This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Trigonometric stations of this class serve as primary reference points for horizontal control, enabling surveyors and mapping professionals to reference their work to a consistent national datum. Located near Portland, Oregon, at coordinates 45.52667° N, 122.65833° W, this benchmark contributes to regional geodetic infrastructure supporting civil engineering, land surveying, and geographic information systems applications. Trig stations typically were established at elevated or prominent locations to facilitate sight lines between network points. Documentation and periodic verification of such control points remain essential for maintaining positional accuracy across surveying projects. The NGS network continues to serve as the authoritative source for horizontal control data, supporting both legacy surveys and contemporary mapping efforts relying on these established references.
