This triangulation station is part of the National Geodetic Survey's legacy network, which forms a foundational component of the United States' horizontal geodetic control infrastructure. Situated near Orinda, California at coordinates 37.88056° N, 122.21472° W, this trig point served to establish precise positional references across the region through classical surveying methods. Triangulation stations of this type were integral to large-scale mapping and survey projects, providing monumented ground control points from which surveyors could reference subsequent measurements. The NGS network continues to support numerous applications including land surveying, engineering projects, and geographic information systems. Verification and documentation of such benchmarks remain valuable for surveyors and geodesists, particularly when evaluating the integrity of older control networks and understanding historical survey methodologies. Current elevation data may be supplemented through modern techniques when required for specific applications.
