In the main image, which covers a patch of ground almost the size of Belgium, the yardangs all slant in the same direction due to the prevailing wind, curving in from the bottom left (south-east). They sit at the northern end of the Eumenides Dorsum mountains, which have been seen before by Mars Express; these mountains extend far out of frame to the west (top) of an especially volcanic region known as Tharsis, and form part of the huge, immensely dusty Medusae Fossae Formation (another familiar feature).
Where features meet
This image also captures two other fascinating forces of nature we see on the Red Planet, with all three coming together to meet just left (south) of the large crater to the right.
First is the crater itself, which looks reasonably fresh and is surrounded by a large, wavy-edged blanket of material (‘ejecta’) that was thrown out during the impact that created it.
