Harmakhis Vallis
Harmakhis Vallis is a valley near Hellas Planitia, Mars. It has been identified as an outflow channel, the site of catastrophic floods of water during Mars' past.
Gullies are also common on the wall of Harmakhis Vallis, as seen the image below. Some authors have suggested these structures indicate geologically recent flow of small quantities of water across the surface.

Origin.
Dao Vallis begins near a large volcano, Hadriacus Mons, so it is thought to have received water when hot magma melted huge amounts of ice in the frozen ground. Much of this water may have been released in very large "outburst floods". The partially circular depressions on the left side of the channel in the image below suggests that groundwater sapping also contributed water more gradually.
