Rock glacier in a double crater
Rock glacier in a double crater
A perspective view obtained by the HRSC on board ESA's Mars Express, showing an unusual 'rock glacier' in the eastern Hellas region. Ice-rich material seems to have flowed from a small, nine kilometre wide crater into a larger 16 kilometre wide crater below. The ice may have precipitated from the atmosphere a few million years ago.
This unusual structure with traces of a glacier is located in Promethei Terra at the eastern rim of the Hellas Basin, at about latitude 38º South and longitude 104º East. This view is looking south-east.
