This triangulation (trig) station is part of the National Geodetic Survey's fundamental control network, which establishes the geometric framework for surveying and mapping across the United States. Located in Maricopa County, Arizona at coordinates 33.49472° N, 111.82306° W, this benchmark serves as a reference point for horizontal positioning in its region. Trig stations of this classification typically function as vertices in triangulation networks, providing accurate horizontal control for subsequent surveys and engineering projects. The NGS maintains such points as part of the national geodetic infrastructure, supporting cadastral surveys, infrastructure development, and scientific applications. Verification and documentation of existing benchmarks remain essential for maintaining network integrity and ensuring the accuracy of dependent surveys. The coordinates of this station provide surveyors and engineers with reliable reference data for local positioning work. Current elevation data for this point should be obtained from NGS records or field verification as needed.
