This triangulation station is part of the National Geodetic Survey's control network, which establishes the foundational geometric framework for surveying and mapping activities across the United States. Trig stations serve as precise horizontal control points, typically established through classical triangulation methods to support cadastral surveys, engineering projects, and geographic information systems. Located in Jackson County, South Dakota at coordinates 43.82409° N, 101.93622° W, this benchmark contributes to regional positional accuracy and spatial reference infrastructure. The point's monumentation and survey records provide surveyors and GIS professionals with reliable datum ties for local work. Verification and documentation of such control points remain valuable for maintaining the integrity of the national survey network, particularly in areas where original monuments may be obscured or displaced. Proper stewardship of these geodetic references supports accurate land administration and infrastructure development.
