Color-changing stalactite discovered in Phong Nha

Explorers have discovered a special stalactite which changes its color continuously, in the Phong Nha-Ke Bang natural heritage site of Quang Binh province.
The strange stalactite is in Huyen Khong cave, around 1,500m from the cage mouth. This stalactite changes its color very often, under lamplight.
It was discovered during an exploration of the length of Phong Nha Cave, which finished on July 30. The stalactite is around 2m wide, over 5m high.
Le Thanh Loi, director of the Phong Nha Culture and Ecological Tourist Center, said that this is the first time experts found such a stalactite.
Let’s discover the strange stalactite and the landscapes on the path to Huyen Khong cave.
