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]
[4] [5] Most places on Earth have several weathering processes acting at the same time, so finding good examples of dreikanters is often difficult. Antarctica is a good location for finding such ventifacts since wind is usually the only active weathering agent.
Some geological processes can result in circular or near-circular features that may be mistaken for impact craters. Some examples are calderas, maars, sinkholes, glacial cirques, igneous intrusions, ring dikes, salt domes, geologic domes, ventifacts, tuff rings, forest rings, and others.

Ventifacts, like Jake Matijevic (rock), are another aeolian landform on the Martian Surface. [75] A wide variety of other sedimentological facies are also present locally on Mars, including glacial deposits, hot springs, dry mass movement deposits (especially landslides), and cryogenic and periglacial material, amongst many others. [69]
Taking into account various features such as ventifacts, the concentration of carbon-13 in the rock and other geological features, the sediments Thuchomyces is known from are interpreted as being a wind-blasted desert environment crossed by ephemeral streams, which was occasionally flooded.
