Beneath Ontario Lies A Lost World Older Than The Pyramids

Thirty-seven metres under Lake Huron, within sight of an Ontario beach, two lines of placed stones mark where caribou hunters waited for the herds about 9,000 years ago. A sand pit beside Ottawa's airport gave up the skeleton of a beluga whale from a sea that no longer exists. And divers brought two flakes of volcanic glass up from that lake floor, traced to a source in Oregon more than 4,000 kilometres away. What's beneath YOUR town? Personalized 15-page report — the rock, the name, the vanished places, your town's oldest map → https://hiddenprovinces.com One cause sits under every town in Ontario: the ice pressed the land down, and the land is still rising. It tilted Toronto's Lake Iroquois beach, so Davenport Road follows a shoreline and Casa Loma sits on the lip of a vanished lake. It let the Champlain Sea into the Ottawa Valley, with belugas, bowheads and walrus, and left behind the Leda clay that swallowed the empty village of Lemieux in 1993. It stranded the camps of Ontario's first people at Parkhill and the Fisher site, kept a quartzite quarry on Manitoulin Island in use for more than 9,000 years at Sheguiandah, and drowned the oldest sites of Rice Lake. Then it emptied the Huron basin into Lake Stanley and opened a dry causeway from Point Clark to Michigan: the Alpena Amberley Ridge, where Drop 45 still holds a stone hunting lane, three blinds and the chips of a resharpened spear. The same water that drowned it is the reason it survived.

Where reconstructions disagree, on the depth of Lake Stanley and the age of Sheguiandah, the narration says so. Subscribe to The Hidden Provinces — beneath the map.
