A Yardang is a rock protrusion that has been shaped by the erosion of wind and sand, such that the upwind side is bluff or undercut, and the downwind part is a diminishing blunt ridge.

The compass part comes from the concept that the direction of the prevailing wind may be shown by analysing the effect.
