This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Located in Haakon County, South Dakota, at coordinates 44.11052° N, 101.67264° W, this trig point serves as a precisely documented reference for geodetic and surveying operations across the region. Triangulation stations of this type provide fixed, monumented control points essential for establishing accurate horizontal and vertical positioning. The ellipsoidal elevation of 690.8 meters references the geometric shape of the Earth rather than local vertical datum. Professional surveyors, engineers, and geospatial professionals depend on verification and documentation of such benchmarks to maintain the integrity of cadastral surveys, infrastructure projects, and mapping initiatives. Periodic field validation ensures these points remain reliable references for current and future surveying work in this area of South Dakota.
