Devil's City

The term "yardangs" comes from the Uighur language, meaning "steep hill", and now it refers to a landform of wind-eroded hollows, mounds, etc. When strong wind blows, queer sounds can be heard, so the spot was called a "devil city".

Due to long-term wind erosion, soft sands and small stones have been swept away, leaving behind regular gullies on the ground and standing earth hillocks of different sizes, shaped like human figure, horse, camel, tortoise, crocodile, pole, yurt, palace, castle, mushroom and so on.

When night falls, the wind gives horrifying howls as if the site was haunted by thousands of wild animals. While experts hail it as a geological wonder, the third one of its kind ever found in China.
