This triangulation station is part of the National Geodetic Survey's network of control points that form the foundational framework for precise surveying and mapping throughout the United States. Located near Vancouver, Washington at coordinates 45.63129°N, 122.61171°W, this trig point serves as a reference station for establishing horizontal position control in the Pacific Northwest region.
Triangulation stations of this type have historically provided surveyors and mapmakers with monumented positions of known accuracy, enabling local surveys to be tied into the national geodetic datum. The documented coordinates allow surveyors to verify and reference their own measurements against established control. Verification and proper documentation of such control points remain valuable for maintaining the integrity of cadastral records, infrastructure projects, and regional mapping efforts.
