This triangulation station is part of the National Geodetic Survey network, which establishes and maintains the fundamental geodetic framework for the United States. Trig stations such as this serve as primary control points for surveying, mapping, and engineering projects across their regions. Located near Portland, Oregon, at coordinates 45.57556° N, 122.60194° W, this benchmark provides vertical and horizontal reference data essential for local and regional survey work. The NGS network supports cadastral surveys, infrastructure development, and scientific applications requiring precise positional control. Documentation and verification of active geodetic monuments remain critical to maintaining the integrity of the national spatial reference system. Surveyors and geospatial professionals depend on accurate benchmarks to ensure consistency across projects and to detect ground movement or subsidence in tectonically or hydrogeologically active regions.
