This triangulation station is part of the NGS network, which maintains the primary geodetic framework for the United States. Trig points serve as fundamental control stations for surveying and mapping activities across the country. Located near Portland, Oregon at coordinates 45.61291°N, 122.67857°W, this benchmark provides vertical and horizontal reference data for regional surveys and construction projects. Triangulation stations like this one establish precise positional control through intervisible networks, enabling surveyors to tie local measurements to the national datum. The absence of recorded elevation data indicates potential documentation gaps that should be verified by field inspection. Locating, verifying, and updating such monuments remains valuable for maintaining survey accuracy and infrastructure planning in the Portland metropolitan area. Professional surveyors should conduct on-site reconnaissance to confirm the station's condition and establish current vertical control if needed.
