There’s a few notable crater lakes in Quebec. My favourite by far, though, are the Clearwater lakes/Lac Wiyâshâkimî in the far northeast. Two impact craters almost right on top of one another, now filled with water. What makes them really interesting to me is that they aren’t caused by one space rock breaking in two just before hitting the ground. The two lakes have been proven to be created almost 200M years apart, which means two separate asteroids hit almost exactly the same spot, separated by 200M years or so.
