The nadir channel, the field of view of which is which is directed vertically down onto the Martian surface, provides the highest image resolution in the High Resolution Stereo Camera (HRSC) camera system. During orbit 9465, the ESA Mars Express spacecraft was about 400 kilometres above the surface, resulting in an image resolution of 16 metres per pixel. To improve the depiction, the resolution in the images shown here has been slightly reduced; north is to the right.
In the framed areas, conspicuous phenomena characteristic of the region are visible: elongated, parallel flow patterns in valley-shaped depressions (box 1), hills around which plastic material has flowed (box 2), and partially filled impact craters in which the flow structures are aligned parallel to the crater rim (box 3).
