Heart Mountain Relocation Center

The Heart Mountain War Relocation Center, named after nearby Heart Mountain and located midway between the northwest Wyoming towns of Cody and Powell, was one of ten concentration camps used for the internment of Japanese Americans evicted during World War II from their local communities (including their homes, businesses, and college residencies) in the West Coast Exclusion Zone by the executive order of President Franklin Roosevelt (after the bombing of Pearl Harbor in December 1941, upon the recommendation of Lieutenant General John L. DeWitt). This site was managed before the war by the federal Bureau of Reclamation as the would-be site of a major irrigation project.
