This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Triangulation stations serve as precise horizontal control points, historically established through intervisible sight lines to support large-scale geodetic surveys and subsequent mapping projects. Located at coordinates 21.45987°N, 158.16880°W in Hawaii, this benchmark contributes to regional geodetic infrastructure in the Pacific. Such control points remain valuable for verifying modern GPS/GNSS measurements, maintaining survey continuity, and establishing legal property boundaries. Documentation and periodic verification of these stations help preserve the integrity of the Nation's geodetic datum and support surveying professionals conducting detailed work across the islands. Elevation data for this station is not currently recorded in available documentation.
