Textured Surface in the Southern Part of Trumpler Crater
This observation shows a frozen terrain typical at these latitudes. The surface is mantled by a deposit that is postulated to be largely a mix of dust and ice. However, many of the higher hills have had this mantle removed and the older rocks are exposed. In some parts of Mars there is good evidence for ice having !owed from higher to lower ground, but there is no such evidence here. Perhaps the mantling deposit never formed on the tops of these hills or it was preferentially removed from these places.
