The Military during WWII in the Park

The Haleakalā Section of Hawai'i National Park was used by the military from 1941-1948. The summit of Haleakalā (Red Hill) was the site of various installations; the first, a fixed radar station associated with the Aircraft Warning Service system. The Army also built a base camp for personnel stationed at the Summit on a six-acre site near Pu'u Nianiau. The Puʻu Nianiau base camp was turned over to the NPS in 1946. Red Hill was returned to the NPS in 1948; however, the dilapidated military buildings and antennae were not removed until 1961.
