This book records the history of the Heart Mountain Relocation Center beginning on December 7, 1941, with the bombing of Pearl Harbor to April 22, 1953, when the Heart Mountain Post Office closed because nobody lived there anymore. The Center, located between the towns of Cody and Powell in northern Wyoming, was built in just 60 days to imprison 11,000 persons of Japanese ancestry living along the West Coast during WWII. This is the record of who built the incarceration site, where the blueprints came from, how its infrastructure turned out the way it did, who managed it, how the prisoners completed its construction with their own labor, what life was like living in such a place, and what happened to the camp after the war was over.
