This stunning image features dozens of layers in the walls of a graben on the flanks of Arsia Mons. These layers could be yet unmapped volcanic units (lavas or ash deposits) and their identification can lead to a greater understanding of the history of this volcanic terrain. Material from this wall likely mantled the ice-rich deposits on the graben floor, and a 3D model can also characterize erosion patterns on the wall.
