For the record
here is a x-eyed view by hortonheardawho of "
Mars Rover Blog" fame.
Thanks for the link Maksutov,

Short frost periods were used to free salt water from ditches where it was then allowed to melt in the sunlight. In open waters, some of the salts initially begin to freeze with the water. However, over time, mass transport takes place throughout the semisolid layer as solidification continues to take place.

I fail to see how from this it can be concluded that brine can not exist on Mars. As Salt water can exist in Siberian ditches on Earth, why not on Mars? Ice sublimes on Earth but the water cycle ensures that it exists at all times on Earth. (note:water cycle <> rain)
I agree that the article seems to have misinformation as to "The imaging shows that the areas occupy the lowest parts of the terrain", but it would be totally illogical for anyone to claim that as a lie in a paper rather than as an error. No one would gain anything by lying in a scientific paper when it can be easily disproved. Has anyone considered that the image might not be part of the original paper and that there are many other "pond" like looking features imaged that may or may not be on a steep enough slope? I don't know the slope of
this cavity. I do know the waves on the feature are solid as the different channels of the color image were acquired minutes apart.

Gil Levin did great work on deleoping life detection experiments in the 60's that culimated in the Viking mission, But he has over the years become increasinglyt strident in asserting that his experimental results were not simply consistent with biology, but were definitely due to biology.

That would be a natural reaction to NASA's repeated official and false statements that all Viking tests were
negative.(note: negative <> false or inconclusive)
