western Kentucky, Liu Hong, a very competent caver as well as karst scientist in Kunming, and Prof Yuan, the Grand Old Man of the Karst Dynamics laboratory in Guilin. http://www.circleofblue.org/waternews/2010/world/video-china-karst/ DirtDoc
