U 407 — NGS KK1505 — Aurora, US

This triangulation station is part of the National Geodetic Survey's network of control points that establish the geometric framework for mapping and surveying across the United States. Located near Aurora, Colorado, at coordinates 39.65333° N, 104.82194° W, this trig point serves as a fixed reference for local and regional survey work. Triangulation stations of this type were established to provide surveyors with monumented positions of known coordinates. These points enable accurate determination of distances, directions, and elevations in subsequent surveys and engineering projects. The NGS network remains fundamental to cadastral surveying, infrastructure development, and scientific applications requiring precise spatial reference. Documentation and verification of such benchmarks is essential for maintaining geodetic integrity. Surveyors conducting work in the Aurora area may reference this point to establish local control networks. Current condition assessment and coordinate confirmation ensure this station continues contributing to accurate surveying practice.
