SUMMARY: This photograph was taken by ESA's Mars Express spacecraft. It shows a mountain in the eastern Hellas Planitia region with craters partly filled with debris. It's possible that the mountain was covered by glaciers in the past, which filled up the craters with ice and debris; the debris remained after the glaciers retreated. The craters are largely free of meteorite impacts inside, so it's believed they filled with debris less than a few million years ago.
