It certainly an old find, but nevertheless it was not kept. Has found out still that that new, namely - pay attention to a place specified by an arrow. I think it there is an effluence what or liquids
Good work with the images guys, I wish I were half as good as you are with your detection of anomalous findings!
I've looked at these images over and over and I cannot see anything resembling bipeds. I can see what look like either Lizards or Snakes. My own opinion is that these creatures are either making the holes in the rocks, or, taking advantage of the holes that are already in them.
I have one suggestion as to what the steam or smoke may be. Do you think that it could be Urine? If we are to accept that there are indeed 'animals' moving about then these will need to defecate one would have thought.
Also, if we are to agree and accept that animals are existing on Mars then the follow up question has to be; On what are they feeding?
I really like this collection. I have seen(considering we all see different) in these pics and the ones i have in my collection, a lot of reptile like creatures ,dolphins and just recently a few contemporary humanoid type looking images peering out of those crusty type structures( am I nuts) which I believe are produced like bee hives or wasp nests. In skippers moving evidence the split crusty structure was closing up. They are so numerous. I believe that these are reused by other creatures. It is a very busy place and I have been considering the noise that all are making! It must be loud. Do the rovers carry weapons? Just asking as a newbie.
It looks to me over and over in your posts that the evidence points to an intelligent civilazation represented here. I also belive they like to carve into rocks to make there dewlligs. This last one clearly shows smoke. I would bet that most of the rocks are rather permiable and not that difficul to burrow into to. The "blueberries" seen every where may also hold a clue to what resources these people use.
