This image was originally meant to track the movement of sand dunes near the North Pole of Mars, but what's on the ground in between the dunes is just as interesting!
The ground has parallel dark and light stripes from upper left to lower right in this area. In the dark stripes, we see piles of boulders at regular intervals.
This erosion has produced several small mesas and exposed light-toned material that may differ in composition from the surrounding material.
This image from NASA's Mars Reconnaissance Orbiter (MRO) shows blocks of layered terrain within the Olympus Mons aureole.
