Ventifacts have also been discovered on Mars, where such sharp immobile rocks have caused significant damage to the wheels of the Curiosity rover. [4] An example of a Martian ventifact was named Jake Matijevic. By analyzing its shape, it was possible to reconstruct the main wind direction which sculpted the rock. [5]

Ventifacts, like Jake Matijevic (rock), are another aeolian landform on the Martian Surface.

Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).
