Ius Chasma, Martian Mountain Ruins:

Ancient Mars Civilization Evidence #89-88

NASA says: "This image of Ius Chasma shows several landslide deposits and groups of sand dunes."

Landslide deposits? Groups of sanddunes?

 

Below is a closeup of the dunes surrounding the central crater. I have found no other images of the geometric anomaly above other than that shown.

Although a neat image, the dunes surrounding the central crater hardly show the profound geometry exhibited in the Mountain Ruins.
