The Most Toxic Lake In The World

Berkeley Pit is an open pit copper mine located in the Butte, Montana, United States. Mine was opened in 1955 and operated by the Anaconda Copper and later by the Atlantic Richfield. It is filled to a depth of about 900 feet (270m) with water in it heavily acidic with 2.5 pH level. It is laden with heavy metals and very dangerous chemicals that leach from the rock, including arsenic, cadmium, cink and sulfuric acid. The pit and its water present a serious environmental problem. Currently it is a tourist attraction and for 2$ fee you can go on the viewing platform and enjoy the toxic view.
