China Supplement Summer 2006 EXPLORATION OF CAVES IN TIAN’E AND FENSHAN, GUANGXI PROVINCE, CHINA FOREWORD This publication charts the teams’ work over two expeditions in 2004 in Guangxi. It includes articles Arguably China has the most spectacular caves and karst which are both scientific and descriptive, covering in the world. Approximately 2.6 million km² of the surveys of nearly 50 km of cave passage. It has been country is karst, with about half of it (and most of the prepared for the club but a more comprehensive report mature karst) concentrated in the southern regions. It has been produced by the team which runs to 160 pages is therefore no surprise that expeditions are continually and contains additional material and photographs and drawn to areas in Guangxi where the sheer scale of goes into more technical detail.

THE EXPEDITIONs - By Ged Campion which had been the objective of the 2000 China Caves The Hidden River Expedition to Leye in 2002 Project, giving a logic to comprehensively explore this had revealed many exciting finds and yet again small corner of China’s spectacular karst. Both Tian’e demonstrated the huge potential for new caves in this and Fengshan held great promise, Tian’e with its area of Guangxi. Of particular note had been the big significant vertical range potential from its high craggy tiankengs and deep shafts, but the possibility of long, plateau to the river below, and Fengshan tantalisingly continuous, big cave passage stretching from Dashiwei near to the Bama district where the China Caves Project Tiankeng to the resurgence 20km away in the north at in 1988 had found continuously large cave passage with Beizhong had eluded the expedition. beautiful rivers and stunning karst features.

These include Wei Dong south-east of Tian’e town, the San Gui Shui Tiankeng further south, and further south still, Jiang Jia Tao which was the deepest cave found by the expedition with an entrance shaft of 180m. Interesting and complex vadose and phreatic caves were also found along the thin swathes of limestone to the south-east of Tian’e town. The team also explored a number of caves near Fengshan town, and then moved south to discover the massive cave passages of the Jiang Zhou Cave System.
