This triangulation station is part of the NGS network, which provides the foundational geodetic control for surveying and mapping throughout the United States. Located near Portland, Oregon at coordinates 45.49863°, -122.59175°, this trig point serves as a fixed reference for establishing horizontal positions across regional survey projects. Triangulation stations of this type historically formed the backbone of precise geodetic networks, enabling surveyors to measure distances and angles between known points. Such marks remain valuable for verification and densification of control networks, particularly in areas where modern positioning techniques benefit from integration with established datums. Documentation and maintenance of these reference points support land surveying, infrastructure development, and scientific research requiring reliable spatial references. Verification of existing marks contributes to the integrity of the broader geodetic framework.
