Butte, Montana is a mile high and a mile deep. The elevation is about a mile, and the extensive copper mines below the city run a mile underground. This episode is about those mines.
The man who speaks to you tonight is Lincoln, and he knows all about the depths below Butte. He's been down here before. One time he explored and came across a deep chasm he can never forget, and now it's time for you to hear what he saw there.
Some places there's just hot, heavy darkness. And silence. Like a grave.
