When industrialist John D. Rockefeller visited the new open-pit mining operation of his competitor, Daniel J. Guggenheim, in Bingham Canyon, Utah, in 1910, he declared with genuine envy and admiration,“it's the greatest industrial sight in the whole world.” What most impressed Rockefeller were the massive steam shovels that had revolutionized the process of copper extraction by enabling firms to mine and smelt tons of previously worthless low-grade copper ore. Equally impressive was the fact that, where skilled American miners had very recently toiled underground in search of rich veins of copper, unskilled immigrants now worked aboveground, loading tons of newly blasted copper ore onto train cars. Rockefeller was not alone in expressing wonder at this new man-made marvel. Hundreds of sight-seeing tourists also traveled to the mine by train each week to experience the thrill of industrial America's newfound ability to move mountains. Like Rockefeller, they saw nothing but progress and modernity in the great open-pit mine.
