Features of Juventae Chasma (2)

Caption NASA originale:"Among the more interesting aspects of this image are the dunes of sand that appear to be migrating over the top of the mound, and a flat-surfaced, plateau/mesa forming unit covering the North-East side of the mound but also seen within valleys to the North and along the Southern margin of the mound. This unit may be the marker of an ancient erosional surface. In this image, North is towards the top and the Sun is coming from the left".
