U 355 — NGS KK0427 — Denver, US

This geodetic reference point is a triangulation station within the NGS network, which establishes the foundational control framework for surveying and mapping activities throughout the United States. Located near Denver, Colorado, at coordinates 39.70167° N, 104.99056° W, this trig point serves as a fixed spatial reference for precise positioning work. Triangulation stations of this type historically provided horizontal control through intervisible networks of monumented points. The location in the Front Range region contributes to regional geodetic infrastructure supporting cadastral surveys, engineering projects, and coordinate system maintenance. Verification and documentation of such benchmarks remain valuable for confirming historical measurements, validating modern positioning techniques against legacy networks, and understanding the evolution of surveying standards. Maintaining accurate records of control points ensures continuity of spatial reference systems essential to professional surveying practice.
