Today's VIS image shows a small portion of Dao Vallis. Located south of Hadriacus Mons (a volcano), this channel is approximately 1200km (750 miles) long. It has been proposed that heating of the region due to volcanic activity melted subsurface ice which was released to the surface to carve the channel. Dao Vallis empties into the Hellas Planitia basin.
