This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental geodetic control framework for the United States. Located near Gresham, Oregon, at coordinates 45.54102°N, 122.47622°W, this trig point serves as a reference monument for surveying and mapping operations across the region.
Triangulation stations of this type were historically established to create precise horizontal control networks through intervisible point measurements. Modern surveyors rely on documented benchmarks to verify positioning accuracy, support cadastral surveys, and maintain consistency in large-scale mapping projects.
Verification and documentation of such geodetic monuments remain valuable for professional surveying practice, ensuring continuity of spatial reference systems and supporting infrastructure development, land management, and scientific applications dependent on accurate coordinate data.
