A case of misjudgment because of desperation of water it sure seems to me ! This leans heavily on the fact that mars lost it's atmosphere in ancient times. What better reason for a story like this ! Hello !
You have to really ZOOM in and look. Martians ARE telling stories of their disasters and it has to be when they lost their atmosphere. Time and after time, photo after Curiosity photo displays this important fact. It can't be denied, just too much visual evidence!
What really is amazing to me to say the least is that the Martians are SO exacting in their detail, Every nook and cranny seems detailed, I even hate to write over their wonderful sculptured story dioramas because they have SO many stories to tell even in some areas I type over! And they display them like no diorama sculpture i've ever seen on earth !
Their use of "white" to accent movement, their use of "one eye larger" to indicate death, their use of "holes" to show they are testing the "white" area because the are desperate for water. The list goes on.
If you think these are just rocks, sorry to say and not really to offend you but you have to have rocks in your head. I mean that in a funny way so don't get too offended ! :)
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!
