I also know there is shortage of water on mars. I do think there is a civilization underground on mars and in the Ernest Norman book : "The Truth About Mars", the martians have about 2000 years left until they can come up with a better Idea to find water. It does say in that book they tried to establish a colony on earth but it was not practical !
It is odd that you see imprinted on the top of the pillar containers like they possibly could be in the process of searching (like vultures are searching) ! Like they are thirsty for water? Why the imprinted object on the vultures wing (the hot sun)? I sure see martian stories in sculptures on mars as well ! Sure, I don't know the exact meaning, but for sure in Gobekli Tepe and on mars they ARE TRYING TO TELL STORIES IN THEIR SCULPTURES!
Notice how the fancy designs under the containers and out of the right of the designs right under the container is what could be a vulture. And another bird head-neck imprint with what looks like an arrow pointing towards the two legs . One thing that sticks out about mars sculptures are arrows! Arrows on mars seem truly to play as directors in mars diorama sculptures. I see that a lot of arrow type imprints through the mascam images especially! And I have put many of them on my site!
Again, does the attachment in the imprint of the vulture under the containers been the holders of the containers are searching as well? Searching for lack of something? Like water? Mars in short on water except the polar ice caps.
Afte mars lost it's atmosphere, don't you think they the martians would be searching for food and water for their survival on other planets? And if they are hundreds if not thousands of years ahead of us in technologies such as space travel they could come to earth with ease. Don't forget the Gary Wilcox testimony where he claims to have spoken with martians on April 24th, 2015, 10:30 am. They were carrying silver like trays he mentioned because they were in the process of studying plant life on earth.
"Carrying trays", on top of the pillar in the image below it looks like intelligent beings are carrying containers !
This is from a sculpture on Mars ! http://mars.jpl.nasa.gov/msl-raw-images/msss/01074/mcam/1074MR0047240010600081E01_DXXX.jpg
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!
