This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental geodetic control framework for the United States. Triangulation stations of this type served as primary horizontal control points, historically observed through reciprocal sightings to distant stations to create networks of known positions. Located near Maplewood, Missouri, at coordinates 38.60437° N, 90.32461° W, this benchmark contributes to regional survey coverage in the St. Louis area. Such points remain valuable reference monuments for professional surveyors conducting boundary determinations, engineering projects, and local control network establishment. Contemporary verification and documentation of these legacy points preserves the institutional knowledge embedded in the geodetic infrastructure. Surveyors benefit from accessing stable, monumented reference positions, particularly in developed areas where new survey control establishment presents logistical challenges. This station's continued maintenance supports both historical geodetic continuity and practical surveying operations.
