The Hanford Nuclear Reservation is a mammoth, 586-square-mile chunk of desert earth in southeast Washington state. It became a secret site for refining the plutonium needed for nuclear weapons during WWII. Native American tribes and settlers were evicted off their traditional riverside villages and ripening farms to make way for the secret government mission. Workers turned cutting-edge science into factory production, churning out plutonium buttons right through the Cold War. After refining two-thirds of all the United States’ weaponized plutonium, Hanford is a boneyard of some of the earth’s nastiest chemicals and radioactive waste. Much of the cleanup is on a scale that twists the mind -- like the more than $12-billion Waste Treatment Plant being built now amid the sand and sagebrush.
