Quick Answer
A yardang is a streamlined ridge carved by wind erosion, usually in deserts. It often points in the direction of prevailing winds.
The Full Story
A yardang is a long, narrow ridge of rock or sediment sculpted by abrasion and deflation from wind-driven sand. Yardangs are common in extremely dry regions where vegetation is sparse and wind can act directly on the ground surface. They often appear as parallel ridges separated by grooves, all aligned with the dominant wind direction. Some impressive yardang fields occur in the Lut Desert in Iran and the Taklamakan Desert in China.
