All that remains of the Heart Mountain concentration camp, where the United States imprisoned over 14,000 Americans of Japanese descent between 1942 and 1945, is the camp’s hospital building. Over the course of a few months in 1942, the federal government transformed hundreds of acres in remote northwest Wyoming—near Yellowstone National Park—into the state’s third most populous city. The valley plain beneath Heart Mountain became one of ten “Relocation Centers,” the Orwellian name given to the World War II era camps in which over 100,000 people were imprisoned on the basis of their Japanese heritage. Back then, Heart Mountain was a bustling camp consisting of barracks, mess halls, toilet and laundry facilities, recreation spaces, workshops, schools, the hospital, a courthouse, administration buildings, nine guard towers, and a barbed-wire perimeter fence. This October, when I scanned the horizon for some sense of place or history, all I could make out was the original hospital building and snow-covered fields.
