The Duty Station is: Kaloko-Honokōhau National Historical Park (U.S. National Park Service) Duties: Lifting, carrying, and handing tools and equipment to the journey-level employee; Helping to mix soils, water, and amendments according to prescribed instructions; Helping to spread mortar as directed; digging trenches or holes for the construction of masonry structures; Cleaning masonry tools and equipment; keeping work areas clean and orderly; Maintaining masonry work logs. The spirit of Kaloko-Honokohau was its life, the life that flowed in its land and the water that washed upon its shore. Like Hawaiians who found its presence elsewhere, the people of Kaloko-Honokohau let the spirit become part of their existence. They lived in such perfect harmony with it that they became a singular, total, and inseparable environment. From "The spirit of Kaloko-Honokohau"-1974 To survive in a hot and arid environment the native Hawaiians (kanaka maoli) used ancient fishing skills, including the building of fishponds, and the knowledge of the location of precious fresh water (wai) that flows into the many brackish pools throughout the park. The spirit of the people (poe) and the knowledge of the elders (kupuna) created a tradition of respect and reverence for this area. The island of Hawaii is subject to high concentrations of volcanic fumes (VOG), especially sulfur dioxide gasses and fine particulates. The fumes are known to be hazardous to an unborn fetus, and persons with heart and respiratory problems. The coastline primarily experiences VOG conditions throughout the year, and occasionally eastern Hawaii Island and other Hawaiian islands. Long-term effects on normal healthy persons are unknown.
