This triangulation station is part of the National Geodetic Survey's network of control points that form the foundation of the United States' geodetic infrastructure. Located in the Saint Thomas-Saint John District of the United States Virgin Islands, this trig point serves as a horizontal reference marker for surveying and mapping operations throughout the territory. Triangulation stations of this type were established to provide accurate positional control for cadastral surveys, engineering projects, and geographic information systems. The coordinates 18.34303°, -64.96875° define its location within the NAD framework. Verification and documentation of such benchmarks remains valuable for surveyors conducting precision work, as these points anchor local surveys to the national geodetic datum. Regular confirmation of monument condition and coordinate accuracy supports the integrity of surveying records and property boundary determinations in the region.
