This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dusty terrain near the west rim of Malea Patera, located southwest of Hellas Planitia. The circular feature near the left (west) edge of the image is a filled and partially exhumed (and nearly inverted) impact crater which still shows a well-defined, raised rim. The dark streaks that run across the scene are tracks left by passing spring and summertime dust devilsâ€”a common occurrence in this area.
