Colour plan view of Moreux Crater in Protonilus Mensae
The crater, which is approximately 135 kilometres across, has been heavily eroded and changed by glacial processes. This is particularly visible on the rim and central peak. Its floor has been so deeply filled that the crater now only has a depth of around three-and-a-half kilometres. A belt of dark dunes forms a circle around the central peak. In these contrast-enhanced colour images, the dune sands appear bluish.
