About this image

This VIS image shows part of Medusa Fossae. Winds have eroded materials in this region, creating ridges and valleys aligned with the direction of the wind. These features are created by long term winds scouring a poorly cemented surface material. It has been suggested that this region of Mars provides a large percentage of the surface dust seen around the planet. Ash falls from nearby volcanoes may have been the source of the surface materials eroded into these and other wind eroded landforms.
