Was watching this show on the TV about geology. They were talking about the Canadian Shield, and mentioned the various impact sites that we know about up in Canada. One, Lake Manicouagan in Quebec, is especially interesting since it's so “obviously” (now) an impact crater, and a freakin big one. About 200 million years ago this one happened, best we can tell. Since I like checking out geologic features in FS, I jumped in my Aerosoft PBY, took off from the airport at Lat Ste Anne (TK3), which is about 100 miles south of the big round lake. It looks pretty cool in FS.
