Image Detail 3: Glacial flow structures between mesas
Traces of erosion, transportation and deposition of rock from the southern Martian highlands by slowly moving glaciers can be seen throughout the lowlands and valleys between the mesas of Deuteronilus Mensae. The texture of the surface indicates the direction of flow and the changes in direction caused by topographical obstacles, which ‘steered’ the glacier. In the centre of the image, an impact crater approximately 10 kilometres in diameter is visible. Its bowl-shaped structure has been completely levelled by sediment deposits up to the remnants of the crater rim.
