•Manicouagan Impact Structure
One of the largest preserved impact craters on Earth, located in Quebec, Canada, at 51° 23' N, 68° 42' W; it was formed about 212 million years ago. An ice-covered annular lake, 70 km across, now lies within a ring of rock showing clear signs of having been melted and altered by a violent collision. The original rim of the crater, though now eroded away, is thought to have had a diameter of about 100 km.
It is about 462 miles (745 km) northeast of Montreal.
It is about 130 miles (208 km) northwest of Sept Illes and Seven Islands Bay.
