Photographer’s Note

Also known as the Kennecott Mine.

Dominating the landscape of the Oquirrh Mountains southwest of Salt Lake City, this open pit mine is the largest man-made excavation. The mine comes in at over 3/4 miles in depth and 2.5 miles wide. Mining in the area started in the 1850's but it wasn't until the early 1900's that the mine really started producing, when it was shown that the low grade ore could be profitable. Over its life the mine is one of the largest producers of copper, more than any other mine in the United States. It also produces gold and silver, which are impurities removed from the copper. These metals have combined to make the resources mined of more value than the Comstock Lode, Klondike, & California gold rush area combined.

As for the photo, this is a 1x4 stitch to get a feeling for the size of the mine. I had to work quick so that the trucks wouldn't cause problems with the stitch. The trucks, which run pretty much continuously are quite large, with the tires being about 15 feet in diameter and costing around $20,000 each. Each truck carries over 250 tons of material on each trip.
