DR M — NGS DH9133 — Denver, US

This triangulation station is part of the National Geodetic Survey network, which establishes the fundamental horizontal control framework for the United States. Trig stations serve as precisely positioned reference points used to support surveying operations, mapping projects, and engineering applications across multiple jurisdictions. Located in the Denver, Colorado metropolitan area, this benchmark provides geodetic control for regional survey work in a densely populated zone requiring accurate positional reference. The coordinates 39.85369° N, 104.68091° W define its horizontal position within the national coordinate system. Verification and maintenance of such control points remain essential for surveyors and engineers performing boundary surveys, construction staking, and geographic information system development. Regular documentation of benchmark condition and accessibility ensures continued utility of the geodetic network for professional surveying practices and public infrastructure projects.
