Photo: Impact Crater: Manicouagan Reservoir in Quebec, Canada As Seen From Orbit

This photo showing the Manicouagan Reservoir in Quebec, Canada, was photographed by one of the Expedition 30 crew members aboard the International Space Station.

The Manicouagan Reservoir marks the site of an impact crater, 60 miles (100 kilometers) wide, which, according to scientists, was formed 212 million years ago when a meteorite crashed into this area. Scientists say that over millions of years the many advancing and retreating glaciers and other erosional processes have worn down the crater.
