Mars May Have Had Glaciers Like Earth's

January 21, 2006|From Times Staff and Wire Reports

Mysterious debris fields found far from the poles on Mars were made by glaciers, possibly formed just like glaciers are on Earth -- by the buildup of snow, researchers from Brown University reported Friday in the journal Science.

The glaciers would have resembled those found on Earth in places such as Mt. Kilimanjaro in Africa or the Andean peaks in South America, the researchers said, and probably formed when Mars was tilted on its side five million years ago.

The sun's light would have caused moisture frozen at the poles to evaporate and fall as snow elsewhere on the planet, they said.
