About twenty-nine people a year died recreating on mine property over the decade ending 2008, mostly drowning in flooded pits, falling down hidden shafts, or breathing air that cannot sustain life. Nearly half were fifteen to twenty-five. The episode explains the hazards, what closure takes, and why coal's fee-funded cleanup received $11.3 billion while hardrock gets about five million dollars a year.
