Amateur Astronomer Uncovers Massive 390-Million-Year-Old Meteorite Crater via Google Maps

DNI SUMMARY — KEY POINTS

• An amateur astronomer discovered a massive 390-million-year-old impact crater while using Google Maps to plan a routine camping trip in Quebec.
• The newly identified site, named Uhackatik, spans 25 kilometres in diameter and was confirmed by a scientific team led by Gordon Osinski.
• Experts confirmed the site's authenticity by locating rare shatter cones and impact melt rocks that only form during extreme meteorite collisions.
• The discovery is considered a rare and significant geological finding as there are only about 200 confirmed impact craters documented worldwide today.
• Researchers plan to present their comprehensive findings and laboratory analysis of the collected geological samples at the upcoming Meteoritical Society congress.

An unexpected geological discovery has emerged from the depths of the Canadian wilderness, where an amateur astronomer identified a massive 390-million-year-old meteorite crater while browsing Google Maps. What began as a simple exercise in planning a personal camping excursion transformed into a major scientific revelation. Located in the rugged terrain of Quebec, the site had remained hidden from geological record until the digital observation caught the eye of an astute observer. This event underscores how accessible satellite technology is now bridging the gap between casual exploration and serious planetary science.

The Scale of Discovery

The formation, now officially designated as the Uhackatik crater, measures a staggering 25 kilometres in diameter. Its presence was entirely absent from existing global databases, leading researchers to classify it as a significant find in the study of Earth's ancient history. The sheer scale of the depression suggested a high-energy impact event from the distant past, yet it remained tucked away in a remote region. It serves as a reminder that large-scale geographical features can still escape human detection even in an era of constant global mapping.

Scientific validation required a challenging five-day field expedition conducted by a four-person team in 2025. Led by the renowned planetary geologist Gordon Osinski, the group navigated dense, overgrown, and unforgiving terrain to reach the site. Osinski, a professor at Western University, noted that this particular mission was among the most difficult he had ever undertaken across his career on six continents. The team arrived equipped to confirm the origin of the circular landform that had piqued curiosity through digital satellite imagery.

Field Expedition and Challenges

Physical evidence gathered on-site provided the definitive proof required to verify the crater's extraterrestrial origins. The presence of shatter cones—rare, conical-shaped rock fractures created only by the shockwaves of massive meteorite impacts—was confirmed immediately upon examination. Furthermore, the team located significant amounts of impact melt rocks. These unique geological specimens form exclusively when solid bedrock is liquefied by the intense, furnace-like temperatures generated during the kinetic energy release of a catastrophic celestial collision, leaving behind a permanent record of the strike.

The discovery process highlights the vital role of public engagement in the modern scientific landscape. Joël Lapointe, the amateur astronomer who first spotted the anomaly, reached out to experts after finding no documentation of the site in public databases. While specialists often receive numerous false alarms from the public, this instance stood out as an exceptional anomaly. It proved that despite modern advancements in algorithmic analysis, the human eye remains a uniquely capable tool for identifying subtle, yet historically significant, patterns within the chaotic topography of the natural world.

The Scientific Validation Process

Looking ahead, the findings from this expedition are destined for the global stage at the upcoming annual congress of the Meteoritical Society held in Germany. Researchers are currently engaged in detailed laboratory analysis of the samples retrieved from the site, with work being shared between labs in France and Ontario. This collaborative effort is aimed at reconstructing the specifics of the impact event, which occurred millions of years before humans inhabited the planet, offering a window into Earth's turbulent geological evolution and its long-standing relationship with near-Earth objects.

The confirmation of the Uhackatik site adds to a very short list of verified impact craters, currently numbering around 200 globally. Scientists are optimistic that this discovery will encourage a renewed focus on examining remote, inaccessible landscapes through high-resolution satellite imagery. By applying the same observational techniques that led to this breakthrough, researchers hope to uncover other buried impact sites that remain hidden beneath the earth's surface. Each new discovery helps to refine our understanding of the frequency and scale of cosmic threats throughout our planet's history.

Citizen Science and Future

This discovery serves as a powerful testament to the value of open-access mapping platforms in fostering citizen science. While tools like Google Maps are primarily used for navigation, they have inadvertently become essential resources for the global scientific community. As satellite imagery continues to improve in clarity and coverage, it is likely that more ancient geological secrets will be revealed by everyday users. The story of the Uhackatik crater confirms that the most profound discoveries often happen when curiosity is allowed to wander far beyond the familiar, well-mapped paths.
