Hudson Bay Is Hiding Something Nobody Talks About

Hudson Bay once sat under a glacier two miles thick, a weight so immense that the ground still has not finished rising back up, and standing on its shore you would actually weigh a tiny bit less than almost anywhere else on the continent. This countdown covers an inland sea boxed entirely inside Canada, nearly 470,000 square miles yet averaging only 330 feet deep, freezing solid every winter and melting every summer, home to 3,000 beluga whales crowding the Churchill River and polar bears fasting for months near Churchill, Manitoba, plus the mutiny that left explorer Henry Hudson adrift in 1611, the Hudson's Bay Company's 1670 royal charter over a third of a continent, and satellite data from 2007 revealing a measurable dip in Earth's own gravity. If you think you know this bay, the strangest fact about it is still something scientists cannot fully explain, even with satellites watching from orbit, so stick around to the very end. 🔔 Subscribe and turn on notifications so you never miss a story like this one.
