Long before Stonehenge and the Pyramids were built, an industry was flourishing in North America near the Lake Superior shores. Copper was being mined. No one knows for sure who these ancient miners were, but thousands of mine pits and tools were left behind as evidence of their mysterious past. This documentary takes us back in time to explore this fascinating story.
