This triangulation station is part of the National Geodetic Survey's network of reference points, which forms the foundation of the United States' official geodetic control system. Located near Portland, Oregon at approximately 45.53833° N, 122.71389° W, this trig point serves as a fixed spatial reference for surveying and mapping activities across the region. Triangulation stations of this type were historically established to create a framework of precisely positioned monuments enabling accurate geodetic measurements and coordinate determination. The benchmark contributes to the broader NGS network supporting civil engineering, land surveying, and geographic information system applications. Verification and maintenance of such reference points remain important for ensuring the integrity and reliability of surveying work, property boundary establishment, and infrastructure development across the surveyed area.
