This triangulation station is part of the National Geodetic Survey's foundational control network, which establishes the geometric framework for surveying and mapping activities across the United States. Located near Baltimore, Maryland at coordinates 39.25669°N, 76.53185°W, this trig point serves as a reference monument for horizontal positioning. Triangulation stations of this type were historically observed and computed to create networks of known positions with high relative accuracy. Such points remain valuable for validating survey work, establishing local control networks, and documenting the historical geodetic infrastructure. Their continued verification and documentation supports surveying professionals in quality assurance, datum transformations, and large-scale projects requiring precise spatial reference. Surveyors and geodesists should verify the current condition and accessibility of this benchmark before field use, as physical monuments may have been disturbed or destroyed since original establishment.
