This triangulation station is part of the National Geodetic Survey's network, which forms the foundational control infrastructure for surveying and mapping across the United States. Located near Denver, Colorado, at coordinates 39.74297° N, 105.00110° W, this trig point serves as a positional reference for ground surveys, engineering projects, and cartographic work in the region. Triangulation stations of this type have historically provided precise horizontal control by establishing intervisible points across the landscape. The documented ellipsoidal elevation of 1570.5 meters contributes to three-dimensional surveying applications. Verification and maintenance of such reference points remain essential to surveying practice, ensuring that local and regional surveys maintain geometric consistency with the national datum and can be reliably tied to the broader geodetic framework upon which modern spatial data infrastructure depends.
