The largest open pit copper mine in the world is Bingham Canyon Mine in the Oquirrh Mountains by Salt Lake City, Utah. Now called Kennecott Copper Mine, the mine has been in existence for over 150 years. It produces 300,000 tons of copper per year, providing 13% of the US copper needs and 33% of the valley’s pollution.

The Bingham Cuff is a knitted cuff that is copper leafed. The cuff remains pliable and soft and gains a rich, crackly patina over the years.
