"Twenty-five years ago on March 24, the oil tanker Exxon Valdez slammed into Bligh Reef and spilled more than 11 million gallons of crude oil into the cold, clear waters of Alaska's Prince William Sound — one of the 'last best places' on Earth. The oil charged through Prince William Sound and out into the Gulf of Alaska, damaging more than 1,300 miles of some of the most remote, wild shoreline in this country. This happened 25 years ago, so we might note the anniversary as we do any other historical event. That, however, would imply that the oil spill is over. It's not, and likely never will be."
