The Tule Lake Unit of the World War II Valor in the Pacific National Monument in Modoc and Siskiyou counties in California, consists primarily of the site of the Tule Lake War Relocation Center, one of ten concentration camps constructed in 1942 by the United States government to incarcerate Japanese Americans forcibly removed from their homes on the West Coast. They totaled nearly 120,000 people, two-thirds of whom were United States citizens.
