Martian Running Water
There is plenty of evidence for running water on Mars. But this evidence suggests that the nature of flowing water on Mars is nothing like it's terrestrial counterpart. The evidence is in the form of:
An analysis of this evidence suggests two possibilities
for the way the Martian water cycle may work.
