• Haleakalā National Park - HI
    Haleakala National Park is located on the island of Maui. "Between 1934 and 1941 the Civilian Conservation Corps (CCC) operated work camps at Haleakalā... Here at Haleakalā National Park the CCC was engaged in a variety of projects. CCC enrollees removed invasive plants and feral animals such as pigs and goats, constructed the Sliding Sands and Halemau'u trails, and built the backountry cabins and water tanks within Haleakalā crater. They also built many of the frontcountry structures still used by park employees and visitors today."   (https://www.nps.gov)
