In 2024, a Quebec amateur astronomer scanning satellite images for a campsite noticed a 25-kilometre ring around Lake Marsal — a shape too deliberate to be coincidence. Geologists followed his lead, reached the site by floatplane in 2025, and confirmed what the land had quietly held for 390 million years: an impact crater from the Devonian age, marked by shatter cones that speak of cosmic violence frozen in stone. The discovery is a reminder that attention itself is a scientific instrument, and that the Earth still holds secrets visible to anyone willing to look.
