Ontario's Craters Are Hiding Something Nobody Talks About

In April 1972, standing at the rim of North Ray crater on the Moon, John Young picked up a rock and said it looked like a Sudbury breccia. NASA had sent him to Sudbury, Ontario, to learn what an impact crater looks like. For most of a century nobody knew what had made the biggest crater in Ontario, and since 2020 three of the province's craters have been dated to the same narrow window, when, by one new theory, the Earth wore a ring like Saturn's.

Personalized 15-page report — the rock, the name, the vanished places, your town's oldest map → https://hiddenprovinces.com This documentary follows Ontario's five confirmed impact craters. Sudbury: Albert Salter's swinging compass in 1856, the railway cut of 1883, the nickel that armoured the world's navies, the Deutschland submarine scandal of 1916, Robert Dietz and the shatter cones of 1964, the Apollo 16 and 17 astronauts in 1971 and 1972, SNOLAB two kilometres down in Creighton Mine, the Robinson Huron Treaty and the Superstack coming down in 2026. Brent, found on an aerial photograph in 1951 and the keystone of Canada's crater hunt. Holleford, a crater under a farm near Kingston. Wanapitei, a crater that is now a lake. The Slate Islands in Lake Superior, with the largest shatter cones on Earth and a caribou herd that nearly vanished. Then the new crater in Quebec that an amateur spotted on Google Maps, and the Monash University study that places Brent, the Slate Islands and Holleford in the same bombardment, 466 million years ago, under a ring around the Earth. Sources include the Earth Impact Database at the University of New Brunswick, Western University's impact crater database, the Geological Survey of Canada, the Ontario Geological Survey, Dietz (1964) and French (1967), the Apollo 16 lunar surface journal, Science North, the Lunar and Planetary Institute, the Supreme Court of Canada's 2024 Robinson treaties ruling, Tomkins et al. in Earth and Planetary Science Letters (2024), and the 2025 field confirmation of the Uhackatik crater. Where scientists disagree, on Sudbury's size, what hit it, and whether the ring existed, the narration says so. Subscribe to The Hidden Provinces — beneath the map.
