Oblique perspective view of a heavily weathered crater in Nilosyrtis Mensae
Erosion by water and ice have left rounded mountain tops and mesas in Nilosyrtis Mensae. This former impact crater became shallower and shallower over time due to fluvial and glacial erosion (erosion by water and ice) and the deposition of eroded material and windblown sediment. The crater relief has now all but disappeared.
