Manicouagan Crater is one of the oldest impact craters on earth, and is situated in the Cote-Nord region in Quebec, Canada. It is estimated to have been created over 215 million years ago, by a 5km (3.1mi) diameter asteroid. The crater is a 100km (60mi) diameter, multi ringed structure, with the most prominent feature being a circular lake, about 70km (43.4mi) in diameter. This crater also forms the largest in an array of craters believed to be a multiple impact event.
