F 12 — NGS PY0004 — Park County, US

This triangulation station is part of the National Geodetic Survey network, which establishes the fundamental geodetic control framework for the United States. Triangulation (trig) stations serve as precisely positioned monuments that support surveying, mapping, and infrastructure development across the nation. Located in Park County, Wyoming, at coordinates 44.51556° N, 110.25389° W, this benchmark contributes to regional horizontal control. Trig stations of this type were historically established through intervisible networks and remain valuable reference points for modern surveying operations, GPS validation, and local project control. Verification and documentation of such monuments ensure their continued utility for professional surveyors and engineers. Maintaining accurate records of these established control points supports the integrity of the nation's surveying infrastructure and facilitates connection between contemporary measurements and historical geodetic work.
