What's Happening?
A 15-mile-wide pit discovered by amateur astronomer Joël Lapointe on Google Maps in 2024 has been confirmed as a 390 million-year-old meteor impact crater. The discovery was made in Quebec's Côte-Nord region, centered around Lake Marsal. Initial suspicions
about the pit's extraterrestrial origins were raised by French geophysicist Pierre Rochette, who noted the topography's suggestive nature. A team led by Gordon Osinski, a professor of planetary geology, conducted an on-site investigation in October 2025. They identified shatter cones and impact melt rock, both indicative of a meteor impact. The crater, now named Uhaachatik Crater, was confirmed after extensive testing of rock samples.
Why It's Important?
The confirmation of the Uhaachatik Crater adds to the limited number of known meteor impact sites on Earth, providing valuable insights into planetary geology and the history of meteor impacts. Such discoveries help scientists understand the effects of meteor impacts on Earth's geology, biology, and climate. The identification of this crater also highlights the potential for citizen scientists to contribute to significant scientific discoveries. The crater's confirmation underscores the importance of interdisciplinary collaboration in verifying and studying geological phenomena.
What's Next?
The research team plans to present their findings at the Annual Meeting of the Meteorological Society in Germany. Further analysis of the collected samples will continue, aiming to uncover more details about the impact event and its implications. The study of such craters can inform future research on planetary defense and the potential risks posed by asteroid impacts. Additionally, the collaboration with the Ekuanitshit Innu council in naming the crater reflects ongoing efforts to involve indigenous communities in scientific research.
