The county also is home to several Tiankeng features.
These are large deep doline depressions with vertical sides that often
give access to the cave systems below responsible for their formation.
The team hope to visit this area and explore the tiankengs at Hailong
It is worth noting that the Jiang Zhou System also emerges into Bama
County at Dalue. On the Oct/November Expedition the system was explored
from this entrance and an initial recce of the area came across further
significant entrances in its vicinity. The prospect of unravelling the
mystery of ancient underground water courses that are no longer connected
remains an attractive option for exploration.
