This triangulation station represents part of the National Geodetic Survey's foundational control network, established to support precise surveying and mapping across the United States. Located near Chicago, Illinois, at coordinates 41.72217° North, 87.59180° West, this trig point serves as a reference monument for horizontal geodetic control. Triangulation stations of this type were historically observed and incorporated into the NGS network to establish accurate positional relationships across regions. Such monuments remain valuable for verifying existing survey work, conducting cadastral surveys, and maintaining spatial data consistency. The point's documented coordinates enable surveyors and engineers to tie local projects to the national datum. Modern surveyors benefit from locating and confirming the physical condition of these reference points, as they continue to anchor regional surveying activities. Proper documentation and preservation of benchmark locations support the integrity of cadastral records and engineering infrastructure throughout the Chicago metropolitan area.
