(Anaconda Smelter Stack) was the tallest masonry structure in the world and that the smelter-refining complex constituted the world's largest non-ferrous processing plant. In 1980, Atlantic Richfield Company closed the smelter, bringing an end to almost a century of mineral processing. While some aspects of the operation had been cleaned up under environmental laws, closing the smelter resulted in a large area contaminated with hazardous wastes. Since then, an operation for environmental cleanup was put into place by the federal Environmental Protection Agency and executed with the assistance of ARCO. The multimillion-dollar cleanup and redevelopment has resulted in the "Old Works" Golf Course, a championship 18-hole course designed by Jack Nicklaus. Anaconda joined with Deer County to form a consolidated city-county government in 1977. Part of Anaconda is included in the Butte-Anaconda Historic District.
