Having read the diatribe of comments at the guest book aimed at Mr Skippers latest evidence, I felt I should comment on my own personal thoughts.
If you look at the wider image of Hellas Basin (very large download), the first thing to notice is that the majority of craters in the area are either partially or completely filled some with the geometric shapes that Mr skipper comments on.
I recommend viewers to download and view the JPEG images (Half way down the page), as besides the geometric shapes there is a lot of more anomalies to be found here than first meets the eye.
As Mars is an alien world we can expect geological feature to differ from those on Earth, but on closer examination at the anomalies surrounding the structures in Reprt#207 it is certain that some sort of artificial influence has taken place.
