This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, shows a detail of the Medusa Fossae formation. The Amazonis Sulci, with its ridges and grooves, appears to be wind-sculpted. The lack of craters superposing this surface indicates that wind erosion has been the latest stage of eroding processes acting here.

The HRSC obtained this image during orbit 917 with a resolution of approximately 13 metres per pixel. It shows an area located at about 5º South and 213º East.
