 Even after the mistakes in the reports were discovered , a spokesperson for the U.S. National Geodetic Survey admitted the monument is placed 1 @,@ 807 feet ( 551 m ) east of where modern surveyors would mark the point . However , he defended the accuracy of the original survey , stating surveyors " nailed it " considering the primitive tools of the day . Pointing out the achievement given the conditions , he further stated , " Their ability to replicate that exact point — what they did was phenomenal , what they did was spot on . " He concluded by stating that any claims of errors in the location of the monument are irrelevant . Once a survey commissioned to establish a boundary has been accepted by the involved parties , the survey markers are legally binding , regardless of any error that is later discovered . Similar statements were issued by the Navajo Nation , defending their work in maintaining and promoting the monument . In addition , general U.S. land principles , law , and the Supreme Court have established that the location of the monument is the legal corner of the four states .
