Tulin (Chinese: 土林), meaning “earth forest”, is a form of geological clay formation. It takes the form of pillars which from a distance give the impression of a forest.
There are multiple examples of tulins in Yuanmou County in the Yunnan Province of China, in an area of about 50 square kilometers. The tallest formation has a height of 40 meters (130 ft). The features are one to two million years old.[1] The area was opened for tourism as the Yuanmou Earth Forest (Tulin in Chinese) in 1985.[2]
