Summary
DescriptionBoundary of New Mexico, Colorado, Arizona, and Utah (92907195).jpg |
Media reports sometimes claim that the monument was not placed in the intended location. The American Surveyor Magazine has responded to these stories claiming the boundary surveys for the New Mexico – Arizona border were accurate. They explain that the reference point used by the U.S. Congress at the time was the Washington Meridian, which has an offset from the modern reference, the Prime Meridian. This offset is often missed by those not familiar with the history of American surveying. The geography department at the University of Oregon teaches that this offset can be ignored to simplify estimates of distance, but the simplification results in an error of between 2.3 miles (3.7 km) and 3 miles (4.8 km). A common claim is the monument was misplaced 2.5 miles (4.0 km) west of the true Four Corners, within this range.
