Minidoka Internment National Monument was established in 2001 as the 385th unit of the National Park System to commemorate the hardships and sacrifices of Japanese Americans interned there during World War II. Also known as the 'Hunt Camp', the Minidoka Relocation Center was a 33,000-acre site with over 600 buildings and a total population of about 13,000 internees held from Washington, Oregon, and Alaska. It was in operation from August 1942 until October 1945. The Monument is located between the towns of Twin Falls and Jerome, Idaho in south central Idaho.
