Remember, this is a 'negative' image of the area seen on Google Mars. The image has also been adjusted tone and colour wise to get to this point. I am pretty certain this does indicate there are large quantities of water on Mars and intelligent life. It now makes me wonder WHY those behind NASA are hiding this from everyone. This is not the only 'negative image' which shows hidden anomalies ...
UPDATE 19th March 2009 ... closer inspection of the sweeping lighter area in this image appears very much to be raging flames!!!
