"Glass Beach is a unique beach, not because nature made it that way, but because time and the pounding surf have corrected one of man's mistakes.
Beginning in 1949, the area around Glass Beach became a public dump. It is hard to imagine this happening today, but back then people dumped all kinds of refuse straight into the ocean, including old cars, and their household garbage, which of course included lots of glass.
By the early sixties, some attempts were made to control what was dumped, and dumping of any toxic items was banned. Finally in 1967, the North Coast Water Quality Board realized what a mistake it was and plans were begun for a new dump away from the ocean."
