Transforming Friday with Nature's Wonders

Hello Toads - let's go to Hang Son Doong, Vietnam!

Hang Sơn Đoòng, "Mountain River cave" in Vietnamese) is a solutional cave in Phong Nha-Kẻ Bàng National Park,  Vietnam. As of 2009 it is the biggest known cave in the world. Inside is a large, fast-flowing underground river, it's formed in Carboniferous / Permian limestone.

Sơn Đoòng Cave was found by a local man named Hồ-Khanh in 1991. The whistling sound of wind and roar of fiery stream in the cave heard through the entrance as well as the steep descent prevented the local people to enter the cave. In 2009 it became internationally known when it was explored and surveyed by a group of scientists. 

According to the Limberts, (scientist couple that led the survey), takes the title of the world's largest cave. It contains some of the tallest known stalagmites in the world, which are up to 70 m tall. Behind the Great Wall of Vietnam were found cave pearls the size of baseballs, an abnormally large size.
