When I was a kid, I did lots of crazy science experiments. Like utilizing the Sun's energy through a magnifying glass to bake potato bugs. What does that have to do with Mars? Nothing, but one time I remember spitting on some dust dirt. I then covered the puddle of spit with handfuls of the same dusty dirt. Anyway, my point is that the dirt formed a shell around the spit, which allowed me to pick it up and hold it my hand without getting spit on my hand.<br /><br />It could be that Mars has similar processes involved. The water excretes from underground, come in contact with the coco powder dust on the surface of mars, and then gets cocooned in minerals then freezes. If you look closely at some of these flowing reservoir photos, you will see large bubble/blister like regions that could be cocooned water ice.<br /><br />Anyway, it would be fun to analyze the data first hand. I am sure NASA is not releasing everything to the public, not as conspiracy or anything, just because of time constraints and practicalities.<br /><br />There must be hydrothermal vents and springs on Mars somewhere, and the flowing streams could be cocooned in water tubes, like lava tubes, and occasionally they breach the surface, only to boil and get cocooned again in coco powder dust. <br /><br />We should be able to see trace evidence of water flowing downhill through a water tube? These tubes should flow at or near the surface of mars, and they would look like veins or blisters protruding up rather than valleys and lakes that are dented.<br /><br />---Jatslo<br />
