Manicouagan Reservoir Crater

Manicouagan Reservoir Crater
Manicouagan Reservoir Crater Around 214 million years ago, an asteroid about 5 kilometers (3 miles) in diameter slammed into what is now Quebec, Canada, creating a crater about 100 kilometers (60 miles) across. The impact caused a shock wave and air blast that would have killed plants and animals within at least 500 kilometers (310 miles).
