In the far lower right of the above image, a particularly picturesque mesa can be seen as the upper right of the two mesas visible there.

Better images show it to be just an interesting mesa.
Such complex looking landforms in the Cydonia region are thought to be the result of landslides and erosion of the ancient Martian crust.
