This NGS triangulation station is a primary control point within the National Geodetic Survey's network, which forms the foundation of the United States' horizontal geodetic reference framework. Located near Alameda, California, at coordinates 37.77718°, -122.27042°, this trig point was established to provide accurate positional control for regional surveying, mapping, and engineering projects across the San Francisco Bay Area. Triangulation stations of this class typically served as fixed reference monuments for conventional survey networks before the advent of GPS technology. The point's recovery and verification remain valuable for practitioners conducting heritage surveys, validating modern satellite-derived positions against established datums, and maintaining continuity in local survey control systems. Documentation and maintenance of such benchmarks ensure the integrity of historical survey records and support quality assurance in contemporary geodetic work.
