Description 1



This cave has a total length of 515 m, and may be the longest lava cave so far known in China (accurate mapping of caves at Jingpo Hu or Hainan Island may prove that some may be longer). The lava is dated as 0.512 Ma. The entrance of the cave is 1.4-1.8 m wide and 6-7 m high, although the ceiling becomes higher inside the cave. There is a hall 206 m beyond the entrance with a width of 26.8 m, broken by two rock pillars, each c.3.2 m high and a diameter of 4.5 m. In the main part of the cave sheet ice about a metre thick covers the floor, which has a general gradient of 2-5 degrees. There are stalactites on the roof and small amounts of breakdown. This is a very cold cave with a temperature between 0-5°C.
