Title:
Manicouagan Impact Crater
Explanation:
Manicouagan Crater in northern Canada is one of the oldest impact craters known [ http://antwrp.gsfc.…]. Formed 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 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 [ http://www.lpi.usra…impacts.html ] on Earth [ http://antwrp.gsfc.…] and other [ http://antwrp.gsfc.…] Solar System bodies. Also visible above is the vertical fin of the Space Shuttle Columbia [ http://www.nasa.gov…orbiters/orbiterscol .html ] from which the picture was taken in 1983.
