This VIS image is located between the uplands of Aeolis Mensae and Aeolis Planum. This region of the Martian surface is highly dissected by wind action. The surface materials are poorly cemented and easily eroded. It has been suggested that the surface is comprised of volcanic ash deposits, sourced from the Tharsis and Apollinaris volcanoes.
