Reull Vallis (Released 20 October 2004)

Reull Vallis is located in the Martian southern highlands, just east of Hellas Basin. This extensive channel system records an interesting fluvial and mass wasting geologic history of the area. Many images show interesting patterns of mass wasted material in the bottom of the channel.
