Between Shoshone and Twin Falls, the potato-growing Snake River plains hold a surprising remnant of a moment in time many Americans would just as soon forget: the forcible arrest and deportation of 110,000 Americans of Japanese descent during the early 1940s. Moved from their homes in California, Washington, and Oregon—but not Hawaii, where they were a key segment of the workforce—entire families were uprooted and relocated to desolate, middle-of-nowhere places where they were made to live in makeshift shacks. Here at Minidoka Internment National Monument, 17 miles northeast of Twin Falls, more than 13,000 American citizens were held as prisoners between 1942 and the end of World War II three years later. The 73-acre site preserves a handful of buildings, including the guard house, but it’s the isolation that endures most. The site has no services, and can be hard to reach; head east from US-93 along Hwy-25 for 9.5 miles, then north along Hunt Road for another 2.5 miles. (The visitors center is in Hagerman, 20 miles away.)
