This geodetic trig station is part of the National Geodetic Survey's network, which establishes the fundamental horizontal and vertical control framework for surveying and mapping across the United States. Located in Park County, Wyoming, this triangulation point serves as a reference for precise positioning in the region. Trig stations of this classification are typically monumented ground points used to support cadastral surveys, engineering projects, and geographic information systems. The coordinate values provided establish its location within the national spatial reference system. Verification and documentation of such control points remain essential to surveying practice, as they enable surveyors to verify instrument calibration, validate survey closures, and maintain consistency with established geodetic datums. Maintaining accurate records of these monuments supports continued infrastructure development and land administration throughout the state.
