A camper’s intuition on Google Maps led researchers to confirm a 15-mile-wide meteor crater in Quebec’s Côte-Nord region. Fieldwork revealed shatter cones and impact melt rock, dating the crater to about 390 million years ago, making it one of the larger known craters worldwide (with roughly 200 total known crater sites and 31 in Canada).
An amateur using Google Maps spotted a pit in Quebec’s Côte-Nord that turned out to be a 390-million-year-old meteor crater named Uhackatik, about 25 km across. A four-person team confirmed the site in 2025 after a rugged field expedition, finding impact melt rock and shatter cones as evidence. The discovery ranks among the larger craters identified in recent years and will be presented at the Meteoritical Society congress in Germany.
