This triangulation (trig) station is part of the National Geodetic Survey's network that established the foundational control framework for surveying and mapping across the United States. Located near Waipahu on the island of Oahu, Hawaii, this point serves as a monumented reference for horizontal positioning in the Hawaiian archipelago. Trig stations of this era provided precise geodetic control essential for subsequent surveys, cartography, and infrastructure development. The coordinates 21.47705°N, 158.03440°W place this benchmark within an established network of intervisible points used for triangulation methods. Verification and documentation of such control points remains valuable for surveyors conducting modern work, as these monuments often serve as tie-in references for GPS networks and contemporary survey operations. Proper archival of their locations and characteristics supports continuity in geodetic standards and accurate spatial reference systems.
