Summary
A geology team verified that a remote Quebec formation first flagged on Google Maps is a 15-mile-wide meteor crater dating back 390 million years.
Joël Lapointe spotted the circular feature while planning a 2024 camping trip, prompting researchers to mount a difficult expedition into the rugged Côte-Nord region.
shatter cones found on the second day and "spectacular" impact-melt rock provided the key evidence that the site was formed by an asteroid strike.
Only about 200 meteor craters are known worldwide; Canada has 31 confirmed sites, making the Quebec find one of the larger recent additions.
