RV 253 — NGS FR0035 — Coconino County, US

This triangulation station is part of the National Geodetic Survey's extensive control network that establishes the fundamental geodetic framework for the United States. Trig stations serve as primary control points for surveying and mapping operations, providing precise horizontal positioning references across regions. Located in Coconino County, Arizona, at coordinates 35.88222° north latitude and 112.23972° west longitude, this point contributes to the overall accuracy and reliability of surveying work throughout northern Arizona. Triangulation stations were historically established through intervisibility networks and precise angular measurements, creating a hierarchy of control points for subsequent surveys. Documentation and verification of such benchmarks remain important for surveying professionals conducting boundary surveys, engineering projects, and geospatial work. Maintaining accurate records of these reference points ensures consistency in surveying practice and supports the integrity of cadastral and infrastructure development activities in the region.
