This triangulation station is part of the National Geodetic Survey network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Trigonometric stations serve as precisely positioned reference points for horizontal control, enabling surveyors and cartographers to tie their local work to the national coordinate system. Located near Issaquah, Washington, this benchmark contributes to geodetic coverage in the Pacific Northwest region. The station's coordinates are referenced to the national datum, providing surveyors with reliable control points for property surveys, engineering projects, and geographic information system applications. Verification and documentation of such control points remains important for maintaining the integrity of the national surveying infrastructure. Surveyors regularly recover and reoccupy these marks to confirm their stability and utility for contemporary surveying operations. The accessibility and condition of established benchmarks directly support the accuracy and efficiency of surveying work across the region.
