For much more information go to category : "Crashes"
But while you are here reading, look the finer details of the "white" off to the lower right of the image ! Then read in the category "Crashes" of what I say about it ! Also study the flow patterns of what looks like sand! In many cases I think those "waves" are made of a type of martian fabric. So "waves" can help lead to the segmented stories done in diorama like sculptured form !
In some instances yes, it could be altered by Nasa, but I think and have evidence that the Martians DO use fabric under many of their sculptured story dioramas! And also they lead away from their segmented sculptures!
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!
