7717 CANYON — NGS DO5621 — Coconino County, US

This triangulation station is part of the National Geodetic Survey's classical trig network, which forms the foundation of the Nation's horizontal geodetic control. Located in Coconino County, Arizona, at coordinates 36.32158° N, 112.25300° W, this point serves as a reference for establishing precise horizontal positions across the region. Triangulation stations of this type were established to provide survey-grade control points for mapping, engineering projects, and scientific applications. The benchmark's documented location enables surveyors and geodesists to verify their own measurements and maintain consistency in local and regional surveys. Proper documentation and periodic verification of such control points remain essential for maintaining the accuracy and reliability of the geodetic network. Their preservation ensures continuity of surveys and supports infrastructure development, land administration, and cadastral work across Arizona.
