What company owns a hydroelectric, concrete gravity dam; located on the Columbia River, between the Yakima Firing Range and a mostly decommissioned nuclear production complex operated by the United States federal government on the Columbia River in the U.S. state of Washington?
Hanford Site The Hanford Site is a mostly decommissioned nuclear production complex operated by the United States federal government on the Columbia River in the U.S. state of Washington. The site has been known by many names, including: Hanford Project, Hanford Works, Hanford Engineer Works and Hanford Nuclear Reservation. Established in 1943 as part of the Manhattan Project in Hanford, south-central Washington, the site was home to the B Reactor, the first full-scale plutonium production reactor in the world. Plutonium manufactured at the site was used in the first nuclear bomb, tested at the Trinity site, and in Fat Man, the bomb detonated over Nagasaki, Japan.
Confluence Project The Confluence Project is a series of outdoor installations and interpretive artworks located in public parks along the Columbia River and its tributaries in the U.S. states of Washington and Oregon. Each art installation explores the confluence of history, culture and ecology of the Columbia River system. The project draws on the region's history, including Native American traditional stories and entries from the Lewis and Clark Expedition journals, to "evoke a landscape and a way of life submerged in time and memory." The project reaches from the mouth of the Columbia River to Hells Canyon.
