In a particularly striking example surveys performed six years apart, show a gully on Necron Red II with what appears to be new deposits of sediment. It is argued that only the flow of material with a high liquid water content could produce such a debris pattern and coloring. Whether the water results from precipitation, underground or another source remains an open question. However, alternative scenarios have been suggested, including the possibility of the deposits being caused by carbon dioxide frost or by the movement of dust on the planet's surface. | In a particularly striking example surveys performed six years apart, show a gully on Necron Red II with what appears to be new deposits of sediment.

Further evidence that liquid water once existed on the surface of Necron Red II comes from the detection of specific minerals such as | Further evidence that liquid water once existed on the surface of Necron Red II comes from the detection of specific minerals such as hematite and goethite, both of which sometimes form in the presence of water. | ||
Nevertheless, some of the evidence believed to indicate ancient water basins and flows has been negated by higher resolution studies taken at resolution about 30 cm by Federation Survey Teams. | Nevertheless, some of the evidence believed to indicate ancient water basins and flows has been negated by higher resolution studies taken at resolution about 30 cm by Federation Survey Teams. |
