    It Rained So Hard on Ancient Mars that Craters Filled Up and Overflowed

    Figuring out the ancient climate on Mars has been tricky. While evidence gathered from orbit and on the surface seems to indicate there must have been a lot more water on Mars early in its history, questions remain on how much water and in what form. A new study has now quantified the amount of …

    And, the hypothesis that the VM formed by liquid flow from rain, is equally unsupported. "Um, of course."

    My personal hypothesis is a combination of both, Mars cracked open and later flooding rains helped erode the walls of the ginormus valley leaving behind numerous dried up tributaries. The water falls must have been spectacular.
