The Ancient Technology Found in an Ontario Copper Pit Exceeds Anything Its Tools Could Build

In 1847 a mine captain broke through a rock wall below Mamainse Point on the north shore of Lake Superior and found a chamber already worked out. The walls were cut straight, the floor level, and in one corner, on cedar cribbing, sat a four-ton mass of native copper with lever marks underneath it. Someone had tried to move it and never come back. This is the record of the ancient copper pits of Michipicoten Island, and the Ojibwe — Anishinaabe — account beside it. Two independent lines describe the same ground. One is institutional: the Geological Survey of Canada from 1842, the Ontario Bureau of Mines reports, a 1951 field geologist who measured pit walls too smooth for the tools found beside them, and a 1994 highway survey whose laser profile recorded cutting marks rather than percussion marks. The other is oral: what Alexander Henry was told in the 1770s about an island that withdraws from anyone approaching, the figure of Misshepezhieu at Agawa Rock, and one rule about that island's copper — it is not taken. Neither proves the other. But they describe the same gap. The institutional map ends where the ancient workings begin. The oral record begins where the archive ends. Who do you believe the Anishinaabe were remembering when they said that copper is not taken? Leave it in the comments. This documentary examines historical records, archaeological research, and Indigenous oral traditions. It presents documented findings alongside long-standing questions that remain open. Where accounts differ, both are presented. Nothing here is offered as a settled conclusion.
