This triangulation station is part of the National Geodetic Survey network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Located near Portland, Oregon at coordinates 45.54083° N, 122.69889° W, this trig point serves as a reference station for precise horizontal positioning in the region. Triangulation stations of this type historically formed the backbone of geodetic control before modern satellite positioning systems. They remain valuable for validating contemporary measurements, establishing local survey networks, and documenting the historical geodetic infrastructure. The point's position on the NGS registry enables surveyors and engineers to tie local work to the national datum system. Verification and maintenance of such benchmark records ensures continuity in surveying standards and supports both public works and private surveying activities. Documenting the physical condition and accessibility of control points preserves critical reference information for the surveying community.
