This triangulation station is part of the NGS network, which comprises the primary geodetic control framework for the United States. Trig points serve as reference stations for horizontal position control in surveying and mapping operations. Located in Contra Costa County, California, at coordinates 37.81785° N, 122.17658° W, this benchmark contributes to the established network of monumented survey control points across the country. Such stations historically supported both large-scale topographic mapping and subsequent cadastral surveys. Modern practitioners continue to value these points for verification of survey networks, GPS validation, and establishing local control for engineering projects. Proper documentation and maintenance of these reference marks preserves the integrity of California's geodetic infrastructure and ensures consistency in coordinate systems used for land records, infrastructure development, and geographic analysis.
