On the banks of the Pacific Northwest's greatest river lies the Hanford nuclear reservation, an industrial site that appears to be at odds with the surrounding vineyards and desert. The 586-square mile compound on the Columbia in eastern Washington is known both for its origins as part of the Manhattan Project, which made the first atomic bombs, and for the monumental effort now under way to clean up forty-five years' of waste from manufacturing plutonium for the U.S. nuclear weapons complex. Hanford routinely makes the news, as scientists, litigants, administrators, and politicians argue over its past and its future.
