In a book that was created because of a telepathic experience in my opinion was written by Ernest Norman. He claims he was contacted by a being that lives underground on Mars. His name is claimed to be Nur El. Ernest Norman states that he was contacted by this Nur-El and he stated that the Martians receive their water from the pole areas of Mars. "The Truth About Mars Book": https://unarius.org/index.php?page=the-truth-about-mars
And I find it interesting that in an article from ESA that they claim through the Mars Express Orbiter that they found evidence of water indeed at the South Pole of Mars!
And in Ernest Norman's book in communicating with this Martian leader "Nur-El" that Ernest stated that indeed they (the martians) obtain their water from the poles. In page 32 of the book "The Truth About Mars" He "Ernest Norman" writes: "Water is very scarce on this arid planet most of the precipitation falls at the poles". Here is a photo of the quote by Esa and url to the article: https://www.esa.int/Our_Activities/Space_Science/Mars_Express/First_evidence_of_planet-wide_groundwater_system_on_Mars
Ernest Norman's book: "The Truth About Mars", was written way-back in the 1950's
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!
