Historical & Ecological Origin

The Berkley Pit was an active open-pit copper mine from 1955 to 1982, operated by the Anaconda Company. It is a man-made excavation resulting from extensive mineral extraction. The pit now contains a permanent body of acidic water, a result of groundwater inflow and the oxidation of sulfide minerals exposed during mining operations.

Facts & Legends

The water in the Berkley Pit is highly acidic, with a pH typically between 2.5 and 3.0, comparable to lemon juice. It contains elevated levels of copper, arsenic, and other heavy metals.
