Wind erosion is when wind removes fine-grained particles by turbulent movements. This phenomenon take place in places called deflation zones, almost half of the earths desert surfaces are stony deflation zones and they have different appearance due to the different movements of the wind. You can find “blowout formations”, “desert varnish”, “vardangs” and so on. What is interesting is that it is a trace of the negative of movements in contrast to stalactites formation where you actually follow the movements.
