Poston War Relocation Center

The Poston Internment Camp, located in Yuma County (now in La Paz County) in southwestern Arizona, was the largest (in terms of area) of the 10 American concentration camps operated by the War Relocation Authority during World War II. The site was composed of three separate camps arranged in a chain from north to south, three miles from each other. Internees named the camps Roasten, Toastin, and Dustin, based on their desert locations.
