Abstract
The study of hillslopes is a primary element of geomorphology and has successfully been used in many terrestrial arenas. In this study we take advantage of High Resolution Imaging Science Experiment (HiRISE) imagery as well as Mars Orbiter Camera (MOC) derived DEMs of the Pathfinder landing site to study regional hillslopes at resolutions many times greater than previously available and compare them with Mars Pathfinder lander images. This site was thought to be modified by massive flooding 1.8–3.5 byr ago and although evidence of flood activity was not obvious at the finer scale of this study, possible lee deposits and terracing were seen in some of the features. Evidence of post flood processes of ice related creep, aeolian and dry mass wasting were observed at the site and have likely obscured flood related morphology present in these features. Regional slopes were found to vary with aspect and suggest processes intensities operating at different orientations, possibly related to the prevailing wind direction, as well as the origin of the ancient flood event.
