"Michigan Copper: The Untold Story" is the final book by C. Fred Rydholm, author of the classic two-volume work "Superior Heartland: A Backwoods History." In "Michigan Copper", Rydholm turns his attention to the mining and mineral heritage of Michigan's Upper Peninsula, presenting his theory that the natural native copper endemic to Isle Royale and the Keweenaw Peninsula was a focal point of contact and trade in the ancient world. Rydholm's ideas are interwoven with a personal meditation on his lifelong fascination with native copper.
