The mines were in Butte and the chief problem there is the Berkeley Pit. https://en.wikipedia.org/wiki/Berkeley_Pit Prior to the open pit mine the hill is riddled with traditional hard rock mines. When they were active pumps kept the ground water in control. The pumps were turned off in '82 and the pit started to fill. The ores were smelted in Anaconda. https://en.wikipedia.org/wiki/Anaconda_Smelter_Stack They realized the problem and the stack was an attempt to get the fumes out of the valley. It succeeded in that but they also had to buy a lot of land downwind. Even today not much grows there and the few trees are deformed. Anaconda took a novel approach and built a golf course on the tailings. https://nicklausdesign.com/course/oldworks/ There still are acres of uncovered tailings. If you take the hiking traill around the course you get to see the before state. Then there was the Milltown Dam. There was a lot of foot dragging and finger pointing but in '96 an exceptionally snowy winter formed ice floes and the dam was in danger of failing. That got peoples' attention. It was a long process but the sediments were sent back to Anaconda where they came from and the dam was removed. When you've got lemons, make a state park. https://fwp.mt.gov/stateparks/milltown The web site is a bit dated. The dam had acted to stabilize a rock face on the south side where the overlook is. A couple of years ago they decided it was unstable and closed it off. The old Milwaukee rail line has been converted to a bike path but Tunnel 26 1/2 passes under the outlook and the state isn't going to take the liability for that. There was also a plan to use an old bridge to cross the river where the rail bridge was and connect the north and south parts of the park but that's held up with some land deal. I often hike the trail up and over the ridge and down to the floodplain on the other side but it would be a difficult bike ride.
