Yunnan 2004 was a 7-week, 17-person summer caving expedition (July- August) to explore known entrances and to search for new entrances on the mountain tops 2,300m higher, between the Yangtze valley and the town of Zhongdian. The expedition covered a large area and logged 240 new entrances. The deepest, C3-294 (Dawa Dong), was explored to a depth of 130m. Exploration at the limit was slowed significantly by a tight rift requiring hammering, but no termination was reached.
