This triangulation station is part of the National Geodetic Survey's fundamental control network, which establishes the geometric foundation for surveying and mapping across the United States. Located near Portland, Oregon at coordinates 45.54333°N, 122.51306°W, this trig point serves as a fixed reference for regional survey work and spatial data collection. Triangulation stations of this class provide precise horizontal control through intervisible networks of monumented points. Surveyors and mapping professionals rely on such benchmarks to orient their local surveys to the national datum and ensure consistency across large-scale projects. Documentation and periodic verification of these control points remain essential to maintaining the integrity of the geodetic infrastructure. Even points with incomplete elevation records contribute valuable horizontal positioning data to the surveying community. Maintaining accurate records of such monuments supports both modern surveying operations and the long-term stability of the national coordinate reference system.
