Q 207 — NGS FF1421 — White County, US

This triangulation station is part of the National Geodetic Survey's horizontal control network, which establishes the foundational reference framework for surveying and mapping across the United States. Located in White County, Arkansas, at coordinates 35.10678° N, 91.89075° W, this trig point serves as a monumented control station for precise geodetic positioning. The ellipsoidal elevation of 46.0 meters provides vertical reference data for the region. Triangulation stations of this type historically formed the backbone of large-scale survey networks, enabling surveyors and engineers to reference their work to a common coordinate system. Verification and documentation of existing benchmarks remain valuable for quality assurance in modern surveying projects, GPS network densification, and maintaining the integrity of the national spatial reference system.
