Unnatural looking Hexagon Structure spotted in Pyramus Fossae on Mars

A hexagon shaped structure with a possible dome has been discovered in a photograph taken by NASA’s Mars Reconnaissance Orbiter on 17 August 2008 and is described as 'Possible Olivine-Rich Terrain.'


Jean Ward shows us, besides the hexagon structure, other unnatural looking structures that don’t fit in the surrounding landscape.

These strange structures, especially the hexagon structure, indicate that this area was once inhabited?
