Looking for a Campsite, Found a Cosmic Catastrophe: How a Camper Discovered a 390-Million-Year-Old Meteorite Crater on Google Maps
Most people browse Google Maps hoping to find a scenic campsite with good shade, a fire pit, and minimal mosquitoes. French-Canadian amateur astronomer Joël Lapointe opened satellite view and accidentally discovered a 25-kilometer prehistoric apocalyptic ground zero.
While planning a quiet backcountry camping holiday in Quebec's rugged Côte-Nord region, Lapointe zoomed into satellite maps around Lake Marsal. Instead of standard Canadian wilderness, he noticed something oddly geometrical: a sweeping, curved ring of mountain ridges roughly 15 miles across, cupping a curious circular depression. Suspecting Mother Nature didn't draw giant circles with protractors by accident, Lapointe forwarded his coordinates to planetary geologists.
🏕️ From Holiday Scout to Planetary Investigator
What happens when your casual vacation scouting trips trigger an international scientific expedition:
- The Discovery: While panning around Côte-Nord lakes, Lapointe flagged a 25 km circular ring of hills that looked suspiciously un-glaciated.
- Calling in the Heavy Artillery: He emailed his satellite screenshots to Dr. Gordon Osinski, a world-renowned planetary geologist and meteorite impact specialist at Western University.
- The Bushplane Trek: In late 2025, Osinski and a team of geophysicists flew a floatplane into the remote, roadless Canadian taiga to inspect the bedrock in person.
Field expeditions to verify impact craters are notorious for debunking enthusiastic amateurs; ancient volcanic calderas and glacial sinkholes love masquerading as meteor craters. But when Osinski's team stepped onto the rocky shores around Lake Marsal, they struck geological gold: shatter cones and impact melt rock.
💥 The Smoking Gun: Shatter Cones & Impact Melt
In geology, shatter cones are the ultimate undeniable smoking gun of hyper-velocity cosmic violence:
- Cosmic Shockwaves: Shatter cones are delicate, horseshoe-shaped striations etched into bedrock that only form when shock pressures exceed 2 to 30 gigapascals—conditions produced exclusively by nuclear detonations or hypersonic meteorite impacts.
- 390-Million-Year Pedigree: Preliminary radiometric dating places the cosmic crash during the Devonian Period (around 390 million years ago), long before dinosaurs roamed the Earth and when primitive fish were just thinking about crawling onto land.
- Honorary Innu Name: In partnership with the local Ekuanitshit Innu Council, the structure was provisionally named Uhackatik, meaning "an area good for caribou hunting."
Only roughly 200 confirmed meteorite impact craters are known on Earth's surface, because hundreds of millions of years of plate tectonics, wind erosion, and glacial bulldozers usually grind them into dust. Finding a fresh 25-kilometer ring hiding in plain sight under satellite view is an extraordinary jackpot.
As for Joël Lapointe? He may or may not have found the coziest campsite in Quebec, but he definitely walked away with the ultimate campfire bragging right: discovering the scar of an ancient cosmic missile strike from the comfort of his living room laptop.
