Amache National Historic Site in southeastern Colorado is officially America’s newest national park, the National Park Service announced Thursday. Amache, located one mile outside of Granada, was one of 10 incarceration sites used to detain thousands of Japanese-Americans during World War II. The town of Granada acquired and donated the land needed to establish the site as a national park.
