This image, obtained by the HRSC on ESA's Mars Express, is a mosaic of overlapping images gathered during five separate orbits. The ground resolution ranges between 10-20 metres per pixel, depending on location within the image strip, and the crater is shown lying near 51° South and 329°East. North is up.

The image shows Crater Galle containing a large stack of layered sediments forming an outcrop in the southern part of the crater. Several parallel gullies, possible evidence for liquid water on the Martian surface, originate at the inner crater walls of the southern rim.

This false-colour mosaic of Crater Galle was derived from three HRSC colour and nadir channels gathered during five overlapping orbits.

The crater's interior displays a surface shaped by aeolian (wind-caused) activity as seen in numerous dunes and dark dust devil tracks which removed the bright dusty surface coating.

Close-up view of Crater Galle, lying to the east of the Argyre Planitia impact basin and south-west of the Wirtz and Helmholtz craters, at 51° South latitude and 329° East longitude. The image clearly shows a large stack of layered sediments forming an outcrop in the southern part of the crater.

Several parallel gullies, possible evidence for liquid water on the Martian surface, originate at the inner crater walls of the southern rim.
