This triangulation station is part of the National Geodetic Survey's network, which establishes the geometric foundation for surveying and mapping across the United States. Positioned near Alameda, California, at latitude 37.77528° and longitude -122.30194°, this trig point served as a reference for horizontal control in the San Francisco Bay Area region. Triangulation stations of this type were historically observed and occupied to create networks of known positions, enabling surveyors to reference local measurements to a consistent geodetic datum. Modern verification and documentation of such points remains valuable for establishing continuity between classical survey networks and contemporary positioning systems. Surveyors and geodetic professionals benefit from confirming the continued existence and accessibility of these reference marks, which may serve specialized applications or historical research purposes.
