Tulin (geology)

Tulin, 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 m. The features are one to two million years old. The area was opened for tourism as the Yuanmou Earth Forest (Tulin in Chinese) in 1985.
