snowmon - Check out the Manicouagan Crater or Manicouagan Lake in Quebec. It is the largest "visible" impact crater at just over 70 kilometres wide. It is believed that a meteor broke up before hitting the earth and actually made 5 impacts with the others being in France, Ukraine, Manitoba and North Dakota. If this is true, you don't want to shatter the earthbound meteor into little pieces as they do in so many of those "impact flicks".
Check out the images on the internet. If you didn't know it was an impact crater, you would probably guess a flooded volcanic dome as it forms a nearly perfect circular ring lake.

I've read about it and seen pics taken from the air and also on the ground. I think science regarding meteor/comet impacts is growing at an incredible rate. Nobody wanted to believe that meteorites and other space bodies struck the earth, once they got over that hurdle, and learned to recognize characteristics, they are finding them everywhere, and it seems that mass extinctions often correlate to some of them found. That theory was pooh-poohed for years. Now the pendulum is swinging the other way and it seems everybody is doing research on impact events. fascinating stuff, I can't seem to get enough.
