This triangulation (trig) station is part of the National Geodetic Survey's network of control points that forms the foundation of North America's surveying and mapping infrastructure. Located near St. Louis, Missouri, at coordinates 38.62750°N, 90.24528°W, this point serves as a reference for establishing accurate horizontal positions in the region. Trig stations of this classification are typically situated at elevated or strategically visible locations to facilitate sightline measurements between control points. Such markers enable surveyors and mapping professionals to maintain positional accuracy across survey projects, property demarcation efforts, and spatial data collection activities. The NGS registry preserves documentation of these benchmarks to support the continuity and reliability of the national control network. Verification and accurate recording of such reference points remain essential for professional surveying practice and ensure consistency in geographical positioning across generations of surveying work.
