While trying to find a suitable place for camping in an unknown part of Quebec, Canada, scientists came across something far more ancient than expected – a 25-km-wide impact crater that is estimated to be around 390 million years old.
The peculiar geological formation was spotted by an amateur astronomer Joël Lapointe in 2024 when he was studying satellite images of the Côte-Nord province. A giant circle near Lake Marsal caught his attention and raised a question: is it the leftover from a meteorite impact that happened long ago?
