Scientific paper

Ares Vallis is one of a vast system of unconfined outflow channels that emerges close to the equator at 18 degrees W, and is likely to be the landing site for Mars Pathfinder. Extensive studies have been performed to determine the sedimentary history and geological development of Ares. These suggest that until 3.5 Ga ago Ares may have been formed by glacially-related processes, with some fluvial activity, and that localised volcanic resurfacing followed until 1.6 Ga ago at more northerly locations. As an extension to these studies, this abstract describes the generation of a DEM for this region. The DEM indicates Ares is approximately 1.5km deep, between -2.5 degrees S to 7 degrees N and 17 degrees W to 19 degrees W.
