Stretching from the infamous Berkeley Pit at Butte to the former Milltown Dam site outside Missoula, the Clark Fork Superfund area is one of the largest in the country. An amalgamation of four different superfund sites, Butte/Silver Bow Creek, Montana Pole, the Anaconda Smelter, and the Milltown Reservoir, it runs along 140 contiguous miles of the Clark Fork River.
Leaving before sunrise, Thursday's Superfund Tour visited each of the major superfund sites along the river before ending back at Missoula later in the day. Each site offered a unique glimpse of the U.S. Environmental Protection Agency in action, working to remedy and restore lands degraded through the callous mineral extraction of copper kings.
