of former inmates left Heart Mountain on November 10, 1945. Preservation and remembrance After Heart Mountain closed, most of the land, barracks and agricultural equipment were sold to farmers and former servicemen, who established homesteads on and around the camp site. The Heart Mountain Irrigation Project continued after the war, and much of the camp's surrounding acreage was tilled for irrigation agriculture. Remnants of the hospital complex (including foundations and 3 buildings), a Heart Mountain High School storage shed, a root cellar, the Honor Roll World War II Memorial and a portion of a remodeled barrack are the only buildings still standing today. The Heart Mountain Wyoming Foundation, established in 1996, has worked to preserve and memorialize the site and events, educate the general public about the Japanese American incarceration, and support research about the incarceration so that future generations can understand the lessons of the Japanese American incarceration experience. The Heart Mountain Wyoming Foundation is overseen by a 16-member Board of Directors and is led by the Chair, Shirley Ann Higuchi, a descendant of former internees. The board also includes former internees, scholars, and other professionals working on the local and national level. The Heart Mountain Wyoming Foundation gained National Historic Landmark status for the site in 2007 and on August 20, 2011, opened the Heart Mountain Interpretive Center. The Center features a permanent exhibit that provides an overview of the history of the wartime incarceration of Japanese Americans and the background of anti-Asian prejudice in America that led to it. Along with additional rotating exhibits, these photographs, artifacts and oral histories explore the incarceration experience, constitutional and civil rights issues, and the broader issues of race and social justice in America. Visitors can also participate in a walking tour of the site and its remaining structures. Former U.S. Secretary of Transportation Norman Y. Mineta and retired U.S. Senator Alan K. Simpson, who met as Boy Scouts on opposite sides of the barbed wire fence surrounding the Heart Mountain compound, act as Honorary Advisors to the Foundation. The Foundation hosts an annual pilgrimage at Heart Mountain, the first of which coincided with the Interpretive Center's 2011 opening. Terminology Since the end of World War II, there has been debate over the terminology used to refer to Heart Mountain and the other camps in which Japanese Americans were incarcerated by the United States Government during the war.
