This triangulation station is part of the National Geodetic Survey's network, which establishes and maintains the fundamental geodetic control framework for the United States. Trigonometric stations serve as primary control points for surveying operations, mapping projects, and engineering applications across their respective regions. Located near Portland, Oregon at coordinates 45.52686°, -122.66026°, this point contributes to the horizontal control network essential for accurate positioning work in the Pacific Northwest. Trig stations of this classification historically supported large-scale surveying by providing precisely determined positions that surveyors could occupy and reference. Verification and documentation of such benchmarks remain valuable for surveyors and engineers requiring reliable control for local projects. Maintaining records of these geodetic monuments ensures continuity of spatial reference systems and supports ongoing positional accuracy in surveying practice.
