A central peak that has been heavily modified by glacial processes rises two kilometres from the floor of Moreux Crater. The formation of central peaks in impact craters is determined by gravity, the impact speed and – above a certain value – the size of the impactor. They are mainly found in craters with diameters in excess of around 100 kilometres. The large dune field of barchanoidal ridges can be seen to the northwest of the peak (upper right, in the background). Numerous individual sickle dunes (barchans) are distributed in a ring on the crater floor. In this contrast-enhanced colour image, the black-grey dune sands appear bluish.
