Edge of Olympus Mons
Edge of Olympus Mons
PSP_003476_1940  Science Theme: Volcanic Processes
This image captures a small piece of the southern edge of Olympus Mons, the largest volcano in the Solar System.

A pair of deep valleys can be see in the middle of the image, probably formed by ancient landslides. However, more recent lava flows have entered into the valley. These lava flows traverse the floor of the valley and feed a broad fan of lava flows at the mouth. The dark streaks along the valley walls are locations where the bright dust has been removed by small dust avalanches.
