Pit found by Quebecer confirmed to be a 390-million-years-old meteorite impact crater
MONTREAL — In late 2023, amateur astronomer Joël Lapointe was using Google Maps to plan a summer road trip when he stumbled upon a strange looking pit.

Hi Howard, I'm also interested in impact events. Working on my first novel and there's an impact event in the distant past that is key to the world building. Did you discover this cool website at Purdue U. ?

I’ve played w this site for the past 20 years. While they offer zero warranty on any accuracy as it’s all estimates, I’ve found it accurate on most aspects of the Chelyabinsk meteorite except the air blast. 100m impactor seems likely cause heavy local damage.

If you were right under it it would be catastrophic. But the damage decreases quickly the farther from the point of entry that you are.
