Title:
Manicouagan Impact Crater on Earth
Explanation:
The Manicouagan Crater [ http://www.linkdire…] in northern Canada [ http://www.odci.gov…] is one of the oldest impact craters [ http://observe.ivv.…] known. Formed during a surely tremendous impact [ http://antwrp.gsfc.…] about 200 million years ago, the present day terrain supports a 70-kilometer diameter hydroelectric reservoir [ http://www.ilec.or.…] in the telltale form of an annular lake [ http://epod.usra.ed…]. The crater itself has been worn away by the passing of glaciers [ http://www.glacier.…] and other erosional processes. Still, the hard rock [ http://duke.usask.c…] at the impact site has preserved much of the complex impact structure [ http://antwrp.gsfc.…] and so allows scientists a leading case to help understand large impact features on Earth [ http://www.lpi.usra…] and other [ http://antwrp.gsfc.…ap960906.html ] Solar System bodies. Also visible above [ http://earth.jsc.na…] is the vertical fin of the Space Shuttle [ http://antwrp.gsfc.…] Columbia from which the picture was taken in 1983.
