This shows that the martians had a very well thought out process of gathering together their creature's dead in extreme antiquity when they lost their atmosphere and their planets surface destroyed ! I really and truly think these diorama like floor sculptures in three dimensional form are memorials, in dedication when they lost their atmosphere way, way back in time!
Notice "hand gestures that might seem odd, but they are demonstrations of what their sculptures are about. Please notice "white" action markers that fit very nicely with the odd hand gestures!
Such as perimeters of containers done in the form of "white" lines to show hands going over and into them putting in my opinion dead sea creatures to stop the spread of diseases, lethal bacteria etc.
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!
