Mars Ocean

Mars Probably Once Had A Huge Ocean
UC Berkeley geophycists are providing strong evidence that Mars once had an ocean. Naysayers have argued that what appear to be ancient coastlines near the North Pole are too warped to be true seashores. The researchers claim, however, that this anomaly resulted from the tilt of Mars' spin axis 2 to 3 billion years ago, possibly because the weight of surface water made the planet tip like a weighted top.
