This triangulation station is part of the National Geodetic Survey's trig network, which forms a foundational component of the United States' horizontal control infrastructure. Located in King County, Washington, at coordinates 47.49801° N, 121.99888° W, this point serves as a reference station for surveying and mapping operations throughout the region. Triangulation stations of this type were established to provide accurate positional control for cadastral surveys, engineering projects, and cartographic work. The trig network historically enabled surveyors to extend precise measurements across large areas through geometric observation methods. Verification and continued documentation of such benchmark points remains valuable for professionals conducting land surveys, infrastructure development, and geodetic research. Even where elevation data may be incomplete, the horizontal coordinates provide an established reference that supports modern positioning standards and validates historical survey work.
