Also, easily identifiable is the circular Manicouagan Reservoir - created by damming a river for hydro power (about 5000 MW in a series of 4 dams). The circle is the eroded remnant of a crater created by a meteor impact some 200 M years ago. -- "I was gratified to be able to answer promptly, and I did. I said I didn't know." -Samuel Clemens. |

Screw all the evidence. We all KNOW that global warming is a hoax! It's just a coincidence that the warmest years on history have occured since 2000. Besides, science is just a bunch of nunmbers. Don't mean nuthin'. Betcha can't wait to vote for Santorum. |

IOW, how did damming the river ensure that the water would remain in the circle? Did they build an artificial outer wall? http://en.wikipedia.org/wiki/Manicouagan_Reservoir The article on Wikipedia explains it as "an eroded crater". Since 214M years there has been an ice age (or more), tectonic uplift, etc. as well as plain old erosion. (Compare to Arizona's "Meteor Crater" which is only 50,000 years old - eg: over 4,000 times older.) No walls. AFAIK, a single dam formed the lake from the existing crater by damming the river to the south. In terms of ROI to backup some water for power, probably one of the best. I guess the surveyors and engineers did a great job in picking out the site and studying its potential. -- "I was gratified to be able to answer promptly, and I did.
