Manicouagan Crater Lake

Buzzing around Google Maps today, I noticed an almost perfectly circular lake in far north in Quebec. A Wikipedia later, and it turns out that the lake is actually a reservoir. As for the shape? The reservoir fills the impact crater left by a meteorite believed to be 5km across that hit the earth approximately 214 million years ago. Scientists believe that the strike may have been one of three that occurred all around the same time.

Were it not for the completion of the Daniel-Johnson Dam in 1970, this crater would remain as illegible as the other two. With the filling of the reservoir, the topography of the crater was written clearly on the face of the Earth, visible from space and called the Eye of Quebec. Looks pretty cool from the ground too.
