Reports of a two ton boulder of pure copper lying in a river bank on the Keweenaw peninsula of the upper peninsula of Michigan were dismissed as tall tales, until proven by a geologist in 1840. The boulder wound up at the Smithsonian Natural History Museum, a huge mining boom rush erupted, and the closest port town was named after the geologist, Houghton. Most of the small mines failed, but eventually a large consolidated firm found and mined the largest pure copper lode in the world.

Technically the copper was “rediscovered” (or stolen) as the Native Americans here had been mining it for at least 7,000 years and traded it as far as Effigy Mounds, Hopewell, and other prehistoric sites around the country—so don’t accept the common misconception that Europeans introduced metal work to this continent. However, European immigrants did expand the mines here to an astounding scale. The deepest part of the Quincy Mine above is over 9,000 feet below ground, which is over 6 times deeper than the Empire State Building is high, with huge rooms left behind after the copper seam was excavated (see photo), and 92 levels mostly flooded after the mine closed in 1945 due to competition from western mines.

The huge equipment includes many rare and once record-breaking pieces of industrial machinery, and the Quincy Mine tour is fascinating and essential to understand miners’ lives. Be sure to get a big Cornish Pasty at Roys in Houghton. There are some museums and a visitor center in Calumet, including a magnificent old theater with lovely murals, but since most of those tours are only in the afternoon, it may be smarter to tour the mine in the morning. There are a couple dozen interesting sites on the Keweenaw peninsula, but for me the most haunting exhibit was the description of the Italian Hall disaster at Christmas in 1913.

While capitalists are allowed to organize freely under the law, labor was not. Thousands of copper miners went on strike, and the mine owners hired ruthless, violent strikebreakers. Someone—an anti-unionist according to eight witness who later testified to Congress—yelled ‘fire’ into a crowded Christmas party on the second floor of the Italian Hall in Calumet. There was no fire, but 59 children and 14 adults died. Woody Guthrie explained what happened below.

“The copper boss’ thugs stuck their heads in the door,
One of them yelled and he screamed, “there’s a fire”
A lady she hollered, “there’s no such a thing.
Keep on with your party, there’s no such thing.”

A few people rushed and it was only a few,
“It’s just the thugs and the scabs fooling you, “
A man grabbed his daughter and carried her down,
But the thugs held the door and he could not get out.

And then others followed, a hundred or more,
But most everybody remained on the floor,
The gun thugs they laughed at their murderous joke,
While the children were smothered on the stairs by the door.”
