This issue resurfaced briefly in 2009 with U.S. media reports that the monument was placed west of its intended location. This was soon found to be the result of a mistaken assumption: that the Prime Meridian, used in the United States since 1912, was used. In actuality, the 19th century surveys used the previous Washington meridian. A spokesperson for the U.S. National Geodetic Survey (USNGS) has stated that the USNGS has determined that the modern monument is located roughly east of where the Four Corners marker had originally been intended to be located by the US Congress in 1863. The spokesperson, however, reiterated that the 1875 survey was accepted by all states and therefore its markers, including the Four Corners Monument, are legally binding. Similar statements were issued by the Navajo Nation, defending their work in maintaining and promoting the monument.
