Google Maps Canada Meteorite Discovery: How Quebec’s Uhackatik Crater Was Confirmed
The google maps canada meteorite discovery is the identification of Uhackatik, a previously unrecognised impact structure in Quebec’s remote Côte-Nord region. Amateur astronomer Joël Lapointe noticed its circular outline while using Google Maps to plan a camping trip; a later field expedition found geological evidence consistent with a hypervelocity impact roughly 390 million years ago.
The finding is significant because the satellite image did not prove the crater’s origin by itself. Scientists had to visit the site, inspect exposed rocks and collect samples. The current research abstract describes Uhackatik as a 25-kilometre-wide structure with well-preserved shatter cones and about 50 metres of impact-melt rock, while the full research has not yet appeared as a peer-reviewed paper. The official Meteoritical Society programme lists the team’s presentation for August 14, 2026.
What was discovered in Quebec?
Uhackatik is a large circular geological structure centred around Lake Marsal in the Côte-Nord region of Quebec. Reports describe the feature as approximately 25 kilometres across, or about 15.5 miles. Its ring-like topography was visible in satellite imagery, but the landscape is heavily eroded and does not resemble the fresh, bowl-shaped craters commonly shown in diagrams.
The site’s name was established through consultation with the Ekuanitshit Innu Council, whose traditional lands include the area. The Planetary Society’s account identifies Uhackatik as a crater formed by an impact about 390 million years ago and credits Google Earth imagery prepared by Gordon Osinski with showing the structure’s broad outline. The Planetary Society’s description of Uhackatik also provides the clearest public link between the original observation, the field investigation and the naming process.
How did Google Maps lead to the meteorite-crater discovery?
Lapointe was not searching satellite imagery as part of a formal geological survey. He was planning a route for a trip in Quebec when the circular depression caught his attention. According to the Smithsonian’s report on the discovery, he compared the feature with crater databases and then sent his suspicion to specialists after finding no obvious match.
The important point is that Google Maps functioned as a discovery and screening tool, not as a scientific confirmation instrument. A satellite view can reveal a circular pattern, drainage anomaly or unusual elevation change, but similar shapes can result from volcanism, glacial erosion, tectonic structures, mining or ordinary surface drainage. The platform helped a person identify a question that field geology could then test.
What evidence shows that Uhackatik is an impact crater?
The strongest evidence came from rocks rather than from the map. During the October 2025 expedition, researchers found shatter cones—cone-shaped structures with radiating fractures created by intense shock waves moving through rock. They also identified extensive impact-melt rock, material that formed when the impact’s pressure and heat melted part of the target terrain before it cooled and solidified.
The official conference abstract is more specific than early news reports: it says the structure contains well-preserved shatter cones and roughly 50 metres of impact-melt rocks. It also describes the origin as a hypervelocity impact. That primary conference record is the most direct public source for the reported dimensions and diagnostic evidence.
These observations matter because a circular outline alone is not unique to meteorite impacts. Shatter cones and impact melt are physical consequences of a very high-energy collision, so they provide a much stronger basis for interpretation than the shape seen in satellite imagery. The team is continuing to examine samples for additional microscopic and chemical signatures of shock.
How old is the crater?
The reported age is approximately 390 million years, placing the impact in the Devonian Period. That means the collision happened long before dinosaurs appeared and long before modern continents reached their present positions. The age is part of the research claim presented by the discovery team and repeated in recent independent coverage, rather than a date visible directly in Google Maps.
ABC News reported that the structure was confirmed by scientists in July 2026 and that the expedition took place in October 2025. Its account also notes that the crater is about 15.5 miles wide and was formed more than 100 million years before dinosaurs existed.
Readers should distinguish between the approximate age of the impact and the date of the discovery. The impact occurred hundreds of millions of years ago; Lapointe noticed the feature in the 2020s, and scientists investigated it in 2025. Those are separate events in the story.
Why did the crater remain unidentified for so long?
