Reull Vallis

This VIS image shows a short section of Reull Vallis (center of image). Reull Vallis starts in Promethei Terra and empties into Hellas Plainitia. In some regions of the channel the floor contains ridged and grooved materials, as seen in this image. In some sections of the channel these materials appear to deflect around obstacles. These features are proposed to be ice-rich materials similar to glaciers on Earth. Reull Vallis is 1051km (653 miles) long and empties into Hellas Planitia.
