This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a complex of overlapping, inverted channels in a fan exposed by erosion, then mantled by dust, in the Aeolis region of Mars. Aeolis exhibits an abundance of inverted channels and fan-shaped forms, largely created by a liquid such as water, and then preserved in layered, sedimentary rock that has been subsequently eroded by wind.
