The floor of Hellas Basin is often obscured by atmospheric haze and dust, but it tends to be quite clear in northern spring and southern fall.
HiRISE images are revealing some very strange landforms on the floor of Hellas. Materials appear to have flowed in a viscous manner, like ice. Viscous flow features are common over the middle latitudes of Mars, but those in Hellas are often distinctive for unknown reasons.
