The Zero Milestone is a zero mile marker monument in Washington, D.C. intended as the initial milestone from which all road distances in the United States should be reckoned when it was built. At present, only roads in the Washington, D.C. area have distances measured from it. ==Location== The monument stands just south of the White House at the north edge of the Ellipse, within President's Park. Atop the monument is a bronze 16-point compass rose with a very small worn-down pyramid at its center whose top serves as a National Geodetic Survey benchmark (HV1847).〔(【引用サイトリンク】title=Washington Monument GPS Height Modernization Project )〕 * Coordinates: (NAD83)〔(Zero Milestone HV1847 NGS Data Sheet )〕 * Altitude: 8.384 m (27.507 ft) (NAVD88)〔(【引用サイトリンク】title=GPS on Benchmarks )〕
