But not every area of the county saw growth. The former mining towns related to Bingham Canyon were abandoned in the 1960s and 1970s to make way for expansion of the open-pit mine. The city of Bingham Canyon was completely torn down and swallowed up in the mine by 1972, and the dismantling of Lark in 1980 completed the process. The only remaining mining town in the county is Copperton, located southwest of West Jordan, with approximately 800 residents. Magna has workers who continue to be associated with the mine's smelting operations in Garfield and at Arthur Mill.
