The Mangala Fossae trough, 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 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 colour scene has been derived from the three HRSC-colour channels and the nadir channel.
