This is a colour-coded topography map of a portion of the western rim of the Hellas basin. The crater shown in the upper left is on the periphery of this larger impact basin. The edge of the Hellas basin is traced by a string of rocky peaks known as the Hellespontus Montes – revealed as the red/white ridge in this topography map thanks to their height. White and red show the highest terrains, while blue and purple show the deepest.
The image is based on a digital terrain model of the region, from which the topography of the landscape has been derived. The image was created using data acquired with the High Resolution Stereo Camera on ESA’s Mars Express on 13 January 2014 during orbit 12 750. North is to the right, east is up.
