HiPOD: Not Madame Web

This image is of a hill in the Nepenthes Mensae region of Mars. The hill and surrounding ground is covered by numerous connecting ridges that create patterns resembling spiderwebs.

These ridges likely formed as minerals accumulated within underground cracks. Some of the ground surface was then removed by wind and/or water, revealing the mineral-filled cracks.
