National Park Service in Hawai'i

The American government and the American people were aware of the conflicts brewing in Europe, Asia, and Africa in the 1930s. Still hurting from the losses of World War I and in the grip of the Great Depression, there was little congressional or public interest in getting involved. In fact, there were efforts to keep America out of the conflict.

During the war, the United States government incarcerated many people in camps and prisons across the home front. This included enemy aliens, prisoners of war, Japanese Americans and Native Alaskans, and conscientious objectors. In Hawaii, the military imposed martial law. Elsewhere in the Greater United States, enemy forces incarcerated American civilians during and after the capture of American territories.

The Civilian Conservation Corps (CCC) Haleakala Crater Trails District is located in Haleakala Crater. The trail system was designed by NPS landscape architects, with construction and improvements made by CCC crews between 1930 and 1941. The trails blends in with the surrounding environment through the use of native materials.

Crater Rim Historic District, located in and around Kilauea Caldera in Hawaii Volcanoes National Park, is significant for associations with early park planning and the Civilian Conservation Corps. It is an example of the naturalistic landscape architecture style perpetuated by the NPS between the First and Second World Wars. The features that were designed to highlight and provide access to this unique volcanic landscape can still be experienced by visitors today.
