The master layers appear to be an accumulation of the work and toil of gathering the creatures together as close as they can ! Please notice how the layers in "yellow" appear to be connected to the many sections below in red and white, They appear to be representations of "lifting", pushing with arms, lifting with odd hands & arms to their final destiny with is the "master layers".
It is as if "yellow, master layers", is the accumulation of what is around it ! I've seem this odd scenario many times, but to me this photo seems to be a clearer demonstration in photo form!
Also, which is monumental, constantly there are larger layers that are full size and much taller. But these smaller floor-outside sculptures are representations of the much larger ones that don't have the gestures of pushing, lifting etc
The section in blue appear to be the dead creatures that are scattered and in need to be picked up and put in layers! But it seems that there are so many that they have to be put in layers that are higher because the earlier ones are put in the bottom layers!
Memorials to the dead creatures that were wiped away when mars lost it's atmosphere and the surface of mars destroyed in extreme antiquity !
Example of Master layer in full form!
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!
