Hong Meigui Yunnan 2002
Until 2001, there had been little interest in the caves of North Yunnan, but that year a reconnaissance expedition indicated an overall depth potential exceeding 4,000m - hence this return trip. At heights up to 4,935m, there were several areas of particular interest - the south of Nu Tiang Valley (near Liuku), the limestone peaks 20km W of Zhongdian and the hills between Lugu Hu and the Yangtse. The final phase concentrated on the Zhongdian area where the height difference between a resurgence cave and a high-altitude draughting cave was c.2,200m. The team returned home with plenty of scope for future exploration in the Province.
