This image shows scarps (steep slopes) in Deuteronilus Mensae, a region of distinctive terrain in the northern hemisphere of Mars. Polygonal fractures, possibly formed by thermal cycles in ice-rich ground, are visible throughout the scene. The high-standing topography at the top of the scarps have several muted circles. These are remnant impact craters that have degraded throughout time. Their degradation process might have been enhanced by the presence of ground ice.
