As you may know, Canada is absolutely full of impact craters. In fact, of the 10 largest craters on Earth, Canada contains 5 of them - but it just might contain 6. In Northwestern Ontario lies North Caribou Lake- another 20 km wide reminder that Canada once had glaciers. Yet from a satellite view it appears to occupy a vast egg-shaped formation made obvious by the Eyapamikama Lake to the north and an unnamed river to the south. Continuing to look around the area will reveal more features appearing to make a circular shape around 52.59706 N 90.824734 W. In total, the crater appears to measure at least 50 kilometers wide, making it the 15th largest possible crater on Earth (not including uncomfirmed craters)
Unfortunately the crater is in the middle of nowhere, the nearest town to it is Pickle Lake, with a population of only 425.
I could of course try to report it to the Earth Impact Database but they require evidence of an impact crater versus a geologic dome or volcanic crater - shatter cones, shocked quartz, impact breccia, etc etc. All of this would require a visit to the crater, yet I have neither the money or the time to do this any time soon. So I ask, by the off-chance anyone lives near the crater, consider taking a trip there and look for any of the above mentioned features.
In the mean time, I'll be saving up to go there myself.
Either way, happy New Year!
