This triangulation station is part of the National Geodetic Survey's network, which forms the foundation of horizontal control for surveying and mapping throughout the United States. Located near Baltimore, Maryland, at coordinates 39.26696° N, 76.58057° W, this trig point serves as a fixed reference for establishing positions of other survey monuments and geographical features. Triangulation stations of this type were historically established to create precise geodetic networks through intersecting sight lines between elevated points. Such monuments enable surveyors and engineers to conduct accurate boundary surveys, infrastructure projects, and cartographic work within the region. Documentation and periodic verification of these control points remains valuable for the surveying community. Confirmation of station integrity and coordinate accuracy helps ensure the reliability of contemporary surveys that depend upon these historical geodetic references as part of the integrated national control network.
