The tanker Exxon Valdez struck Bligh Reef in Prince William Sound, Alaska on March 24, 1989, releasing part of its 55 million gallon cargo of crude oil. Estimates of the total quantity of oil released range from ten to more than thirty million gallons. Whatever the quantity of oil, extensive damage resulted, including the collapse of the local fishery. Cleanup and other costs ran well into the billions. The ship underwent repairs and sailed under various names before being relegated to the scrapyard in 2012.
