In 1925, some 57 years after Congress had first attempted to specify the spot, the problems surrounding the originally misplaced marker were brought up before the US Supreme Court. In order to amicably remedy this original surveying error, the US Supreme Court then redefined the point of the Four Corners, officially moving the Four Corners point roughly 1,800 feet (550 m) east, to where the original survey had first held it to be all along, and where it remains to this day, duly marked.[6] This initial survey error has resulted in some longstanding misunderstandings about the correct location of the Four Corners marker, some of which remain to this day.

well shoot. I guess I gobbled up this longstanding misunderstanding, even though it has been corrected for longer than it was ever wrong.
