I see over and over for years now, creature memorial sculptures that look like laminate plywood! Why? I help further the answer in image below, and in the appointed category: "Laminate Creature Memorial Look" !
Please go to that page for further explanation and urls to Nasa Mast-cam image!
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!
