"We spent part of Labor Day watching the mucking and drilling competition in Park City, Utah. Park City is famous for its skiing, but the slopes sit atop the silver mines that were the foundations of the town’s economy for nearly one hundred years. Deep under the lifts and the town itself are some 1,200 miles of tunnels. There thousands of silver miners from around the world drilled, blasted, and hauled the silver ore out of the earth. Most of them died young, but the owners, including the father of William Randolph Hearst, made immense fortunes.". . .
