Nandan 2005 by Thomas Matthalm
Hidden Earth 2005
Nandan is a cone karst area with multiple levels of large, often well-decorated, fossil phreas intersecting sporting stream passage. It is also home to China's colourful Baiku Yao minority nationality. This year's expedition mapped over 10km, bringing the area's total to 30km and continuing the downstream exploration of the Nandan River.
