HiPOD: Fluvial Landforms in Granicus Valles

In this image, large, streamlined features and grooves have been carved by enormous water volumes into the floor of Granicus and point to the direction of flow towards the northwest. The floods of Granicus Valles are thought to have formed later in Mars history during the Amazonian epoch, several billion years ago.
