“Yardang” doesn’t sound like a typical scientific term (in English, anyway), and it isn’t. It’s Ugyur for the same type of rock formation on Earth, and it was first used by geologists to describe these desert features near Dunhaung in China.
Today, this is a national geopark and may soon join the global UNESCO network.
