Fodor's Review

Thanks to old mining waste, Butte has the dubious distinction as the location of the largest toxic-waste site in the country. Some underground copper mines were dug up in the 1950s, creating the Berkeley Open Pit Mine, which stretches 1½ by 1 mi, reaches 1,800 feet deep, and is filled with toxic water some 800 feet deep. A viewing platform allows you to look into the now-abandoned mammoth pit where more than 20 billion pounds of copper, 704 million ounces of silver, and

3 million ounces of gold were extracted from the Butte mining district.
