Thousands of Montana snow geese die after landing in toxic mine pit.
Witnesses said the pit looked like “700 acres of white birds.”

This was no ordinary pond, however. It was the 700-acre Berkeley Pit, a former mine now submerged in water as acidic as distilled vinegar. From 1955 until operations ceased in 1982, miners extracted nearly 300 million tons of copper ore from the pit. They left behind an immense crevasse, which filled with water 900 feet deep [175 billion liters.] Concentrated within the floodwater are arsenic, cadmium, cobalt, copper, iron, zinc and other inorganic compounds.
