This triangulation station is part of the National Geodetic Survey's network of reference points that establish the geometric framework for mapping and surveying across the United States. Located near Rollinsford, New Hampshire, at latitude 43.21583° north and longitude 70.83500° west, this trig point serves as a fixed control station for horizontal positioning and coordinate reference. Trig stations of this type were historically observed and computed to support large-scale geodetic networks, enabling surveyors and engineers to maintain positional accuracy across extended areas. Modern practitioners continue to value the documentation and verification of such established control points, as they provide continuity with historical survey work and support quality assurance in contemporary surveys. Confirming the physical monument condition and coordinate accuracy of NGS benchmarks remains important for professional surveying practice and spatial data integrity.
