Camp Columbia, Former prison labor camp in Benton City, Washington, United States.
Camp Columbia was a federal prison facility on the north shore of the Yakima River with multiple Quonset buildings spread across about 25 acres. The installation processed thousands of tons of fruit through prisoner labor and supported food production during a critical time in American history.
Established in 1944, the camp held around 1,300 prisoners who worked in fruit orchards supporting the Hanford nuclear production effort during World War II. It was part of a broader U.S. strategy to mobilize agricultural labor while meeting both military and civilian needs at the same time.
The facility showed wartime adaptations that relied on minimum-security prisoners, including conscientious objectors, to keep agricultural production moving in the region. The work of those confined here became tied to local fruit and vegetable farming traditions and shaped the area's economic life.
The site sits on the banks of the Yakima River and is fairly accessible if you are in the Benton City area. It helps to gather local information before visiting, as the remains of the camp are scattered today and not always clearly marked for visitors.
Notably, the facility operated without security fences despite being a prison, relying instead on the surrounding geography as a natural boundary. This unusual security arrangement reflected the trust placed in a low-security prisoner population and detainees who were willing to work.
