Perspective view of a part of the southern crater rim
A valley up to four kilometres wide cuts through the rim of Moreux Crater. The flow structures running parallel to the valley slopes are remnants of ancient glaciers that flowed down the valley slopes, met in the middle of the valley floor and then advanced further down the valley, into the crater interior. The rock masses deposited on the slopes broke up, probably due to the gradient of the surface, and left behind the fracture structures visible in the foreground of the image. A thin layer of volcanic sand (shown here in blue) covers large parts of the crater floor.
