C 407 — NGS KK1511 — Aurora, US

This triangulation station is part of the National Geodetic Survey's horizontal control network, which establishes the geometric framework for surveying and mapping throughout the United States. Located near Aurora, Colorado, at coordinates 39.70082° N, 104.81015° W, this trig point serves as a reference for determining positions of other survey monuments and geographic features across the region. Triangulation stations of this type were historically observed and computed to provide accurate horizontal datums for professional surveying work. The point's documented location enables surveyors and engineers to reference precise positions for property boundaries, infrastructure projects, and cartographic applications. Verification and maintenance of such benchmarks remain important for quality assurance in surveying practice and for preserving the continuity of geodetic control networks that support civil and cadastral surveys throughout Colorado and adjacent areas.
