In this paper we present part of an ongoing study to telemetry data of Phaethontis, aregion in the western hemisphere of Mars' Southern Highlands. in particular, we focus on an approximately 57,000 km2 area in Gorgonum Chaos. We selected THEMIS visual, MOC narrow angle and MOLA data abvailable from the Arizona State University and Malin Space Sceince Systems web-sites. We carried out multi-level processing of THEMIS and MOC data using the ISIS software and prcessed MOLA gridded data by the GMT software. After processing we input the images into ArcGIS software, We observed, identified and described, both 2- and 3-dimentionally, impact craters, chaotic and polygonal terrains, grabens and gullies. These landforms suggest a complex geological history involving sedimentary and tectonic processes such as meteoritic impact, the presence of underground water and ice, desiccation or freezing of wet sediemnts at least two episodes of extension, and recent aeolian activity.
