Section of the western rim of the crater Hellas
The direct view of the crater rim of Hellas shows a landscape with varied structures caused by various geological processes. In the raised rim of the giant crater there were enormous tectonic movements during, and immediately after, the impact, which extend in the form of steps into the interior of the impact basin. Later, material was repeatedly transported into the crater. This can be seen from the valleys, which are reminiscent of river beds, in which ice flows moved downwards and transported and deposited debris and boulders. The lower regions are covered with frost.
