Mon, 23 Feb 2026 00:00:00 GMT

Seven thousand years before the first European set foot in North America, someone built a fire on a rocky outcrop along the southern shore of Lake Superior. When the stone cracked from the heat, they poured cold water over it, then pounded out the gleaming copper mass beneath with stone hammers and chisels. The Keweenaw Peninsula had been in the mining business for millennia before anyone thought to call it that. This narrow finger of Michigan's Upper Peninsula, jutting northeast into the largest freshwater lake on Earth, sits on a geological anomaly so rare that nothing else like it exists anywhere on the planet -- a billion-year-old volcanic rift that deposited the only economically recoverable deposits of 97-percent-pure native copper ever found.

Keweenaw Peninsula: Lake-Effect and Rocket Smoke

Mon, 23 Feb 2026 00:00:00 GMT

Lake Superior dominates the Keweenaw's climate with an authority that borders on tyranny. The peninsula receives enormous amounts of lake-effect snow -- the community of Delaware recorded a single-season record snowfall in 1979 -- and the higher elevations near the tip of the pen...
