This triangulation station is part of the National Geodetic Survey's network of reference points that establish the geometric framework for surveying and mapping across the United States. Trig stations of this type serve as control points for horizontal positioning, enabling surveyors and cartographers to reference local measurements to the national coordinate system. Located near Chicago, Illinois, this point contributes to the geodetic infrastructure supporting civil engineering, land surveying, and geographic information systems throughout the region. The station's coordinates at 41.72250°N, -87.54750°W are recorded in the NGS database. Verification and documentation of such benchmarks remain valuable for confirming positional accuracy in modern surveys, particularly when employing legacy control networks or conducting heritage surveys. Current condition and accessibility information should be verified directly with NGS for field operations.
