These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the Dao Valles and Niger Valles, a system of outflow channels on Mars. The images were taken during orbit 528 in June 2004, and show the Dao Valles and Niger Valles areas at a point where the north-eastern Hellas impact crater basin and the Hesperia Planum volcanic region meet.
