The Old Works Golf Course is Montana's only Jack Nicklaus signature golf course open to the public. Rich in history the site was the original location for Anaconda's first copper smelter. After laying idle for nearly a century, it became a Super Fund clean-up site in 1983. In the late 80's the idea of reviving the Old Works site with a world class golf course became a dream of the Anaconda community and Arco. Now through exhaustive efforts to make the site safe, the Old Works Golf Course is a reality.

The Old Works features multiple tees, which allow players of all skill levels to play and enjoy this 18-hole course. Measuring from 5,300 yards to 7,700 yards the course is situated along Warm Springs Creek and the mining remnants against the hill sides. Among the mining relics that are predominant around the course none is more dramatic than the huge piles of black slag, a by-product of the copper smelting process. The slag is also utilized in the bunkers at Old Works, making for a dramatic contrast to the lush green of the course. The fairways are bordered by native grasses that have been reestablished to blend with the area's natural environment.
