Mankind’s largest excavation

The Colorado River spent 6 million years carving the Grand Canyon. It’s taken Utahans only a century to dig Kennecott’s Bingham Canyon Mine. Ok, so the Grand Canyon gets as deep as 6,000 feet and Bingham only reaches a bit past three-quarters of a mile. But consider this: The pit you see here used to be a mountain, which tacks on at least an extra 1,000 feet. We’re gaining on nature, and quickly.
In the latest issue of VIA magazine I’ve got a story on the open pit copper mine, which is the largest man-made excavation on Earth. Everything is oversize here, from the fleet of 80 haulage trucks taller than two-story houses and costing $2.8 million a piece to the 82 million gallons of water sprayed annually for dust control. And the mine runs 24 hours a day, 365 days a year. Sound like a monumental waste? Take a look around you before you wish it closed—everything from fridge to phone works thanks to copper. Come to think of it, the story of copper mining, accelerating from the first urban electrification projects to today’s massive resource extractions, is the story of modern America. Perhaps that’s why this hole is a National Historic Landmark.
For more crazy details on just how big this operation is and to learn how it is we can turn a ton of rock into 13 pounds of copper sheeting, watch this video. Spoiler alert: it involves a five-mile conveyor belt.
I’m spending most of my time working as a contract editor at VIA these days, so my freelance writing has slowed down a bit and I haven’t had as much to report here. I’m enjoying seeing the other side of the writing game, though, and it’s giving me the opportunity to go after breathtaking travel destinations like this one.
