Kennecott's Bingham Canyon Mine

18 million tons of copper has been mined in the "Richest Hole on Earth" since 1906.
Of course, vast quantities of gold, silver and other material have been unearthed too. Notice how little the man is on the side of that equipment. Those 320 ton haulage trucks are HUGE. We went with Debbie and Doug again, watched a video, it was very interesting.
