Louros Valles

April 14, 2004
This image was taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express during orbit 97 from an altitude of 269 kilometres. The image has a resolution of about 13 metres per pixel and is centred at 278.8° East and 8.3° South. The colour image has been created from the nadir and three colour channels. North is at the right. The image shows a system sapping channels, called Louros Valles (named in 1982 after river in Greece), south of the Ius Chasma canyon which runs west to east. The Ius Chasma belongs to the giant Valles Marineris canyon system. The Geryon Montes, visible at the northern images border, is a mountain range which divide the Ius Chasma into two parallel trenches. The dark deposits at the bottom of the Ius Chasma are possibly related to water and wind erosion.
