Berkeley Pit

Why anyone would want to go swimming in a crater that was once a copper mine is beyond us. But creepy may also seem like beauty to others, and this water-filled pit fits the bill.

The gaping hole is now full of acidic water, and toxic sludge is in the bottom as well. We wonder what resilient life can flourish in there when chemicals are swirling in. The murky concoction belongs in a laboratory and not in a water-filled depression. Flavored with arsenic, copper, sulfuric acid, and zinc, to name a few, this one of a kind cocktail is not for swimming in or drinking.
