The Mangala Fossae trough is a system of outflow channels on Mars that bears evidence of lava deposition and catastrophic floods.
The HRSC on board Mars Express obtained images of this region centred at 17° south and 213° east on 21 March 2007. Mangala Fossae is is approximately 1000 km long, located south-west of the volcanic region Tharsis, where the highest known volcano in the Solar System, Olympus Mons, is located.
This black and white high-resolution image was derived form the nadir channel which provides the highest level of detail.
