Landscape features in Utopia Planitia
Landscape features in Utopia Planitia
The annotations on this HRSC Mars camera image highlight special features in this region. On the left, branched depressions form a polygonal pattern (polygonal graben structure), possibly created under water. In the centre, a small impact crater (small impact crater) is framed, which, like the large crater (large impact crater with ejecta) in the top right, has a characteristic ejecta blanket indicating subsurface ice. Additionally, the large crater shows concentric crater fill, also suggesting ice, this time in the form of glaciers. In the lower box, scalloped depressions are visible – another typical landform of periglacial regions.
