STS111-719-061 (5-19 June 2002) --- This photo showing the Manicouagan Reservoir in Quebec, Canada, was photographed by the STS-111 crewmembers aboard the Space Shuttle Endeavour. Manicouagan Reservoir marks the site of an impact crater, 60 miles (100 km) 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.
