Exxon Valdez oil spill – in pictures
On 24 March, 1989 an oil tanker ran aground in the pristine waters of Prince William Sound in the Gulf of Alaska, dumping 11 million gallons of crude oil. The spillage affected 11,000 square miles of sea, killing thousands of marine mammals and sea birds, and had a devastating impact across the 1,300-mile of shoreline. Twenty-five years on it remains one of the worst environmental disasters of all time
