This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows part of Tithonium Chasma, a major trough at the western end of the Valles Marineris canyon on Mars.

It was taken during orbit 887 with a ground resolution of approximately 13 metres per pixel. The displayed region is located at the beginning of the canyon system at about latitude 5° South and longitude 280° East. North is to the right of the image.

Tithonium Chasma extends roughly from east to west and runs parallel to Ius Chasma. It ranges from approximately 10 to 110 kilometres wide, narrows in an easterly (top to bottom) direction and has a maximum depth of about 3.5 to 4 kilometres.

This image covers the eastern part of Tithonium Chasma. Along the slopes of the trough (centre), linear features due to erosion are visible. At the base of the northern wall, an apron of material has a longitudinal ridge pattern and may have been caused by a large landslide.

Dune fields are scattered throughout the trough, including the north-east portion of a crater. A string of depressions on the plains in the south-west of the image may be caused by surface collapse. These features are common to this region and extend parallel to Valles Marineris.

Nearby, prominent linear features are visible and may be faults associated with the formation of the Tharsis Rise, located to the west of Valles Marineris and extending to a height of 8 to 10 kilometres. Some of these faults can be seen faintly extending into the trough.

This colour images was processed using the HRSC nadir (vertical view) and three colour channels. Image resolution has been decreased for use on the internet.
