Montana has a rich history of resource extraction. The hill in Butte, MT was originally one of the most prosperous sources of copper as the electrification of the US started and WWII demanded this new technology. In 1920, this town (which in 2023 had about 40,000 people) held up to 100,000 people all working around the resource extraction biz until things became harder and harder to extract. Soon, “The Richest Hill” turned into an open pit mine, then a superfund site which kills any bird that lands in the pit’s heavy metal water and now a tourist attraction.