Ancient impact structures are difficult to recognise because erosion, glaciers, weathering and tectonic activity gradually destroy their original shapes. A crater that was once a clear depression can become a broad structural pattern in the bedrock, with lakes, ridges and valleys obscuring the initial impact form.
Remote location also matters. Uhackatik lies in a rugged part of northeastern Quebec, and the expedition team described the fieldwork as unusually demanding. A feature can be visible from space yet remain difficult to reach, map on the ground and sample safely. This is one reason why satellite imagery often produces hypotheses faster than geology can verify them.
The age of the structure increases both its scientific value and its uncertainty. Older craters preserve a longer record of Earth’s impact history, but they are also more likely to have lost diagnostic features. In Uhackatik’s case, the survival of shatter cones and impact melt appears to have provided unusually useful evidence.
Is the discovery already fully peer-reviewed?
Not yet, based on the information publicly available on July 26, 2026. The team’s findings are scheduled for presentation at the 88th Annual Meeting of the Meteoritical Society in Frankfurt, Germany, on August 14. The official programme gives the presentation title as “Uhackatik: A New 25-km-diameter ~390 Ma Impact Structure in Quebec, Canada” and identifies the work as a confirmation of hypervelocity impact origin.
A conference abstract is a primary research record, but it is not the same as a completed journal article that has passed peer review. The distinction is important when evaluating headlines that use words such as “confirmed.” In this case, “confirmed” reflects the researchers’ current interpretation and the evidence reported in the abstract; further publication may add detail, revise the age or refine the structure’s classification.
The conference’s official scientific-program page confirms that the 2026 meeting will present abstracts and research talks, while the detailed technical programme contains the Uhackatik entry. Until the study is published in full, the abstract and the researchers’ statements are the appropriate basis for reporting the result.
What does this mean for the use of Google Maps in science?
The discovery illustrates a practical pattern: public mapping tools can expose large-scale clues that experts might otherwise overlook. They are especially useful for scanning remote terrain, comparing circular landforms and identifying candidates for geological follow-up.
They do not replace fieldwork. A responsible workflow separates visual observation from scientific conclusion:
- Record the feature’s approximate location, scale and orientation.
- Compare satellite imagery with topographic and geological maps.
- Check established databases to see whether the structure is already known.
- Look for alternative explanations, including glacial, volcanic and tectonic processes.
- Submit the observation to a relevant research group or public database rather than presenting it as a confirmed crater.
Lapointe’s contribution was the initial observation and referral. The crater designation came only after specialists examined the terrain and rocks. That division of labour is a useful model for citizen science: a non-specialist can identify an anomaly, while trained researchers test its cause.
Can you view the Canadian meteorite crater on Google Maps?
You can look for the broad circular structure around Lake Marsal in Quebec’s Côte-Nord region using satellite imagery, but the map view should be treated as an orientation aid rather than a complete geological map. Imagery dates, zoom levels, terrain shading and map labels can change, and a screen view cannot show the rock evidence that supports the impact interpretation.
The public visual record is useful for understanding why Lapointe noticed the feature: the structure forms a large, roughly circular pattern that stands out against the surrounding terrain. The Planetary Society image page includes a Google Earth-based rendering of Uhackatik, while the scientific confirmation comes from field observations and sample analysis.
Do not assume that every circular lake or depression visible in Canada is a meteorite crater. A plausible candidate needs independent geological evidence, and even an apparently strong candidate may remain disputed until diagnostic rocks, geochemical signatures and reliable age constraints are available.
What to watch next
The next major milestone is the team’s presentation at the Meteoritical Society meeting in August 2026. More detailed results may follow through a peer-reviewed paper, including the sample methods, dating technique, microscopic shock evidence and how the crater fits into Canada’s known impact record.
For now, the practical conclusion is straightforward: Google Maps revealed the clue, but geology established the case. Uhackatik is a timely example of how open satellite imagery, public observation and specialist fieldwork can combine to uncover a major feature that remained unrecognised for hundreds of millions of years.
