This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the foundational control points for surveying and mapping activities throughout the United States. Trigonometric stations like this one serve as precise horizontal reference points for geodetic work, enabling surveyors to conduct accurate measurements and coordinate determinations across projects both large and small. Located at coordinates 21.49164° N, 158.18967° W in Hawaii, this benchmark contributes to the broader NGS control network that supports surveying, engineering, and mapping efforts. The elevation data for this point remains unrecorded in available documentation. Verification and documentation of such geodetic reference points remain valuable for the surveying community, as these stations provide critical horizontal control for subsequent local surveys and construction projects. Proper maintenance and periodic re-observation of these markers help ensure the integrity of the nation's geodetic infrastructure.
