The interesting shape gives the impression that it is carved on the surface of Mars. However, the Department emphasizes that this form has not been "stamped" by space ships, independent.co.uk.
It is a natural phenomenon that actually shows how Mars has evolved in history.
In the past, there was a huge mobile hill on Mars. Also, there was frequent eruption, and lava wandered through the dunes, but it did not reach its peak.
So when the lion is firm, the sand dune looks like a particular island with a sandy pile.
Now that the entire process has left a certain surface relief from the "red planet", you can see various shapes similar to embedded symbols or signs.
The photos were produced by NASA's HiRISE camera.
