A Man Found A Hidden Amazing Cave-The Largest Cave In The World

Son Doong Cave has the largest cave passage in the world, and was only explored in 2009.Two large rivers, Khe Ry and Rao Thuong, join together to form Son Doong Cave. The cave follows a large fault line that's 100m wide, which contributes to the huge size of the passages. The Phong Nha Ke Bang limestone is around 400 million years old, but Hang Son Doong is less than 3 million years old. The cave has two skylights, which allow daylight into the cave. This enables the unusual formations like Phytokarst to develop, and also plants and trees to grow inside the cave. Spectacular sunbeams are often seen at the first doline. Mist and clouds usually form in the large cave passages and rise up to the dolines. Watch video here:
