This image taken by the High Resolution Stereo Camera (HRSC) on board Mars Express shows the mouth of the Tiu Valles channel system on the red planet.
The picture was taken in orbit 3103 on 10 June 2006 with a ground resolution of approximately 16 metres per pixel. The region is located at approximately 27° North and 330° East.
Its winding, meandering ridges, bound by depressions are eye-catching. The processes that formed these odd structures are unknown. Possibly, during floods events, water or water-rich surface layers came in contact with lava from the surrounding areas, which then might have led to the formation of these mysterious ridges.
The colour scenes have been derived from the three HRSC-colour channels and the nadir channel.
