This triangulation station is part of the National Geodetic Survey's network of control points that form the foundational framework for geodetic surveying and mapping across the United States. Positioned in Travis County, Texas, at coordinates 30.33486° N, 97.51142° W, this trig point serves as a reference for establishing horizontal positions and elevations in regional survey work. Triangulation stations of this classification were historically established to create a network of precisely located points accessible to surveyors conducting cadastral, engineering, and cartographic projects. Modern surveyors rely on verification and documentation of existing benchmarks to maintain consistency in local coordinate systems and to validate contemporary positioning methods including GNSS observations. The continued identification and maintenance of such control points remains valuable for quality assurance in surveying practice and for preserving institutional knowledge of the nation's geodetic infrastructure.
