This triangulation station is part of the National Geodetic Survey's network of fundamental control points that establish the geometric framework for surveying and mapping across the United States. Located near Rocky River, Ohio, at coordinates 41.48361° N, 81.83839° W, this trig point serves as a reference for determining positions of subordinate survey monuments and geographic features. Triangulation stations of this type were historically occupied using theodolites to measure angles between distant points, enabling surveyors to establish horizontal control across large areas. The point contributes to the national geodetic datum and supports subsequent surveying work including property boundary determination, engineering projects, and cartographic accuracy. Verification and documentation of such benchmarks remains important for quality assurance in modern surveying practices. Surveyors should confirm the monument's current condition and accessibility before use in any control network extension or densification project.
