The Bingham Canyon open-pit mine is the biggest hole dug by man anywhere in the world - about 2 1/2 miles long and nearly a mile deep, according to its owner, Kennecott Utah Copper. Miners have been digging copper, silver, and gold out of Bingham Canyon, just outside Salt Lake City, since 1906. These days huge trucks that cost up to $3 million each work around the clock, hauling about 450,000 tons of dirt out of the earth each day. More than 99% is waste. But by expending vast amounts of energy - the mine operates its own coal-fired power plant - Kennecott is able to extract an average of about 795 tons of copper, 12,000 troy ounces of silver, and 1,400 ounces of gold a day.
