Hanford Nuclear Reservation

The now idled nuclear reactor at the Hanford Nuclear Reservation sits on the bank of the Columbia River near Richland, Wash., on Aug. 5, 1997. This area of the river, known as the Hanford Reach, is the last free-flowing stretch of the Columbia River. A national conservation group names the Hanford Reach of the Columbia River in Washington state the most endangered river in North America and urged the Clinton administration to create a 90,000-acre refuge to protect it.
