This trigonometric station is part of the National Geodetic Survey's network of horizontal control points that establish the foundation for precise surveying and mapping across the United States. Located near Bellevue, Washington, this trig point serves as a reference for determining accurate positions and distances in the Puget Sound region. Trig stations of this type were traditionally established at elevated or prominent locations to facilitate line-of-sight observations between multiple points. Such monuments provide essential control for cadastral surveys, engineering projects, and geographic data collection. The NGS network remains fundamental to modern surveying practice, supporting both classical and contemporary positioning methods. Verification and documentation of existing benchmarks ensure continuity of the geodetic framework and enable surveyors to maintain consistency across projects. Professionals conducting work in this area should refer to official NGS records for complete monumentation details and current condition assessments.
