Description 1
Qiao Ban Dong
A track contours the doline-valley between Bai-Mo and Qian Dong and passes over the resurgence which then flows across the doline to sink in the lower level of Bai-Mo Dong. The resurgence itself is a deep lake which leads to a sump, with inaccessible passage visible high above which can be reached by diving through vegetation by the track and descending a 6m climb (Figure 6). This leads, via a mud-covered boulder slope, up into a heavily stalagmited area, then down into a chamber where a shaft drops to water level. A wide, low section with a seasonal raised sump then leads through into a spacious, sand-floored passage. The sand peters out and it then becomes difficult to avoid the shark's tooth corroded limestone which follows. Between the
minor pits and spikes lurk deeper holes which drop 15-20m to the permanent water level. After these, is a large, black pit with a lake at the bottom, reached by a 24m pitch and a large deep canal connecting to Limo Dong. Beyond the connecting hole, the upper passage rises and the strong draught is lost. The end is a hot-air dome, with a very large 20m deep hole to the water level almost blocking the passage. Speleothems prevent progress much further.

Analyse : BBS
Bama County contains a large hydrological system with associated caves, draining into the Pan Yang River, a tributary to the Hongshui. The Pan Yang cave system between Beimo Dong (main sink) and Fulong Dong rising was surveyed over 16 km, with passages as high as 145 m and 80 m in diameter. A total of 16 caves and 17 km of passages in Bama Co. were surveyed (10 cave surveys, area map, speleol.map, phot.). (RB)
