On a ranch 18 miles southeast of this marker a bronze plate marks the most important spot on this continent to surveyors and map makers. Engraved in the bronze is a cross-mark and on the tiny point where the lines cross depend the surveys of a sixth of the world's surface. This is the Geodetic Center of the United States, the "Primary Station" for all North American surveys. It was located in 1901 by the U.S. Coast and Geodetic Survey. Later Canada and Mexico adopted the point and its supporting system as the base for their surveys and it is now known as the "North American Datum." What Greenwich is to the longitude of the world, therefore, a Kansas pasture is to the lines and boundaries of this continent. It must not be confused with the Geographic Center of the United States, which is 42 miles north, in Smith County.
