Well, considering glacial cycles can move vast amounts of liquid water around on global scales on the order of tens of thousands of years on Earth, then hundreds of thousands or millions of years on Mars isn't that out of scale, considering the orbital variations are roughly an order of magnitude greater than on Earth.
What this paper does, along with the recent volcanic chronology indicating relatively recent volcanism, is gives us our final rough description of Mars.
I say on to Ceres. It's a much shallower gravity well, and has an ocean of subsurface ice, which may very well be exposed at or very near the surface.
Michael Griffin is obsessed with Mars, we'll get a much better idea of Mars life in the very near future with the unmanned robotic missions we already have going.
Ceres is the place for humans. You want exploration? I've got a planet for you.
