TROUT — NGS PY0904 — Park County, US

This trigonometric station is part of the National Geodetic Survey's network of reference points that form the foundation of the United States' horizontal and vertical control infrastructure. Located in Park County, Wyoming, at an elevation of 2424.6 meters (ellipsoidal height), this trig point serves surveyors, engineers, and cartographers requiring precise geodetic positioning data. Such stations were historically occupied for triangulation work and continue to provide valuable reference marks for modern surveying operations and coordinate verification. The monumentation enables practitioners to establish local control networks, verify instrument calibration, and maintain consistency in spatial data collection across regions. Regular documentation and confirmation of these benchmarks ensures the reliability of positioning information critical to infrastructure development, boundary determination, and geospatial analysis throughout the surveying profession.
