A silver camp that turned out to sit on the largest copper deposit ever found, just as the world started wiring itself for electricity. Ten thousand miles of tunnel run under the town, which drew Irish, Cornish, Finnish and Serbian miners and had one of the strongest union cultures in America.
That was 1 of the hidden places.
