Geological activity gouged some crazy deep holes and dumped everything on top. Basically the entire upper peninsula was scooped out of lake Superior, flipped over and dumped on the ground, which is why there’s a bunch of metal everywhere up there.
Also some of the oldest exposed stone on the planet. Nothing too useful about it beyond “my, that’s a very old stone”, but it’s a vaguely fun fact.

That reminds me, I definitely need to track down some Mohawkite jewelry.
Sure, it’s technically toxic, but fashion always comes at a price.
