Floods on Mars

Scientist have found that great floods on Mars took place more "recently" (~10 million years ago) than previously estimated. A liquid surge, more water than that contained in Lake Erie, erupted over the surface carving the Athabasca Valles. This may be significant because these eruption sites may be important targets in search for Martian life. In addition, these sites could periodically provide doese of heat and water on Mars.
