Sediment-filled craters in Promethei Terra
Sediment-filled craters in Promethei Terra
Glacial ice has had an effect on the landscape of not only Reull Vallis, but also in the mountains and craters of the adjacent Promethei Terra region. As with glaciers on Earth, ice masses start to flow and creep into lower lying regions, following the topography, under the pressure of their own weight and that of the boulders that have fallen onto them. After the ice disappeared, the sedimentary cargo was left behind. The pattern on the surface has been reproducing the flow movements ever since.
