Perspective view of an area west of Moreux Crater
Perspective view of an area west of the Moreux Crater, where the main branch of Ismeniae Fossae (top left) meets several lateral valleys from the east. Linear structures running parallel to the valley slopes and referred to as ‘lineated valley fills', indicate that glacial ice covered by rubble and debris pushed through the valley, leaving a distinctive pattern on the surface. An aggregation of small, round, sometimes elliptical depressions in the left foreground could be sinkholes, created by sublimating ice, or secondary craters that resulted from strikes by the ejecta from a large impact crater.
