I have to wonder if many of these photos are not "cleaned up" by Nasa ! Because I see an importance in understanding this "attaching" process. To display that the martians had to piece together all their dead when the calamity hit that destroyed their planet. These attached segments that are shown in the photographs below, they truly seem to be memorials to their dead in extreme antiquity ! In other words there must be "outside memorial floor sculptures" just like the cleaned-up photos below.
I think if it was the original it must have sand all over it etc. Just a guess though:^) I think this process must be very important to Nasa's (powers that be) ! I see over and over a passion by Nasa to clean-up important photos so we can learn, grow and start to understand martian's artistic - educational "outside martian floor sculptures". Many that tell stories but doing it in sculptured form without stone, but with easier material, make "algae" ? But clearly they can't be stone, not that they are not master's of stone, but maybe a material like algae?
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
