Giant karst sinkhole cluster found in Guangxi

Bottazzi Jean thought these objects appeared over 100 years old. He was much amazed how people could get into the sinkhole without the help of modern equipment as no more paths were found to reach the cave.

His team also discovered a limestone cave filled with grotesque and delicate stalactites.

"What we have seen in the cave is definitely a gift of nature, a masterpiece cultivated for billions of years on the earth. So the only thing the local government should do is to cherish and protect these treasures," said the French speleologist.
