This triangulation station is part of the NGS network, which establishes and maintains the foundational control points for the Nation's surveying and mapping infrastructure. As a trig station, this point was established to provide accurate horizontal positioning through triangulation methods, serving as a reference for subsequent surveys and engineering projects across the region. Located in Jackson County, South Dakota, the station occupies a position within the Northern Great Plains geodetic framework. Triangulation stations of this type typically occupy elevated or otherwise strategically visible locations to facilitate intervisibility with other control points. The coordinates 43.85056°N, 101.92000°W define this reference point's position within the National Spatial Reference System. Verification and documentation of such benchmarks remains essential for surveyors, cartographers, and civil engineers who depend on accurate horizontal control. Periodic inspection of established stations helps maintain the integrity of regional survey networks and supports both public works and private surveying operations.
