This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping across the United States. Located near Oakland, California, at coordinates 37.85167° N, 122.23972° W, this trig point serves as a monumented reference for horizontal positioning. Triangulation stations of this type historically provided precise geodetic control by establishing intervisible networks across regions, enabling surveyors and engineers to reference their local work to the national datum. The point's location in the San Francisco Bay Area reflects the NGS's systematic coverage of populated and developed regions. Documentation and verification of such control points remain important for maintaining geodetic infrastructure integrity and supporting contemporary positioning work, particularly where legacy survey networks continue to inform modern geospatial activities.
