This triangulation station is part of the National Geodetic Survey's network of reference points that establish the geometric framework for surveying and mapping across the United States. Trig stations serve as fixed control points used to determine precise horizontal positions and elevations for subsequent surveys and construction projects. Located in Pennington County, South Dakota, this benchmark contributes to the broader NGS control network that supports cadastral surveys, engineering projects, and cartographic work throughout the region. The documented coordinates provide surveyors with a reliable reference for local surveys and spatial measurements. Verification and maintenance of such geodetic control points remain important for ensuring consistency in surveying practices and mapping standards. Professionals conducting fieldwork in this area may reference this station when establishing survey networks or validating equipment accuracy. Current positional information and accessibility conditions should be confirmed through the NGS database before field use.
