This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental geodetic reference framework for the United States. As a trigonometric point, it served to control horizontal positions through intervisible sight lines, supporting both large-scale mapping projects and local surveying activities. Located in Baltimore County, Maryland, at coordinates 39.39209°N, 76.78776°W, this benchmark occupies a strategic position within the regional survey network. Triangulation stations like this provided essential spatial control before modern satellite positioning methods became standard. Verification and documentation of such monuments remains valuable for historical survey recovery, coordinate transformation validation, and understanding the evolution of geodetic practices. Professional surveyors often reference these established points when conducting boundary surveys or large-scale projects requiring high-accuracy horizontal control. Maintaining records of these stations supports continuity in surveying practice and geodetic science.
