century surveys used the previous Washington meridian. A spokesperson for the U.S. National Geodetic Survey (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. COVID-19 closures From 2020 to 2021, the Four Corners Monument was closed to the public as part of Navajo Nation coronavirus safety regulations. The monument was reopened in 2021, with a requirement for visitors to wear masks.
