Mars - The truth suppressed again

[Callidon]

After spending a lot more time looking at these pics, i realise my eyes were playing tricks, its not a top down picture but it is from a very acute angle. When you can actually se eit from the angle the pic was taken, you can see where the ridge lines are and that top centre a number of the lines face the opposite way, as the topography is different there.

I don't think these photo's are shpooed at all by the way.
