A yardang is a sharp irregular ridge of compact sand lying in the direction of the current wind in exposed desert regions.

Yardangs are formed by the wind erosion of adjacent material that is less resistant. Much like if you piled feathers on top of rocks and blew on them. The feathers would blow away, but leave the heavier rock shapes behind.
