This VIS image shows a long section of Reull Vallis. Reull Vallis starts in Promethei Terra and empties into Hellas Plainitia. On the floor of this channel are ridged and grooved materials that seem 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. Orbit Number: 84794 Latitude: -38.2433 Longitude: 111.672 Instrument: VIS Captured: 2021-01-25 05:11 https://photojournal.jpl.nasa.gov/catalog/PIA24716
